This work includes designing and providing a new, complete, fire alarm and mass notification (MNS) system with radio transceiver as described herein and on the contract drawings for buildings 2405 and 2406 on Joint Base Charleston Naval Weapons Station Goose Creek, South Carolina. The system shall provide “point reporting” to the Monaco D-21 Central Receiving station. Include system programming, wiring, raceways, pull boxes, terminal cabinets, outlet and mounting boxes, control equipment, initiating devices, notification appliances, supervising station, fire alarm transmitters/mass notification transceiver, and other accessories and miscellaneous items required for a complete operational system even though each item is not specifically mentioned or described. Provide systems complete and ready for operation. The new system shall be compatible with the existing Monaco D-21 Central Receiving Station without the use of interfacing relays and shall provide “point reporting”. There are gas-fired dryers as noted in room E102 in the as-built drawings in each building. Design and installation must comply with UFGS 25 05 11, UFC 4-010-06 and AFGM 2019-320-02.

b. Each remote fire alarm control unit must be powered from a wiring riser specifically for that use or from a local power panel located on the same floor as the remote fire alarm control unit. Where remote fire control units are provided, equipment for notification appliances may be located in the remote fire alarm control units.

c. The fire alarm and mass notification system must be independent of the building security, building management, and energy/utility monitoring systems other than for control functions.

d. Provide demolition and disposal of any existing devices and all wiring for each wing under construction. Provide demolition and disposal of any exposed conduit system that are not re-utilized. The contractor shall be responsible for patching, priming and spot painting of any areas affected by demolition.
