Abstract:
An escape system for alerting and aiding people in finding an exit door in a building in the event of an emergency situation of low visibility and/or fire within a building, said escape system comprising:at least one detector for detecting the occurrence of the emergency situation;detection signals broadcasted by said at least one detector after detecting the emergency situation;an alarm receiver unit located proximate the site of the emergency situation, having an audible alarm receiver for detecting said broadcasted detection signals;threshold detection circuitry associated with said alarm receiver unit, said circuitry analyzes said detection signal for false detection signals, and said circuitry digitizes said detection signal in radio frequency coded format;at least one alarm signal generated by said threshold detection circuitry, said alarm signal generated in radio frequency coded format by said threshold detection circuitry;a radio frequency transmission unit associated with said alarm receiver unit, said transmission unit transmits said at least one alarm signal;a door alert unit releasably positionable on the exit door;a radio frequency receiver unit associated with said door alert unit, said radio frequency receiver receives said alarm signal;decoding circuitry associated with said door alert unit, said decoding circuitry decodes said at least one alarm signal; andat least one light source positioned in said door alert unit, said at least one light source emits a high intensity light when said at least one alarm signal is decoded by said decoding circuitry;whereby people in the immediate vicinity of the emergency situation are guided to the exit door.
