System Sensor 5251B Fixed Temperature Thermal Detector FSP — RA400Z(A): Remote LED annunciatorSystem Sensor 5251B and 5251RB detectors use an innovative thermistor sensing circuit to produce 135F fixed and rate of rise thermal detection in low profile packages. Besides, the 5251H model provides fixed high temperature detection at 190F. In addition, these thermal detectors provide cost effective, intelligent property protection in a variety of applications. Furthermore, the 200 Series smoke detectors are intelligent (addressable) detectors with
