Intelligent Thermal (Heat) Detectors

FST-851 Series Intelligent Plug-in Thermal Detectors with integral communication has features that surpass conventional detectors. Point ID capability allows each detector’s address to be set with rotary, decimal address switches, providing exact detector locations. FST-851 Series thermal detectors use an innovative thermistor sensing circuit to produce 135F/57C fixed-temperature (FST-851/A) and rate-of-rise thermal detection (FST-851R/A) in a low-profile package. These thermal detectors provide effective, intelligent property protection in a variety of applications. FST-851 Series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).

The FST Series plug-in intelligent thermal detectors use a separate base to simplify installation, service, and maintenance. Installation instructions are shipped with each detector. A special tool allows maintenance personnel to plug in and remove detectors without using a ladder.
