Gamewell FCI ATD-L3 135F Heat Detector (White)

The Gamewell FCI ATD-L3 is a Velociti Series 3 intelligent addressable thermal detector that provides 135°F (57°C) fixed-temperature heat detection 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 thermal alarm conditions to the fire alarm control panel Loop/Protocol: Velociti SLC (ATD-L3 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 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 B200S-WH – Bright White, intelligent addressable programmable sounder base B224BI-WH – Bright White, isolator detector base B224RB-WH – Bright White, relay detector base RA100Z – Remote LED annunciator (3–32 VDC); for use with B501 and B300-6 TR300 – Accessory flange ring for B300-6 base, bright white System Compatibility: Compatible with Gamewell-FCI E3 Series and S3 Series intelligent fire alarm control panels when the SLC is configured for Velociti protocol; GWF-7075 supports Velociti only.
