The System Sensor 1251B ionization detector incorporates a unique single-source, dual-chamber design to respond quickly as well as dependably to a broad range of fires. Also, the System Sensor 1251B Series intelligent plug-in smoke detectors with integral communication provide point locations for alarm communication and selective maintenance. Besides, the System Sensor 200 Series intelligent plug-in smoke detectors with integral communication provide point location for alarm communication and selective maintenance.
In general, the System Sensor 200 Series smoke detectors are intelligent (addressable) detectors with point ID capability that enable each detector address to be set with decade address switches to provide exact detector locations. Furthermore, the sensitivity of 200 Series detectors can be programmed using the control panel software to suit the environment. In addition, detector sensitivity is continually monitor and report to the panel.
