Abstract
A personal alarm system is disclosed which incorporates a speakerphone so as to permit substantially handsfree operation and remote activation. The system includes a speakerphone which interfaces to a subscriber station. The subscriber station in turn interfaces over a communications link to a central monitoring station which is operative to receive and analyze messages transmitted to the central monitoring station by the subscriber station. Following transmission of a message from the subscriber station to the central monitoring station, the central monitoring station may transmit a control signal to the subscriber station which causes the subscriber station to activate the speakerphone 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 an automatic phone answering mode following the activation of a switch by a subscriber, a remote phone answering mode at the subscriber's location, and remote message mode for informing a caller to stand by while the subscriber comes to the phone. In a particular system, some or all operating modes may be employed.
