Gamewell-FCI ATD-HL2F Fixed Temperature Heat Detector

The Gamewell-FCI ATD-HL2F is a commercial heat detector engineered for compatible Gamewell-FCI Velociti® addressable fire alarm systems. It provides dependable 190°F (88°C) fixed-temperature thermal detection for applications where elevated ambient temperatures make standard heat detectors unsuitable.

Designed for reliable operation in demanding commercial environments, the detector features rotary address switches, dual LED status indicators, plug-in installation, and continuous communication with the fire alarm control panel for supervision and alarm reporting. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Fixed-temperature heat detection
• 190°F (88°C) thermal activation
• Individual device identification
• Alarm reporting to the fire alarm control panel
• Continuous electronic supervision
