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 verbal and non-verbal indicators of the presence of an alarm condition for use in evacuating the region. A second port disables the non-verbal outputs. 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 non-verbal outputs can be disabled, while verbal directions can continue to be emitted.

Directional sound system with messaging

A sensor of incident ambient photons is combined, in a detector with one or more sensors responsive to other types of ambient parameters such as gas, humidity, temperature or the like. Outputs from the sensors are processed to establish the existence of one of a hazardous condition, a non-hazardous condition and a false alarm.
