2.1 PROJECT BACKGROUND AND GOALS

The National Museum of Natural History, located on the National Mall in Washington, DC, is one of the most visited museums in the world, welcoming millions of visitors annually. At 1.3 million square feet, the museum houses exhibitions, collections spaces, visitor amenities, and educational, scientific and administrative facilities, with a permanent staff of approximately 1,200 people and thousands of visitors daily.

The building’s existing fire alarm panels (Siemens MXL) have become obsolete and will soon not be compatible with newer Siemens systems (XLS). Due to safety, maintenance and reliability concerns, as well as non-compliant clearances at fire alarm panels, the Smithsonian Institution has deemed it necessary to upgrade the fire alarm system to the current Siemens XLS system and make the necessary corrections to non-compliant conditions. Due to the complexity of the system, importance of the museum, and established relationship between Siemens and SI, Siemens will be the sole manufacturer for the new fire alarm system.

Additionally, the museum does not currently have a holistic, integrated method for mass notification in the event of emergencies. Given the fire alarm system upgrade, this project is an opportunity for the museum to integrate a mass notification system (MNS) with the upgraded fire alarm system.

The design team prepared a Feasibility Study for upgrading the building’s fire alarm panels and mass notification system. The feasibility study phase began with a series of surveys to document the existing fire alarm system and the various means of mass notification currently utilized in the building. The acoustical characteristics of select spaces throughout the building were studied to subsequently generate acoustical models for intelligibility of the mass notification system. An existing conditions document with preliminary recommendations was prepared and issued to SI.

A draft report was then prepared, representing the design team’s initial recommendations for the fire alarm and mass notification system upgrades, based on the team’s expertise, existing conditions within the building and the institutional knowledge gleaned from the various project stakeholders. SI identified the upgrade of the fire alarm panels as the highest priority of this project scope, given the imminent obsolescence of the Siemens MXL panels. It is anticipated that the fire alarm and mass notification work will take place as a building-wide upgrade over a series of phases corresponding with the major portions of the building (East Wing, East Court, etc.)

The final report and cost estimate incorporated all SI stakeholder comments from the various reviews and follow-up discussions/coordination sessions throughout the study. The culmination of an iterative process and collaborative effort between the design team and SI stakeholders, the feasibility study formed the basis of this project scope and established the requirements for this building-wide upgrade to the fire alarm panels and mass notification system. The design team greatly appreciates the SI stakeholders’ valuable insight into the details and operational aspects of both systems and looks forward to embarking on the design and implementation phases to come.

Please refer to Section 1.1 for a detailed listing of the project scope.

2.3 SUMMARY OF DESIGN ISSUES

The following sections are a summary of design issues and topics that will require investigation during the design phase of this project.

2.3.1 Impact on Historic Fabric

Special consideration must be given to historic spaces within the building. The hard surfaces and spatial volumes of the Rotunda and Grand Halls pose significant acoustical challenges to meeting mass notification system intelligibility requirements. Additional speakers get closer to intelligibility targets but detract from the historic character of the spaces and is not an acceptable solution.

The design team will study ways to integrate speakers into existing fixtures, exhibitory and building signage/wayfinding to achieve an acceptable level of intelligibility while maintaining the integrity of the historic building fabric and character of the space. Additionally, the design team will study distribution pathways for wiring to speakers and other devices that are discretely located and out of public view.

35% Submission Update:

As part of Workshops 1 and a subsequent Historic Preservation-focused follow-up meeting, the design team reviewed various approaches to locating speakers and mass notification devices within the Natural History Building’s historic spaces. With input from the project stakeholders, the

EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 PAGE 2-3 following guidelines governing placement of speakers and mass notification system devices and components in historic/public spaces were established:

Locate line array speakers to the sides of architectural elements where possible (versus centered on pilasters or other architectural elements)

Consider overall composition where devices are located in relation to other devices and architectural features

Attachments through plaster are preferred over attachments through stone because plaster can be patched/repaired; penetrating stone should be avoided to the greatest extent possible

Attachment methods should be mechanical (in lieu of adhesive) and reversible

Mechanical attachments should clamp to beams in lieu of welding to avoid disturbing associated hazardous materials

Faux finishes for line array speaker covers should be considered

The design team will further investigate wire mold ratings and details (refer to update in the Architecture section of this report)

Devices may be placed at mid-level cornice and any places where lights are located and accessible

Details of wire pathways in historic/public spaces are required to capture the scope and costs associated with this detail work

Wire pathway components and distribution are described within this 35% DD Submission to capture scope and cost at this phase. Actual distribution layouts and pathways will be further developed for the forthcoming 65% CD Submission, when device locations are better defined.

2.3.2 Intelligibility Requirements

In addition to the historic spaces noted above, numerous other spaces impacted by this project may not be able to meet intelligibility requirements due to spatial volume, equipment noise, etc.

Through the design process, the design team will make the project stakeholders aware of these conditions, determine the intelligibility level of each location in question, and work with OSHEM and the project stakeholders determine an acceptable level of intelligibility and intervention on the building fabric to achieve that level.

35% Submission Update:

Acoustical modeling is ongoing and will continue through the design process to confirm anticipated levels of intelligibility within the building’s various spaces. During this 35% Phase, the design team focused primarily on the Rotunda, the most acoustically (and historically) challenging space in the building given the overall volume of the space and its hard, acoustically reflective surfaces, resulting in very high reverberation times and low intelligibility.

The intent of the project is to provide the best possible intelligibility, understanding the acoustical challenges the building faces, and contingent on OSHEM approval. OSHEM shared intelligibility guidelines recently used in the National Air & Space Museum’s building renovation as a starting point for evaluating intelligibility levels in this project. These guidelines identify intelligibility requirements along with various secondary means of compliance should spaces fail to meet those requirements, including maximum distances building occupants may travel to arrive in an area of

PAGE 2-4 SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM adequate intelligibility. Any deviation from NFPA 72-defined intelligibility requirements are subject to OSHEM approval and will be reviewed in the forthcoming design phase as acoustical modeling of all spaces is completed and refined.

Preliminary acoustical modeling of the Rotunda revealed better-than-expected intelligibility levels with speakers at each level of the Rotunda’s north side. Given these initial findings, the design team is optimistic that suitable intelligibility levels and acceptable contingency plans can be achieved moving forward in design. (Please refer to the Architectural and Acoustical sections of this report for additional discussion.)

2.3.3 Impact on Exhibits

While some of the exhibit spaces in the historic Grand Halls of the Natural History Building may be acoustically challenging for the same reasons described above, the real challenge with exhibit spaces will be discretely integrating speakers and tying into video displays.

Mass notification system speakers should merge seamlessly into exhibit fixtures, taking on the individual motifs and details of the particular displays. The goal is to provide mass notification capabilities and intelligibility without calling attention to the speakers and devices. The design team will investigate ways the MNS can utilize exhibit video displays for notification purposes and return to exhibit content upon restart.

All video displays associated with the MNS are required to be on emergency power. Currently, exhibit video displays are not on emergency power, nor are the displays monitored by the building.

This will be studied during the design phase, and a determination will be made whether to pursue using video components within exhibits.

35% Submission Update:

In Workshop 2, the design team reviewed various approaches to locating speakers and mass notification devices within the building’s exhibit spaces. While the three Grand Halls share the same historic character, the various exhibits and galleries within the building include a range of ceiling conditions, collection types, and overall character that must be taken into consideration when locating the FA/MNS components. With input from the project stakeholders, the following guidelines governing placement of speakers and mass notification system devices and components in exhibits were established:

Locate speakers and devices on building elements as opposed to exhibit elements due to potential changeout of exhibitory

An independent MNS speaker system is preferred over tying the MNS into the exhibit audio

Work and access to devices over exhibits should be avoided to the greatest extent possible

Devices may be placed at mid-level cornice and any places where lights are located and accessible

Locate speakers higher up in the space and avoid locations where they can be damaged

All speakers should be on whips to allow for flexibility in exhibit changeout; numerous exhibit elements are currently installed on 3 ft. whips

100% Submission Update:

Speakers in areas subject to vibration shall be installed on whips. In all other locations, speakers shall be installed in rigid conduit.

EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 PAGE 2-5

2.3.4 Means and Levels of Mass Notification

As part of the MNS design effort, the design team will investigate various means of mass notification, including text notifications, apps, visual displays (both in exhibit and in back-of-house spaces) and numerous other formats. The goal is to provide notification functions that will reach the highest number of building occupants through the most cost-effective means.

This process will include decisions made early in the design process, including:

Which MNS functions need to be provided on day one?

Which MNS functions will be provided in the near future?

Which functions are not required?

2.3.5 Spaces Impacted by Construction

It is anticipated that most, if not all, spaces in the building will be impacted by construction and the implementation of this work. Given the requirement that the existing fire alarm system is to remain fully functional while the new system components are installed and tested before migrating the fire alarm circuits from the MXL to XLS panels, new components will likely be installed adjacent to existing (panels, devices and wiring). New fire alarm panels will be installed in the same relative location as the existing panels unless noted otherwise (refer to the Fire Alarm section of this report).

While the installation of the new fire alarm components will impact most of the building, the most widespread aspect of the work consists of wiring/distribution. Ceiling systems, materials and heights as well as location within the building are criteria in determining the overall impact the construction/installation will have on the existing building. Given the unknowns at this time with regards to wire distribution, the design team will continue to develop a list of impacted spaces and the level of impact anticipated. Please refer to the Fire Alarm section of this report for additional information.

35% Submission Update:

As noted above, wire pathways are in development and will be further defined as FA and MNS panels, devices and other components are more definitively located through the design process.

Please refer to the 35% Submission Update above, listed under 2.3.1 Impact on Historic Fabric.

2.3.6 Hazardous Materials

The design team will use the hazardous materials database, transmitted from SI, to identify areas of known hazardous materials and determine the impact on construction activities/cost. This information is not yet included in this iteration of the Basis of Design report but will be included in future versions with each design submission.

35% Submission Update:

In addition to the incidental hazardous materials in various conditions throughout the building, the area of greatest hazmat concern identified during this phase is Bone Hall. The presence of hazmat in this exhibit, coupled with the fragility and age of the collections pieces, requires a minimal

PAGE 2-6 SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM approach to implementing the required FA/MNS system components. It was decided that a single line of devices should be surface-mounted down the central spine of the space to minimize any disruption of the hazardous materials in the building components.

2.3.7 Phasing and Migration

Given the nature of this building-wide project, it is anticipated that the fire alarm system upgrade will be completed over a series of phases, likely by fire alarm node and location within the building.

The design team expects that phasing will be complex, and will be impacted by areas affected, museum operations and many other considerations. As noted above, the existing fire alarm system must remain operational until the new components are installed, tested and ready for migration.

Please refer to the Fire Alarm section of this report for additional information.

35% Submission Update:

Phasing and sequencing of construction must be coordinated with that of the NMNH Electrical

Upgrades project. The Fire Alarm/Mass Notification System Upgrade project construction is anticipated to start approximately halfway through construction of the NMNH Electrical Upgrades project. NMNH expressed the desire to avoid going back into spaces that have already been completed. Given the staggered starts of the project, this is possible for a portion of the time.

The phasing diagram below represents a preliminary look at how the two projects could potentially be sequenced during the period of overlap. It takes periods of high visitation into consideration by limiting the Main Building work to periods of regular/lower visitation and staggering the FA/MNS work in other parts of the building from the electrical work. The intent of the staggering of work phases is to allow one project construction team to cycle through a space with the other following after. The partial overlap of the phases implies that work can be completed by floor in the East

Wing and East Court buildings for the initial phases of this FA/MNS construction project, consolidating disruptions to Museum operations during these two phases.

Most work will take place after-hours.

2.3.8 Commissioning

The system will be commissioned in accordance with NFPA 3, Standard for Commissioning of Fire

Protection and Life Safety Systems, which outlines procedures, methods and documentation of the fire alarm system and its interconnections with other building systems, including, but not limited to BAS. Commissioning of other building systems is not within the scope of this project.

Commissioning will verify that the Fire Alarm System conforms to the Owner’s Project

Requirements (OPR) document (provided by SI) and fulfills design criteria set forth in the final contract documents. Commissioning will also draw upon guidance found within the newly published

NFPA 4, Standard for Integrated Fire Protection and Life Safety System Testing.

35% Submission Update:

Testing and commissioning requirements were further developed and defined during the 35% DD

Phase, with the following decisions made:

EC will develop test procedures to be performed by contractor

The scope of work includes testing to confirm the fire alarm signal reaches the BAS, but does not include confirming the systems/equipment controlled by the BAS are functioning as intended, or correcting those conditions

The different types of testing required for this project were clarified:

o Pre-Testing:

PAGE 2-8 SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM

Testing to ensure that equipment will continue to do what it did before the renovation

This does not include confirming or correcting the systems/equipment controlled by the BAS o Acceptance Testing:

Testing every detector/device after installation

Please refer to the Fire Alarm section of this report for additional information.

Backcheck Submission:

A NICET certified technician shall perform all testing in accordance with the requirements of NFPA 72, NFPA 3, and NFPA 4. A report documenting the procedures and results shall be developed by the NICET technician performing the testing. OSHEM shall approve procedures before testing begins and shall witness testing. Coordinate all testing times and dates with OSHEM personnel. Since a report of the testing will be documented by the NICET technician, commissioning scope will not be required.

2.3.9 Space for New System Components

Most new fire alarm panels will be located adjacent to existing panels. Where space is not available, the design team will propose alternate locations for review and approval by the project stakeholders. Components of the MNS, such as amplifiers, are determined by the number of speakers provided in a particular space. The quantity of amplifiers (and the associated power draw) will not be finalized until the number of speakers is established. Space requirements will be coordinated throughout the design process.

35% Submission Update:

Locations for all new nodes have been identified and vetted based on building surveys and coordination with the project/building stakeholders and are indicated in the drawing package.

Please refer to the Fire Alarm section of this report for additional information.

3.1 ARCHITECTURAL AND HISTORIC PRESERVATION CONSIDERATIONS

To provide audible mass notification throughout the Natural History Building, it is necessary to locate a series of speakers throughout numerous historic spaces, which by their nature are not amenable to inconspicuous speaker placement or distribution of low voltage wiring in conduits.

Finishes in the Rotunda, Ocean, Mammals and Fossil Halls, and other historic spaces consist of stone, plaster and other hard surfaces that prevent the installation of recessed speakers and devices, and concealed wiring and conduit. As the most historically significant spaces in the building, these areas require sensitive placement of speakers within the space and carefully considered pathways for distribution of wiring in conduit to serve the mass notification speakers.

Due to reverberation in spaces like the Rotunda, numerous speakers are required throughout the space at defined intervals both horizontally and vertically to achieve the required intelligibility of the mass notification system. Hard surfaces throughout the spaces pose significant acoustical challenges. Please refer to section 6 Acoustics for additional information.

During the initial phases of the feasibility study, the design team prepared acoustical models of the historic spaces to determine the number of speakers necessary to achieve the required intelligibility. These initial studies intentionally did not take into account the realities of historic building fabric or the historic preservation goals of the building, but rather focused on establishing a baseline for the quantity of speakers required for intelligibility. It was understood that concessions for intelligibility would be required in acoustically challenging historic spaces, subject to SI/OSHEM approval, and that decisions on acceptable speaker quantities/intelligibility would be made as part of the future design efforts of this project. These spaces include, but are not limited to:

Rotunda

Constitution Avenue Lobby (North Lobby)

Ocean Hall (double height area)

Mammal Hall (double height area)

Fossil Hall (double height area)

West Court

East Court

Baird Auditorium

To address historic preservation concerns and establish guidelines for the future design work, members of the design team met with project stakeholders from NMNH, Smithsonian Institution

Historic Preservation and Smithsonian Facilities to walk the historic spaces of the building and discuss the challenges and expectations on site. The goal of the walkthrough was to gain a better understanding of the existing spaces and conditions to better balance intelligibility with historic preservation requirements.

SI tasked the design team to consider creative speaker placement throughout the historic spaces in a manner that maximized intelligibility while remaining sensitive to the building's historic fabric.

The following guidelines were established for future placement of speakers, devices and wiring/conduit distribution:

Removal of historic building fabric (plaster moldings, ceilings, etc.) is not permitted

Devices should be located on perimeter walls, cases and millwork, and their visual presence minimized to the greatest extent possible

Any new elements should be distinctively discernable from the historic building fabric

Speaker wiring must be in conduit; exposed, visible conduit runs are not acceptable in any public spaces

There are opportunities for concealing conduit runs along ledges and cornices/moldings

PAGE 3-2 SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM

In permanent galleries, some devices may require placement in exhibitory; coordination with Exhibits is required

In the main halls, devices may be placed on columns, which are spaced 18’-6” on center

The mid-level cornice within the main halls is frequently utilized for theatrical lighting and may provide a suitable location for speakers and conduit runs

Speakers/devices may be located on free-standing “pylons” adjacent to building columns;

free-standing elements in open areas are not permitted due to conduit trenching requirements

Spaces within the Rotunda and the adjacent ambulatories are the most historically significant spaces in the building. Locating devices in plaster ceilings, stone walls and columns is not permitted.

Integration of speakers and signage elements may be considered; a comprehensive review and holistic approach to building signage would be required

The sprinkler system is distributed through the ambulatory space around the Rotunda; the mass notification system conduit may take a similar pathway

Risers are located in the support spaces flanking the south entrance and may provide a vertical pathway between the Rotunda ambulatory floors

The following preliminary concepts below were developed and included in the feasibility study.

These concepts and others will be further refined and considered as part of the future design phases.

35% Submission Update:

Device integration into public and exhibit space was further explored in the 35% Design

Phase. A key emphasis was to avoid device interface with historic fabric where installation of devices is not 100% reversible. In spaces like the Rotunda and the North

Lobby where stone and marble are prominent architectural features, devices which would require drilling or demolition of any material will not be permitted. Adhering to these surfaces, which could permanently change the material over time, is also prohibited.

Devices may be mounted on historic plaster surfaces as needed. Where required, mounting to flat plaster, which can easily be repaired if the device is ever removed, is permitted. Destruction of ornate plaster, although repairable, should be avoided to the greatest extent possible. When located on plaster surfaces, devices should be tucked away as much as possible and painted to match adjacent surfaces to visually recede as much as possible.

Historic plaster throughout the building is typically located on terra cotta masonry units.

Channeling through the plaster and terra cotta in public spaces to install new pathways, so that they may be concealed, has been deemed destructive and will not be permitted.

Exposed pathways in historic public spaces can be located in square profile wiremolds and be surface mounted. The use of a square profile is critical to allow surface mounted pathways to blend into the historic architecture and make necessary 90 degree turns.

Pathways to end devices in public spaces must meet Survivability Level 1 requirements and do not require a fire rating in a sprinklered building. Pathways should be as high as possible typically and painted to match adjacent surfaces. There are precedents for this installation strategy in various portions of the Rotunda.

The newly developed architectural drawings for the 35% Submission include floor plans for all levels of the building. Device locations will be finalized moving into the 65%

Design Phase. The plans will be utilized to clearly illustrate new pathways, particularly exposed ones, and to better understand the impacts and requirements for installation within historic fabric. In addition, reflected ceiling plans for all public and exhibit spaces have been developed to better understand the impact to existing ceilings when replacing and or adding new devices. This will be a valuable tool to minimize working above collections, which the design team understands should be avoided to the absolute greatest extent possible.

Rotunda: Signage/Speakers Integration

This concept combines the mass notification speakers with building signage with varying degrees of integration. Figure 1 indicates speakers directly affixed to the bronze signage support armature.

This option represents the lowest level of integration between the signage elements and the speakers. Figure 2 indicates a series of speakers “boxed” into the signage with matching speaker fabric to visually integrate the speakers with the signage sy1stem. Figure 3 indicates integration of the speakers with the signage. This concept considers printed speaker fabric as the signage surface, fully concealing the speaker within the sign. In all instances, wiring could be distributed through the bronze framing elements, and tie back to distribution pathways which will be determined during design.

35% Submission Update:

During the 35% design phase, the design team modeled the acoustical characteristics of the Rotunda, one of the most acoustically challenging spaces in the museum, to develop a strategy for an intelligible mass notification system. Building on the signage concept developed in the BOD Report, line array speakers were placed into new signage elements to test their effectiveness. The design team concluded the most effective placement of speakers was in signs located on the north side of the Rotunda directing sound south towards the entry. Speakers located on the first, second, and third floors on the north side of the Rotunda provided a greater-than-expected intelligibility. Please refer to the updated Acoustic section for more information. While speakers are only required on the north side of the Rotunda for audio clarity, the design team recommends

EWINGCOLE | NMNH UPGRADE FIRE ALARM PANELS & MASS NOTIFICATION SYSTEM SF PROJECT NO. 1700103 | EC PROJECT NO. 20190447 | © EWINGCOLE 2021 PAGE 3-5 replacing all Rotunda facing signage to give a uniform appearance. This is critical for first impressions of visitors arriving at the primary Museum entrance located off the

National Mall.

In addition to providing audio for the Rotunda, the placement of speakers in the north

Rotunda signage allows audio to spill over into the adjacent ambulatory circulation spaces. Sound in the ambulatory spaces can be boosted by careful placement of additional line array speakers, as well as floor facing speakers located at the main exhibit entry points. To facilitate installation of exhibit entry speakers, the design team has developed a new exhibit canopy entry signage element.

Please reference the Architecture drawings for drawings related to the updated signage concepts for the Rotunda and Ambulatory space.

65% Submission Update:

The 65% Submission phase refined the number of speakers that are required in the

Rotunda. To achieve intelligibility, the total number of line array speakers in the Rotunda has been reduced as well as restricted to just the first floor. Speakers are still distributed in the ambulatory signage elements as well as adjacent to vertical circulation.

100% Submission Update:

The design team worked to reduce visible wiremold in the Rotunda and adjacent spaces.

To do this new line array speakers speaker locations were added while speakers were removed from Ambulatory signage to avoid unsightly pathways.

The development of the Evan’s Gallery support structure proved to be more visually intrusive than originally thought. Installation of the structure would also interrupt daily activity much more than originally thought. For this reason, the structure was removed from the project and was replaced will wall mounted speakers on the west wall of the hall.

Historic Halls: Free-standing Pylon/Sign Post Concept

This concept combines the mass notification speakers with free-standing elements such as a pylon or sign post within exhibit spaces (see Figure 4). The pylon concept may include an informational or exhibit video display. Similarly, the sign post concept may integrate lower-level building or exhibit signage. Either placement could be supplemented speakers on the mid-level cornice, near the theatrical fixtures in Figure 4.

35% Submission Update:

Design workshops in the 35% design phase explored possibilities for locating speakers in exhibit spaces. With input from the museum, it was decided that locating devices on building fabric is preferential to locating devices in exhibit elements. This both minimizes interface with exhibits now, and avoids similar work in the future as various exhibit elements are updated over time. While it may not be feasible to avoid locating devices in exhibits entirely, it should be minimized to the greatest extent possible.

Device placement for the 35% Submission prioritizes location on building fabric with a majority of devices located in the ceiling. To illustrate and better understand the location and impact of these new devices, reflected ceiling plans have been developed for all the exhibit spaces in the museum and are located in the Architecture section of the 35% drawing package. Where possible, devices have been located in accessible ceilings. Key interior elevations have also been developed to illustrate device locations where ceiling locations are not possible or effective.

Rotunda: Exhibitory Integration

This concept integrates mass notification speakers within exhibitory. Figure 5 below indicates speakers within one of the darker bands of stone in the Rotunda Elephant base. Another option for consideration may include rock elements with built-in (concealed) speakers on the Elephant platform itself. Any proposed integration with exhibit elements would require careful collaboration and coordination with Exhibits staff as part of the future design efforts.

Given the effectiveness of line array speaker integration into Rotunda signage elements, this approach is no longer under consideration.

4.2 EXISTING CONDITIONS AND CONFIGURATIONS

The National Museum of Natural History (NMNH) is equipped with a Siemens MXL fire alarm (FA) system. The system is an electrically supervised, manual and automatic, annunciated fire alarm and detection system. While most of the panels and programming throughout the building are Siemens MXL, some of the devices and fire alarm components are legacy equipment from older systems, such as the Siemens System 3 FA System. Additionally, in a recent renovation of West Court, a new Siemens DESIGO MODULAR System was installed and serves as the main FA system for this area of the building.

In general:

The building is fully detected. The type of detection present throughout the facility is inconsistent. Both addressable and conventional detectors are present.

Notification and initiating devices installed throughout the building are also inconsistent. Devices vary in color and model. The master plan assumes that the building will be brought up to current code with respect to smoke detection, fire alarm notification and initiation.

More recent installations throughout the building include notification booster panels to accommodate the increased power draw incurred by the increased presence of strobes. These booster panels, and in some cases the strobes, can be retained.

Except for some of the newer installations, existing conditions did not appear compliant with current code requirements, particularly regarding requirements for notification and intelligibility.

Existing Panel / Node Information:

The Fire Alarm system is currently a network consisting of a combination 16 MXL and DESIGO MODULAR nodes or DGPs. A total of 3 subpanels, also known as PSRs or MXLR DGPs, are also present within the building. The subpanels are tied into the main panels on Nodes 1 and 4, both of which are MXL panels. Approximately 35 terminal cabinets are also present throughout the building and are connected to the different nodes of the system.

The general zones served by each node are shown in plan in Appendix A. A riser diagram of the current configuration of the nodes and connections between nodes can be found in Appendix B.

Additionally, existing conditions drawings are shown in Appendix C.

65% Submission Update

The general zones served by each node, as well as all riser diagrams and existing conditions drawings can be found in the Fire Alarm Drawings included as part of this submission. Separate appendices will not be provided.

Existing Node 1:

Node 1 is located in the OPS Security Control Room on the ground level in the west hall of the main building. There are several other pieces of FA equipment in this space, including but not limited to: two (2) Network Command Centers (NCC) (one connected to the MXL system and one connected to the DESIGO MODULAR system), smoke control panels, booster panels, power supply / battery enclosures, terminal cabinets, and Nodes 14 and

17. The NCC is the main computer and user interface for the entire Siemens FA system installed throughout the building. The NCC is used to manage networked fire panels and allows its users to manage and control network nodes from a central location. The NCC for the DESIGO MODULAR system may potentially be upgraded with Siemen’s DESIGO software to integrate FA, MNS and other building systems more seamlessly. This software will be described in more detail in the MNS section of the report.

Node 1 has direct interface with the Building Automation System (BAS) within the panel enclosure. Additionally, an Audio Control Module (ACM-1) card and 26 switches for audio control are found within the panel. The ACM-1 currently has no back-up as Siemens is no longer producing or manufacturing this card; thus, the system has the potential to have a single point failure.
