Patent ID: 7636049

Claim:
An emergency notification and directional signaling escape indicator apparatus usable with an emergency event detector generating a first signal output upon detecting an emergency event, the apparatus usable with at least one escape exit and comprising: a detector capable of generating a signal upon sensing an output signal from the emergency event detector; a transmitter responsive to the detector signal from the detector for generating a first signal frequency; at least one housing adapted to be mounted on a surface in proximity to an escape exit; an alarm providing at least one of an audible alarm and a visual alarm; a receiver generating an output signal in response to the first signal frequency activating the alarm upon receiving the first signal frequency the alarm and the receiver carried in the housing; and a temperature sensor, carried in the housing, for sensing the ambient temperature adjacent to the housing, the temperature sensor generating an output signal upon detecting a temperature above a predetermined threshold temperature, the output signal activating at least one of a second notification and directional signaling event.
