Abstract
A system for identifying the location of a fire extinguisher includes a fire detector with a wireless transmitter. When the detector goes into alarm, it not only emits a local audible alarm, it also transmits wirelessly a signal receivable by a fire extinguisher locating unit. This unit includes a receiver and circuitry for detecting the received alarm indicating signal. It also includes audible output circuitry, for example, speech synthesis circuitry, and optionally, an optical indicator. Upon detection at the unit of the alarm indicating signal, the speech synthesizing circuitry can be activated to indicate verbally the location of the extinguisher. Simultaneously, if desired, the illuminatable output device, such as a light bulb or light emitting diode, can be energized to provide a visual indication of extinguisher location.
