ABSTRACT:
An exit path indicating device incorporates at least a first port for receiving an alarm indicating signal. In normal operation upon receipt of the alarm indicating signal, the device outputs a visual or an audible, or both, indicator of the presence of an exit or egress path for use in evacuating the region. A second port disables the operation of the device. The second port can be coupled to a local sensor which provides an indication of a hazardous or alarm condition adjacent to or on the exit or egress path. If the sensor is indicating the presence of a hazardous or alarm condition, the indicating device can be disabled.
