PURPOSE:To attain the check of a fault without visiting by a monitor person to the location of an object to be monitored at the generation of a fault by informing an operating sound to a remote location when the object to be monitored is faulty. CONSTITUTION:Microphones 6a-6n are fitted in the vicinity of corresponding objects 7a-7n to be monitored to configure an operating sound collecting means collecting the operating sound at failure or normal state of the objects 7a-7n and connected alternatively to a network control circuit 4 via a changeover device 8 configuring a switching means. A CPU10 checks the detection signal of all monitor sensors 2a-2n so as to discriminate the state of the objects 7a-7n to be supervised. When the object to be monitored is faulty, the CPU10 excites a relay M at first so as to connect a sound generating circuit 5 to the network controller 4, and transmits a voice signal such as ''the object XX to be monitored is failed'' to an informed destination and deenergizes the relay M and also connects the microphone corresponding to the object by operating the switching device 8 to the network controller 4 thereby transmitting the operating sound for a prescribed time. The operation above is performed sequentially with all objects to be monitored where any fault takes place. |
