Fire Alarm System

Per ANGETL, 15-01-03 and UFC 3-600-01, install a sprinkler system and minimize the use of fire detection.

The contractor shall provide complete system including instrumentation and equipment.

System shall be a supervised addressable system with a BTX Monaco Transceiver for communication to the Fire Department, or a M2 Addressable Monaco fire alarm system.

• An automatic fire detection system is required for all new construction, and should be retrofitted into existing buildings. The system shall meet the requirements of NFPA Publications 70 (National Electrical) Code, 72 (National Fire Alarm Code) in accordance with Life Safety code #101 and NFPA Fire Code #1 Prevention.

• An automatic fire alarm system should include both automatic and manual initiation with outside alarm and notification to the base fire station through a MONACO building transceiver. Where four or more zones are required, a graphic annunciator will be provided, subject to location by the base fire department. The system shall be of the addressable type. Automatic detectors shall be the heat detecting type, except for sleeping quarters, exit corridors, and air conditioning ducts.

• Monaco’s D-21 Enhance Radio Alarm System receives fire and utilities signals from protected buildings to a central reporting location, Base Fire Department. The signals are transmitted by radio instead of conventional telephone lines or cable pairs. The use of radio frequencies (Base Fire Department approval needed) as the transmission medium eliminates the need for acquiring, installing and maintaining landlines.

Monaco Fire Alarm Control Panel/Transceiver model M-2 addressable is recommended.

• System Model: BTX Monaco Transceiver. The BTX Transceiver option provides remote automatic and manual control of devices such as civil defense sirens, visual alert lighting systems and any other systems that require activation and deactivation control.

Mass Notification Systems are required for new construction and major renovations per UFC 4-021-01. Selfridge standard for the mass notification system is Simplex 4100 ES.

Communication

Communications The following comments are identified as requirements to be incorporated into all project requirements. They are applicable to A/Es, contractors, and all on-base agencies:

During the programming of SRM projects, the Base Civil Engineer (BCE) shall notify base communications and the regional ANG STEM-B (Systems Telecommunications

82 | P a g e S E L F R I D G E D E S I G N S T A N D A R D S

Engineering Manager) for the acquisition of these Communications funds so they are available at construction award. Design as a separate bid option or additive bid item.

All building-to-building relocations are to be coordinated in advance with 127WG/SC personnel to ensure communications cable is available for the facility and is of sufficient size to provide service for present and projected requirements. Relocations to an existing building that have inadequate infrastructure to meet current or projected communication requirements will necessitate a communications project to install such support as may be necessary, at the customer’s expense. (Local fire regulations require a means of communications before any building may be occupied)

127WG/SC must be involved in the planning and coordination process for all new construction, renovations, and demolition projects. This is to afford communications planners the opportunity to ensure communications requirements are adequate to satisfy customer needs and to protect existing assets. Customer communications needs in this instance means telephones, local area network (LAN) connectivity, paging systems, closed circuit TV (CCTV), fire suppression/ alarm, radio (land mobile and ground to air), and security/alarm systems.

Special Systems and Communications These systems shall include:

• telephone/intercom

• computer/data

• public address

• closed circuit television

• fire suppression/alarm

• Security, etc.

• EMCS

Verify all requirements with:

• Base Communications Officer

• Information Assurance Officer

• Visual Information Manager

• Base Fire Chief

• Security Officer as appropriate, through the Base Civil Engineer.

Telecommunications cabling systems are installed using a Total Network Concept supporting a multi-product, multi-vendor environment. The common thread among all installed equipment is performance specifications and interoperability. All components of telecommunications system such as cabling, patch panels, patch panel cables, connectors, modular jacks, etc., shall be rated with the same level of performance specifications.

The minimum grade of cable and termination hardware to be used within buildings is Category 6 (CAT 6) unshielded twisted pair (UTP) plenum rate when required.

Performance specifications for building wiring will be installed according to building Core rating:

• Core 1 facilities are being designed with three cat 6 cables and one 50m laser optimized multi-mode fiber connections in each receptacle.

• Core 2 and 3 facilities will be designed with four cat 6 connections per receptacle. (See Figure 30 on Core Facility Prioritization.)

Optical fiber may be used when supported mission dictates and or as deemed financially feasible. When Optical fiber is used within the horizontal system, a 50/125u laser optimized 2 strand cable will be used. Laser optimized multimode is defined as having 2 GHz bandwidth in the 850 nm window.

S E L F R I D G E D E S I G N S T A N D A R D S 83 | P a g e

All telecommunications must be tested according to the standards listed at the end of this section. Test results shall be provided to the Base Civil Engineer, Communications Squadron/Flight and Base Contracting Officer in electronic format prior to system acceptance. The test results must represent that the system is in complete working order.

All outside plant telephone cable will be of the PE-39 type and tested per UNITED STATES DEPARTMENT AGRICULTURE Rural Utilities Service Bulletin 1753F-201 (PC-4) upon installation. Electronic test data sheets must be provided to civil engineering showing 100% passing rate. Splices will be complete using 710 splice modules.

Compliance with the following standards is mandatory and applies to all telecommunications installations. Use latest editions of the following references.

• TIA/EIA-568, Commercial Building Telecommunications Cabling

Standard, including attachments and addendums.
