Design Requirements
- Fire alarm panels, transceivers, and other sensitive electrical or electronic equipment shall be installed in dedicated electrical equipment rooms readily accessible to maintenance personnel independent of building occupants (i.e., space accessible from exterior of facility), not in mechanical spaces or other areas subject to excessive temperature and moisture.
- Minimum conduit size for all fire alarm and detection is 3/4 inch.
- Duct smoke detectors generally should only cause the AHU it serves to shut down and cause a supervisory signal to be announced at the FACP and be transmitted by transceiver. A general alarm condition at the FACP should not cause a global shut down of the H.V.A.C. system unless required by code as part of a smoke control system. ATFP requirements for global shut down of the H.V.A.C. system shall be accomplished via mushroom switch. All AHU's and H.V.A.C. systems that are shut down by duct smoke detectors, fire alarm conditions, or ATFP switches shall auto restart when the condition that caused the shutdown is cleared or reset. Manual reset of H.V.A.C. systems is not acceptable.
- All designs shall be reviewed, approved, stamped, and signed by the Fire Protection Specialist prior to submitting for government approval.
- Preliminary and Final Acceptance Testing shall be witnessed by the Fire Protection Specialist. The USACE representative and/or DPW representatives shall be invited to attend and witness, but are not required to be present.
- Final acceptance testing must be scheduled 7 to 10 days prior to day of testing.
- Smoke detectors shall be of the photo-electric type wherever possible, ionization type detectors will only be used where alternative detectors are not available or unsuitable for specific applications. Manufacturers of ionization detectors specified must provide for no cost disposal of their detectors.
- Addressable fire alarm panels shall display history of events on the panel display without additional software/hardware.
- Notification appliances in individual sleeping rooms of dormitories that sound with the general alarm shall silence with the general alarm silence function from the fire alarm panel.
- When device is mounted externally on brick or exterior surface, a rubber gasket shall be used (to reduce electrolysis and grounds). Conduit penetrations in the top of exterior mounted devices is not acceptable.
- All conduit penetrations shall be through the sides of transceiver enclosures, do not penetrate transceiver enclosures on top or bottom.
- All fire alarm transceivers must be listed or approved for use with the existing Monaco D-21M base reporting system.
- All threaded connections on the antenna mast shall have silicone seal added for water proofing the joint.
- Spare parts, manuals for fire alarm system, documentation showing mapping/tree of devices (showing the polling sequence), and all software/hardware required for programming/editing shall be turned over to JBLM DPW personnel at the time of project closeout. For software-based systems, a record copy of the site-specific software will be delivered to the JBLM Fire Alarm Shop after all changes have been made from acceptance testing.
- When warranty is in effect, the Fire Alarm Contractor shall be required to respond (physically go to building in Alarm or Trouble), within 48 hours to an ALARM CONDITION and 72 hours to a TROUBLE CONDITION.
- Fire Alarm Remote Annunciators are not desired as part of the fire alarm system on JBLM unless specifically required by code.
Notes to Designers on Drawing Content
- All as-builts shall be required to show the sequence of operation table, details of the different devices and the external wiring connections, exact run of conduit, quantity of wires, wire color code, location of every initiating device, signaling device, module, and any major junction boxes or power supplies. The plans will also show Loop number and the address of each device, or module, if system is addressable.
- A copy of the record drawings (as-builts) shall be delivered to the DPW Fire Alarm Techs at the initial fire alarm acceptance test.
