Ionization Smoke Detector

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.

Model 1251B ionization detector incorporates a unique single source, dual chamber design to respond quickly and dependably to a broad range of fires.
