Personal alarm system providing handsfree operation.

摘要

A personal alarm system is disclosed which incorporates a speakerphone so as to permit substantially handsfree operation and remote activation. The system includes a speaker phone (20) which interfaces to a subscriber station (10). The subscriber station (10) in turn interfaces over a communications link (12) to a central monitoring station (14) which is operative to receive and analyze messages transmitted to the central monitoring station (14) by the subscriber station (10). Following transmission of a message from the subscriber station (10) to the central monitoring station (14), the central monitoring station may transmit a control signal to the subscriber station which causes the subscriber station to activate the speakerphone (20) to permit verbal communication with a subscriber who may be immobilized and/or physically unable to initiate a telephone call or answer a telephone. The system further includes means for automatic phone answering following the activation of a switch by a subscriber and means providing for remote phone answering at the subscriber's location.
