Specification of FST-851 ROR / Fixed Heat Detector
Notifier FST-851(A) Series intelligent plug-in thermal detectors with integral communication has features that surpass conven- tional detectors. Point ID capability allows each detector’s address to be set with rotary, decimal address switches, pro- viding exact detector locations. FST-851(A) Series thermal detectors use an innovative thermistor sensing circuit to pro- duce 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, intelli- gent property protection in a variety of applications. FST- 851(A) Series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).
FlashScan® (U.S. Patent 5,539,389) is a communication pro- tocol developed by Notifier Engineering that greatly enhances the speed of communication between analog intelligent devices and certain NOTIFIER systems. Intelligent devices communicate in a grouped fashion. 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.
