Thermal (Heat) Detectors

FST-851, FST-851R, FST-851H

The FST-851 is a Fixed Temperature Thermal Detector for use with ONYX Series panels.

The FST-851R is a Rate-of-Rise Thermal Detector for use with ONYX Series panels.

The FST-851H is a High Temperature Thermal Detector for use with ONYX Series panels.

Intelligent (addressable) detectors with point ID capability that enable each detector address to be set with rotary address switches to provide exact detector locations. Our thermal detectors use an innovative thermistor sensing circuit to produce 135°F fixed, rate-of-rise and 190°F high-temperature detection for cost-effective, intelligent property protection.
