Gamewell FCI ATD-L3H-IV Hi-Temp (190F) Heat Detector

The Gamewell FCI ATD-L3H-IV is a Velociti Series 3 intelligent addressable thermal detector that provides fixed high-temperature heat detection at 190°F (88°C) and 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 high-temperature 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 135°F (-20°C to 57°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.
