PURPOSE:To confirm the content of abnormality in a house by a telephone call even if an automatic answering set switch is left unchanged at a visit by providing a means changing over forcibly the automatic answering set switch to the position of automatic incoming call when an emergent input exists. CONSTITUTION:The automatic answering set switch 6 is changed over forcibly to the position of the absent home supevising mode by a forced changeover means 16 when a detected output of an emergent input detecting means 12 exists. Thus if an external telephone call is incoming in the timing when an automatic dial means 13 openes a telephone line 7, an automatic incoming means 15 is operated and the telephone line 7 is brought into a talking state. Since a voice message transmitting means 14 receives an emergency input and the telephone line 7 is in the talking state, the voice message for emergency information is transmitted via the telephone line 7. Even if the automatic answering set switch 6 is not depressed beforehand, the content of emergency is known by a telephone call. |
