Abstract:

An escape system for aiding a person in finding an exit door in the event of an emergency situation of limited visibility. The escape system can includes at least one heat detector and at least one smoke detector, an audible alarm circuitry, a dynamic pulsating door base light, and an optional continuous door base light. Upon detection of a threshold amount of heat or smoke by detectors, an audible detection signal is received by a remotely located microphone, and a alarm signal is generated for transmission by radio frequency (RF) by a RF transmitter. The alarm signal is received by a RF receiver located in an exit door alert unit, having associated circuitry for activating dynamic pulsating LED lights within the door alert unit. The illuminating and flashing LED lights attract the attention of a person in distress who may be crawling along the floor in a smoke-filled room, therefor assisting people to locate and exit a smoke filled and burning enclosure.
