Gamewell FCI ATD-L3H Hi-Temp (190F) Thermal Sensor (White)

The Gamewell FCI ATD-L3H is a Velociti Series 3 intelligent addressable thermal detector that provides fixed high-temperature heat detection at 190°F (88°C) on a Velociti SLC loop. It uses rotary address switches for point ID location (01–159), dual LEDs for 360° visibility, and a built-in functional test switch that’s activated with 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 (ATD-L3H is Velociti; the -IV service version is Velociti/CLIP for legacy systems) 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 – Bright White, 6” base, standard flanged low-profile mounting base B501-WH – Bright White, 4” standard European flangeless mounting base.
