System Sensor 200 Series intelligent plug-in smoke detectors with integral communication provide features that surpass conventional detectors. Detector sensitivity can be programmed in the control
panel software. Sensitivity is continuously monitored and reported to the panel. Point ID capability allows each detectors address to be set with decade address switches, providing exact detector
locations for selective maintenance when chamber contamination reaches an unacceptable level.
Models 5251B and 5251RB use an innovative thermistor sensing circuit to produce 135
