Gamewell FCI ATD-L3-IV 135F Heat Detector (Ivory)

The Gamewell FCI ATD-L3-IV is a Velociti Series 3 intelligent addressable thermal detector with 135°F (57°C) fixed-temperature heat detection, built as an ivory service model that supports both Velociti and CLIP protocol on the 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 activated by an external magnet. Key Specifications: Type: Intelligent addressable thermal detector Core Function(s): Monitors temperature and reports fixed-temperature heat alarm conditions to the fire alarm control panel Loop/Protocol: Velociti SLC; Velociti and CLIP (legacy service model) 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-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 for B300-6 base System Compatibility: Works with E3 Series and S3 Series intelligent fire alarm control panels that support Velociti and CLIP protocol on the SLC loop.
