2WT-B

The System Sensor 2WT-B is a i3-Series conventional, two-wire, photoelectric smoke detector with fixed 135° thermal sensor. Add the hardwired 2WT-B smoke detector to most existing alarm system control panels.

The System Sensor 2WT-B smoke detector is not the typical conventional detector. In fact, the 2WT-B is a System Sensor i3 series intelligent detector that includes many of the same features found in analog smoke detectors. Drift compensation and smooting algorithms, standard on the 2WT-B, ensures the smoke detector does not become over sensitive as it becomes dirty or dusty. Measuring the specific sensitivity of the 2WT-B smoke detector is made easy with the unique sensitivity reader. Simply position the reader near the word “PAINT” and it displays sensitivity in terms of percent per foot obscuration. A text message then indicates whether or not cleaning is recommended. Using an infrared signal, the reader eliminates the need for a voltmeter, magnets, counting LEDs and connecting to the detector. The 2W-B features both a local and remote maintenance signal that indicates when the smoke detector needs cleaning. Activated by the i3 loop test and maintenance module, or by any i3 ready control panel, the i3 remote maintenance signal means fewer nuisance calls and reduced maintenance costs.
