FL 3/16 <br />DIGITAL, ADDRESSABLE FIRE-ALARM SYSTEM 283111 - 6 <br />2. Station Reset: Key- or wrench-operated switch. <br />2.6 SYSTEM SMOKE DETECTORS <br />A. Manufacturers: Subject to compliance with requirements, provide products by one of the <br />following: <br />1. Fire-Lite Alarms, Inc.; a Honeywell International company. <br />2. Gamewell - FCI by Honeywell. <br />3. Notifier. <br />4. Siemens Industry, Inc.; Fire Safety Division. <br />5. Silent Knight. <br />6. SimplexGrinnell LP. <br />B. General Requirements for System Smoke Detectors: <br />1. Comply with UL 268; operating at 24-V dc, nominal <br />2. In first subparagraph below, retain first option for additions to existing four-wire systems <br />or if detector auxiliary contacts are used for critical control functions such as air-handler <br />shutdowns. Otherwise, retain type based on class of initiating-device circuit. Four-wire <br />detectors have power supply wiring separate from the initiating-device circuit wiring. <br />Both power supply wiring and initiating-device circuit wiring must be supervised. <br />3. Integral Addressable Module: Arranged to communicate detector status (normal, alarm, <br />or trouble) to fire-alarm control unit. <br />4. Base Mounting: Detector and associated electronic components shall be mounted in a <br />twist-lock module that connects to a fixed base. Provide terminals in the fixed base for <br />connection to building wiring. <br />5. Self-Restoring: Detectors do not require resetting or readjustment after actuation to <br />restore them to normal operation. <br />6. Integral Visual-Indicating Light: LED type, indicating detector has operated and power- <br />on status. <br />7. Remote Control: Unless otherwise indicated, detectors shall be digital-addressable type, <br />individually monitored at fire-alarm control unit for calibration, sensitivity, and alarm <br />condition. <br />a. Rate-of-rise temperature characteristic of combination smoke- and heat-detection <br />units shall be selectable at fire-alarm control unit for 15 or 20 deg F per minute. <br />b. Fixed-temperature sensing characteristic of combination smoke- and heat-detection <br />units shall be independent of rate-of-rise sensing and shall be settable at fire-alarm <br />control unit to operate at 135 or 155 deg F. <br />c. Multiple levels of detection sensitivity for each sensor. <br />d. Sensitivity levels based on time of day. <br />C. Photoelectric Smoke Detectors: <br />1. Detector address shall be accessible from fire-alarm control unit and shall be able to <br />identify the detector's location within the system and its sensitivity setting. <br />2. An operator at fire-alarm control unit, having the designated access level, shall be able to <br />manually access the following for each detector: <br />a. Primary status. <br />b. Device type. <br />c. Present average value. <br />d. Present sensitivity selected. <br />e. Sensor range (normal, dirty, etc.). <br />D. Duct Smoke Detectors: Photoelectric type complying with UL 268A. <br />1. Detector address shall be accessible from fire-alarm control unit and shall be able to <br />identify the detector's location within the system and its sensitivity setting. <br />2. An operator at fire-alarm control unit, having the designated access level, shall be able to <br />manually access the following for each detector: <br />DocuSign Envelope ID: 40CF07BE-0F08-4B66-B4FD-884A0A07C01C
