Gamewell-FCI ATD-L2F Heat Detector

The Gamewell-FCI ATD-L2F is a commercial heat detector designed for compatible Gamewell-FCI Velociti® fire alarm systems. It utilizes an advanced thermistor sensing circuit to provide dependable 135°F (57°C) fixed-temperature heat detection for commercial and industrial fire alarm applications.

The detector features Velociti® communication, rotary decimal addressing, dual bi-color status LEDs, and a low-profile plug-in design for simplified installation and maintenance. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Fixed-temperature heat detection
• 135°F (57°C) thermal activation
• Reports alarm conditions to the fire alarm control panel
• Individual device identification
• Continuous detector supervision
• Dual bi-color LED status indication
• Magnetic functional testing
• Automatic maintenance monitoring

Electrical & System Information

The ATD-L2F operates on compatible Gamewell-FCI Velociti® Signaling Line Circuits (SLC) and communicates directly with compatible addressable fire alarm control panels. The grouped polling communication protocol provides faster response times while maintaining reliable supervision of every detector on the signaling loop.

The detector uses rotary decimal address switches for local addressing and installs on compatible detector bases, allowing quick replacement or servicing without disturbing field wiring.
