Intelligent plug-in thermal detectors with integral communication

Thương hiệu: Notifier
Loại: Khác
Mã SP: FST-851(A) Series

Notifier FST-851(A) Series intelligent plug-in thermal detectors with integralcommunication has features that surpass conven- tional detectors. Point IDcapability allows each detector’s address to be set with rotary, decimaladdress switches, pro- viding exact detector locations. FST-851(A) Series thermal detectors use aninnovative thermistor sensing circuit to pro- duce 135°F/57°C fixed-temperature (FST-851/A) and rate-of-risethermal detection (FST-851R/A) in a low-profile package.FST-851H(A) provides fixed high-temperature detection at 190°F/88°C. These thermaldetectors provide effective, intelli- gent property protection in a variety ofapplications. FST- 851(A) Series detectors are compatible with Notifier Onyxand CLIP series Fire Alarm Control Panels (FACPs).

FlashScan® (U.S. Patent 5,539,389)is a communication pro- tocol developed by Notifier Engineering that greatlyenhances the speed of communication between analog intelligent devices andcertain NOTIFIER systems. Intelligent devices communicate in a grouped fashion.If one of the devices within the group has new information, the panel’s CPUstops the group poll and concentrates on single points. The net effect isresponse speed greater than five times that of earlier designs.
