System Sensor-4WITAR-B i3 Photo Detector, Plug-In, 4-Wire, 12/24 Vdc, Isolated 135 deg F Thermal, Temporal 85 dBA Sounder, Form-C Relay.4WITAR-B are 4-wire photoelectric smoke detectors. All models incorporate a state-of-the-art optical sensing chamber and an advanced microprocessor. The microprocessor allows the detector to automatically adjust its sensitivity back to the factory setting when it becomes more sensitive due to contaminants settling in its chamber. In order for this feature to work properly, the chamber must never be opened while power is applied to the smoke detector. This includes cleaning, maintenance or screen replacement. All models also feature a restorable, built-in, fixed temperature (135°F) thermal detector and are also capable of sensing a freeze condition if the temperature is below 41°F. 4WITAR-B photoelectronic smoke sensor is isolated from the fixedtemperature heat sensor, providing a self-resetting, local audible smoke alarm that does not alarm at the panel. Only the fixed-temperature heat sensor will cause the 4WITAR-B to initiate an alarm at the panel and the relay to change its state.
