Abstract

The system, automatically relays the received alarm call to the relevant emergency service etc. It allows a message to be sent along the subscriber telephone line, with the vocal signals received from the latter being recorded and the entire process repeated a given number of times. A radio signal is transmitted for paging required personnel modulated while the message is sent along the line in dependence on the coded paging signals and modulated by the vocal signals during recording of the received message. Pref. a clock signal is recorded alongside the received message.
