· The SOW mentions a fire alarm panel that monitors the fire sprinklers, but is vague on the system. Does this job require an actual fire alarm system with strobes and horns? And, does this system require a MASS notification?

Fire Alarm and Mass Notification System - A new combination fire alarm/mass notification system will be provided in accordance with NFPA 72, UFC 4-021-01, and UFC 3-600-01. The fire alarm/mass notification control panel (FMCP) will be in a location approved by the Base Fire Department in a conditioned space in the building. Initiating devices will consist spot-type photoelectric smoke detectors (above the FMCP and other fire alarm panels), manual pull stations at the exits, control valve tamper switches and sprinkler waterflow switches. Photoelectric duct smoke detectors will be provided in the supply ducts of air handling units with capacities greater than 2,000 cfm. The sprinkler system tamper switches will be monitored as supervisory conditions by the fire alarm/mass notification system. The fire alarm/mass notification system will monitor the fire pump system for the following conditions: fire pump running; fire pump loss of power; fire pump phase reversal. All SLC, IDC and NAC wiring in unfinished areas, including above ceilings, will be Class B and in red conduit per UFC 3-600-01.

All SLC, IDC and NAC wiring in finished areas will be Class B, in conduit painted to match the room finish and provided with red bands every 20 feet per UFC 3-600-01. A fire alarm remote annunciator will be provided in a location approved by the Base Fire Department. Alarm, supervisory and trouble conditions will be transmitted to the Base Fire Department via an integral DACT.

The fire alarm/mass notification system will be compatible with the Base-wide MNS system. Surge protective devices will be provided for each control panel and auxiliary panel.

Combination speaker/strobes, speakers and strobes will be provided in accordance with NFPA 72. The system will be designed in accordance with UFC 04-021-01, including live voice messaging and playback of prerecorded messages. LED text signs will be provided above each egress door. Weatherproof exterior speakers will be provided at exterior gathering locations and entrances/exits to the buildings. The autonomous control unit (ACU) will form a combined unit with the fire alarm/mass notification panel. Local operator consoles (LOC) will be provided as directed by the responsible fire protection engineer. An interface with the fire alarm system will be provided to silence the fire alarm voice messages during broadcast of mass notification messages.
