Title: Remote alarm device
Inventor: SATO TAKASHI
IPC: G08B27/00
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To transfer an abnormal signal generated by a simplified monitoring device fitted for crime prevention or disaster prevention to a pocket beeper and a portable telephone, to report abnormality to the person concerned at a distant place and to call that person. SOLUTION: Since four telephone numbers of the transmission destinations can be registered in a memory 4 in an input mode, pocket beepers or portable telephones 4 separately carried by four persons with them can be successively called. In manual transmission among transmission modes, any arbitrary destination can be selected out of the accepted four destinations. When there is no response of confirmation through a telephone even after the lapse of five minutes from call origination, an alarm showing no response is indicated and call re-origination is called. Even in automatic transmission, the absence of response is similarly judged, the destination is seleceted in the order of acceptance, and retransmission is automatically repeated.
