Because noise in the factory does not hear the phone ringing sound, buzzer of treble and the like is noisy at night. Before

Since the thing of the previous purchase was wireless, it was okay to move away from the phone body, but construction was troublesome because the thing purchased this time was wired.

Incoming calls are not known in environments where noises, such as machine tools, compressors, welding operations, grinders and the like cans factories (metal product processing) are intense, so that incoming calls are detected so as to drive the patrites and the alarm.

It does not respond to loud sounds other than telephone calls and can reliably detect only ringing tones of the phone. The set of sensitivity adjustment etc was very easy and work was easy. Since it is indirectly detecting the ringing tone of the telephone, it does not affect the telephone line, so it is good. that's all.
