FORT PIERCE ENGINEERING, INC. IRC Maintenance (duct-seal), to prevent condensation from infiltrating humid air. 6 .5 There shall be no splices in the system other than at device terminal blocks, or on terminal blocks in cabinets. "Wire nuts" and crimp splices will not be permitted. Permanent wire markers shall be used to identify all connections at the FACU and other control equipment, at power supplies, and in terminal cabinets. 6.6 If building layout requires the terminal cabinet to be above a drop ceiling, its location must be clearly and permanently identified with a placard readable from floor. Terminal block screws shall have pressure wire connectors of the self-lifting or box lug type. 6. 7 Initiating device circuits shall be wired with type FPL/FPLR/FPLP fire alarm cable, AWG 18 minimum, low capacitance, twisted shielded copper pair. Cable shield drain wires are to be connected at each device to maintain continuity, taped to insulate from ground, and terminated at the FACU . Acceptable cables include Atlas 228- 18- 1 - 1STP, BSCC S1802s19 (same as EEC 78061,C), West Penn D975, D991 (AWG 16), D995 (AWG 14), or equal wire having capacitance of 30pf/ft. maximum between conductors. Belden 5320FJ acceptable if only FPL rating needed. The cable jacket color shall be red, with red (+) and black (-) conductor insulation. In underground conduit, use Type TC or PLTC cable (PE insulated) to avoid problems from moisture. Minimum conduit size of any type is 1/4 inch. 6.8 Reserved. 6. 9 Except as required by 2. 8 and 6.7, all other circuits in the system shall be wired with AWG 121 stranded copper, THHN/THWN conductors, installed in minimum 3/4 inch conduit. Color code as shown below throughout the system, without color change in any wire run: • Alarm notification Appliance Circuits (homs/strobes). . . . . .Blue (+)Black (-) • Separate 24vdc Operating Power (for equipment) . . . . . . . . . . . . Yellow (+)Brown (-) • Circuits from ZAM's to Monitored Devices (AWG 14/ 16). . .Violet(+)/Grey (-) 6. 10 Notification Appliance Circuit booster ("ADA") power supplies must be individually monitored by the FACU and protected by a smoke detector per NFPA 72 . They shall not be located above a ceiling, or in non-conditioned space. 6. 11 All junction boxes shall be painted red prior to pulling the wire. Those installed in finished areas are permitted to be painted outside to match the finish color. 6. 12 The branch circuit breaker supplying the system must be physically protected by panelboard lock or handle lock and each must be identified with a 1 /4" permanent red dot applied to handle or exposed body area. The breaker supplying the system shall also be clearly and conspicuously identified on the electric branch-circuit panel schedule and electrical as-built drawings . 6. 13 Provide an engraved label at each fire alarm system control unit, system sub-panel or data gathering panel, supplementary notification appliance (SNAC) panel, digital alarm communicator, etc., identifying its 120vac power source, as follows: Panelboard location, panelboard identification, and branch circuit number. 6 . 14 The fire alarm system shall monitor 120vac power to shunt trip breakers used in conjunction with 16965 FIRE DETECTION & ALARM SYSTEM Page 7 OF 10
