About this file
This document is a Fire Alarm Replacement Narrative and technical design specification for Buildings 220, 221, 223, and 225 at the National Institute of Standards and Technology (NIST), prepared by CFR Engineering Consultants, Inc. The narrative outlines the complete demolition of existing fire alarm systems and installation of new addressable fire alarm systems compliant with NFPA 72 standards. The project includes a fully integrated, electrically supervised fire alarm and detection system featuring both manual and automatic operation with annunciation throughout all buildings. Notification will be provided through speakers meeting NFPA 72 intelligibility requirements and multi-candela, UL 1971-compliant strobes. The new fire alarm control panels (Simplex 4100ES) will be installed at the main entrance of each building with a transponder panel in the attic, serving various circuits within sub-basements, basements, first, second, and third floors. The system must be fully installed, approved, tested, and operational before removal of existing systems.
The design incorporates extensive circuit performance requirements including Class A signaling line circuits, Class X panel-to-panel communication, and Class A notification appliance circuits using 70V RMS amplifier circuits. Separate circuits are specified for strobe and speaker devices on each level and spine, as well as separate signaling line circuits and exterior speaker circuits. Initiating devices include photoelectric smoke detectors (where required by code), heat detectors throughout each building, and manual pull stations positioned to ensure all occupants can reach a station within 200 feet of travel distance. The narrative includes detailed audibility and intelligibility calculations using EASE Evac acoustic modeling software for multiple room configurations across the four buildings, demonstrating compliance with NFPA 101 and NIST standards. All design must be reviewed and approved by the NIST Authority Having Jurisdiction with an approved NIST-383 form prior to construction commencement. The contract reference is 133ND21DNB190025, Task Order 133ND24FNB190117, with a submission date of August 29, 2025.

FIRE ALARM AND MASS NOTIFICATION SYSTEM
The existing fire alarm systems in Buildings 220, 221, 223, and 225 will be demolished. A new, addressable fire alarm system, compliant with NFPA 72, will be installed to notify occupants inside the buildings. This system will be a fully integrated, electrically supervised, addressable, intelligent fire alarm and detection system, featuring both manual and automatic operation, with annunciation throughout the buildings.
Buildings 220, 221, 223, and parts of 225 are not equipped with sprinkler systems. Automatic detection will be provided throughout each building to provide total coverage. The system will notify building occupants through a combination of speakers and strobes. These speakers will meet
NFPA 72 standards, including intelligibility requirements. The mass notification system will provide audible messaging both within the buildings and via exterior speakers located at exits and key outdoor areas where personnel may be present.
A new fire alarm control panel (FACP), specifically the Simplex 4100ES, will be installed at the main entrance of each building. This FACP will be compatible with the existing fire alarm reporting loop. The system will include a battery backup power supply with sufficient capacity to operate under quiescent conditions, and in the event of an emergency, it will maintain functionality during fire or other emergency situations.
FIRE ALARM DESIGN
General
All fire protection devices, equipment, and materials shall be listed for their intended use in accordance with FM Global and/or Underwriters Laboratories (UL) standards. Unless otherwise specified, each floor of every building will be covered by a single fire alarm zone.
The new fire alarm system must be fully installed before the demolition of the existing system. All new fire alarm systems must be approved, tested, and fully operational prior to the removal of the existing systems in each building.
NIST shall be given the option to salvage any existing fire alarm devices slated for demolition before they are disposed of.
Control Panels
All buildings will be provided with a 4100ES FACP located in the first floor lobby (serving circuits within the sub-basement, basement, first floor, and second floor) and a 4100ES transponder panel located in the Attic (serving circuits within the third floor, attic, and penthouse).
August 29, 2025
Circuit Performance
Fire protective signaling systems shall have the following circuit performance in accordance with
NFPA 72:
• All signaling line circuits (SLCs) shall meet Class A requirements.
• All panel-to-panel communication shall meet Class X requirements.
• Initiating device circuits (IDCs) serving more than one device shall meet Class A requirements. IDCs serving only one device, such as an IDC from a monitor module to an adjacent waterflow alarm, may meet Class B requirements.
• All notification appliance circuits (NACs) shall meet Class A requirements. All fire alarm notification circuits shall use a 70 v RMS amplifier circuit.
Fire alarm circuits shall be provided as follows:
• Separate Strobe Circuits for Each Level.
• Separate Strobe Circuits for Each Spine.
• Separate Speaker Circuits for Each Level.
• Separate Speaker Circuits for Each Spine.
• Separate SLC Circuits for Each Level.
• Separate SLC Circuits for Each Spine.
• Separate Exterior Speaker Circuits for Each 1st Level and Penthouse Level.
• Separate Acoustic Hailing Device (Loudspeaker) Circuit for Each 1st Level.
• Separate M&E Circuit for Each Panel.
Notification
Notification shall be via speakers and strobes. Spacing and location of speakers and strobes shall be compliant with the ABA (Architectural Barriers Act), NFPA 72, NIST O/P 7400 and NIST S
7401. The quantity and location of interior speakers shall be determined by the audibility requirements. For voice systems, additional speakers tapped at lower wattage provide greater intelligibility.
Visual signals shall be provided via multi-candela, field selectable strobe lights utilizing high-intensity, white xenon flash tube with a clear plastic lens. The body of the strobe shall be white in color marked “ALERT”. All strobes shall be UL 1971 compliant as well as ABA compliant.
August 29, 2025
Notification devices shall be installed in locations required by NFPA 101 and NFPA 72 and NIST
7401 and meet audibility/intelligibility requirements. See Appendix for audibility and intelligibility calculations. (To be provided at a later submission)
Initiating Devices
Fire alarm initiating devices shall be provided in accordance with NFPA 101 and NFPA 72 except as modified herein.
• Smoke detectors shall only be installed as required by codes. Only photoelectric smoke detectors shall be utilized.
• Heat detectors shall be provided thoughout each building as required by codes.
• Duct detectors shall only be installed as required by codes or referenced herein.
• All automatic detection devices shall be clearly labeled and access shall be provided for testing and maintenance.
• Manual pull stations shall be required at all exits and so that all occupants can reach a pull station within 200ft of travel distance.
PERMITTING REQUIREMENTS
All design must be reviewed and approved by the NIST AHJ, and no work shall be started without an approved NIST-383 form as required by NIST S 7401.01.
