Abstract
An emergency signalling unit which is designed to be carried on the person of a fireman or other worker to alert control personnel should the worker become endangered, and an alarm system which incorporates a plurality of such signalling units, each one worn by a different fireman, for providing an alarm at a central station and an indication of which fireman is in trouble, as well as a means of locating him. The emergency signalling unit includes a radio transmitter, a high intensity strobe lamp, and an audio frequency generator. The alarm system includes a plurality of the above-mentioned radio transmitters, each transmitting on a different carrier frequency, and a receiver at a central control station exterior to the burning building, which is equipped to identify the respective carrier signals and to provide a visual indication of which fireman is in trouble as well as an audible signal to alert control personnel to the existence of an alarm condition.
