Notifier FST-851A Intelligent Heat Detector

Notifier FST-851A Series intelligent plug-in thermal detectors with integral communication have features that surpass conventional detectors. Also, point ID capability allows each detector’s address to be set with rotary, decimal address switches, providing exact detector locations. Besides, FST-851(A) Series thermal detectors use an innovative thermistor sensing circuit to produce 135°F/57°C fixed-temperature (FST-851/A) and rate-of-rise thermal detection (FST-851R/A) in a low-profile package. FST-851H(A) provides fixed high-temperature detection at 190°F/88°C. These thermal detectors provide effective, intelligent property protection in a variety of applications. Furthermore, Notifier FST-851A Series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).

In general, FlashScan® (U.S. Patent 5,539,389) is a communication protocol developed by Notifier Engineering that greatly enhances the speed of communication between analog intelligent devices as well as certain NOTIFIER systems. Intelligent devices communicate in a grouped fashion. Additionally, If one of the devices within the group has new information, the panel’s CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of earlier designs.
