Abstract

A radio receiver is described for a system involving the prioritised transmission of warning signals via radio transmitters. The radio receiver in the alarm centre compares a control signal received via the transmission path with the original control signal transmitted via a delay path, enabling the transmission of the warning signal if the control signals correspond. <IMAGE>
