Gamewell FCI ATD-L3R-IV 135F Fixed/ROR Heat Detector (Ivory)

The Gamewell FCI ATD-L3R-IV is a Velociti Series 3 intelligent addressable thermal detector that provides 135°F (57°C) fixed-temperature and rate-of-rise heat detection, and it supports both Velociti and CLIP protocol on the SLC loop for legacy installations. It uses rotary address switches for point ID location (01–159), dual LEDs for 360° visibility, and a built-in functional test switch activated by an external magnet. Key Specifications: Type: Intelligent addressable thermal detector Core Function(s): Monitors temperature and reports fixed-temperature and rate-of-rise heat alarm conditions to the fire alarm control panel Loop/Protocol: Velociti SLC; Velociti and CLIP Power: 15 to 32 VDC from SLC; 200 μA standby @ 24 VDC; 2 mA max alarm current @ 24 VDC (red LED enabled); 4.5 mA max current @ 24 VDC (amber LED enabled) Indicators/UI: Dual LEDs (360° visibility); rotary address switches (01–159); functional test switch activated by an external magnet Operating Range: -4°F to 100°F (-20°C to 38°C) Compatible Bases & Accessories: B300-6-IV – Ivory 6-inch standard flanged low profile mounting base B501-IV – Ivory 4-inch flangeless mounting base B200S-IV – Ivory intelligent addressable sounder base B224BI-IV – Ivory isolator detector base B224RB-IV – Ivory relay detector base RA100Z – Remote LED annunciator (3 to 32 VDC); for use with B501 and B300-6 TR300-IV – Ivory trim ring System Compatibility: Works with E3 Series and S3 Series intelligent fire alarm control panels that support Velociti and CLIP protocol on the SLC loop.
