ABSTRACT:
An alarm device for a fire extinguisher to detect when the fire extinguisher is removed from its storage post includes a flexible cable which is slidably insertable within a guide passage between the permanent magnet and a reed switch. One end of the cable is inserted into an alarm housing which contains the reed switch and magnet while the other end of the cable is fixedly secured to a fire extinguisher of the stationary support post. In the first instance, the alarm housing is secured to the stationary storage post while in the second case the alarm unit 16 is secured by a harness to the fire extinguisher itself. In either case, movement of the fire extinguisher causes the flexible cable to withdraw from the alarm housing and closed the reed switch to complete a circuit which produces an audible alarm signal.
