FORT PIERCE ENGINEERING, INC. IRC Maintenance individual alarm inputs or normal system responses (outputs) for alarms, without changing the system's executive programming or affecting operation of the rest of the system. How to do this must be included in the training required to be given to the owner's designated personnel (see 8 .6), and must also be part of the written documentation provided by the fire alarm equipment supplier. 1 .5 A Fire Alarm Control Unit (FACU) is required and shall be located in the reception area of the main building. Consult with the local fire official prior to precisely locating the FACU. 1 .6 The FACU and all other control equipment locations, including any transponders, sub-panels, and booster power supplies, must be protected by a spot type smoke detector located within 15 feet of the equipment (measured horizontally). 1 . 7 A supervised "AHU Shutdown Defeat" switch must be provided in/adjacent to the FACU or as a key-operated function in the Remote Annunciator (if provided). The switch must cause a system "trouble" indication when it's placed in the off-normal (" Shutdown Defeated") position. 1 . 8 Reserved. 1 .9 Reserved. 1 . 10 The fire alarm system must include an LED-type "zone" annunciator at (or in) the FACU, or in another location if acceptable to the AHJ. As a minimum, this annunciator is to indicate the specific type of alarm or supervisory signal (smoke detector, waterflow, sprinkler valve closed, etc.), for groups of devices. The facility shall, at a minimum, be divided into the following zones: 1 ) Office Building West; 2) Office Building East; 3 ) Office Building Ducts ; 4)Maintenance Building; 4) Storage Bays 1 . 11 Alarm notification appliances (audible and visible) are to comply with NFPA 72 and the Florida Building Code for intensity and placement. The audible evacuation signal shall be the ANSI S3 .41 three-pulse temporal pattern. All strobe lights installed in a single space must be synchronized. Contact the AHJ for additional information or to seek approval of any alternative design. 1 . 12 Alarm notification appliance (NAC) circuits shall be NFPA 72 Style Y (Class B). The load connected to each circuit must not exceed 80% of rated module output and the coverage of each circuit in the main building shall not exceed half of the main building. The NAC voltage drop during alarm must not exceed 14% of the voltage measured across the batteries at that time. To achieve this, the design must consider wire size, length of circuit, device load, inherent voltage loss within the FACU's power supply, etc. The contractor shall use power outage testing to verify that the NAC circuit was designed and installed properly. 1 . 13 The following protection against voltage transients and surges must be provided by the fire alarm equipment supplier, and installed by the electrical contractor: On AC Input: A feed-through (not shunt-type) branch circuit transient suppressor such as the EFI E100HW120, Leviton 51020-OWM, Emerson/Northern Technologies TCS-HWR, Transtector ACPIOOBW series, or any equivalent UL 1449 - 2nd Edition Listed device submitted to and 16965 FIRE DETECTION & ALARM SYSTEM Page 3 OF 10
