Tyco ADT-HFS 135°F Fixed Temperature Heat Detector

The Tyco ADT-HFS Intelligent Fixed Temperature Heat Detector provides addressable thermal detection for compatible ADT/Tyco fire alarm systems. The detector monitors ambient temperature and initiates an alarm when the temperature reaches its 135°F fixed-temperature threshold.

Designed as an intelligent detector, the ADT-HFS communicates its status to compatible fire alarm control equipment for individual point identification. Its low-profile detector-head design makes it suitable for commercial and institutional fire alarm applications.

Intelligent Fixed Temperature Detection

The ADT-HFS is specifically designed for 135°F fixed-temperature heat detection. Unlike combination heat detectors that incorporate rate-of-rise sensing, this model is identified as a fixed-temperature detector.

The detector continuously monitors the temperature of the surrounding air and communicates alarm information through the compatible intelligent fire alarm system.

Key Features

• Intelligent addressable heat detector
• 135°F fixed-temperature alarm point
• Designed for compatible ADT/Tyco systems
• Individual detector identification
• Low-profile detector-head construction
• Suitable for commercial fire alarm applications

Intelligent Detector Design

 Addressable operation allows the control panel to identify the detector associated with an alarm or system event.

This design makes the ADT-HFS useful for existing ADT/Tyco fire alarm installations requiring a compatible replacement fixed-temperature heat detector.
