Abstract

PURPOSE: To exactly notify the approach of an emergency vehicle by providing a radio receiver for receiving radio wave generated in advancing direction from the emergency vehicle and warning means operated upon receipt of the radio wave at the receiver.
CONSTITUTION: When an emergency vehicle runs in emergency, a receiver 2 having an antenna 1 receives the radio wave generated in advancing direction from the emergency vehicle and produces its output, which is applied to a control circuit 3. The output from the control circuit 3 operates an indicator 4 as warning means and a unit 5 for disconnecting a sound source such as an automotive radio receiver or the like. the receiver 2 has a sensitivity for operating the warning means when the emergency vehicle approaches, for example, 500m at distance.
