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.
