Environmental condition detector with remote fire extinguisher locator system
First Claim
1. An apparatus to identify the location of a displaced fire extinguisher comprising:
- a detector for detecting the presence of fire in a region, wherein the detector includes electronic circuitry including an audible alarm indicating output device and a wireless transmitter wherein the device and the transmitter are activated to emit respectively an audible alarm and a wireless signal for the duration of the condition detected by the detector; and
a displaced wireless signal receiver independently positionable relative to the detector capable of receiving and decoding the wireless signal from the detector wherein the wireless receiver includes circuitry to activate one of an audible alarm or a recorded verbal location identifier at the location of the fire extinguisher to facilitate location thereof the receiver is carried in a portable housing which also carries an emergency light.

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.
