A radio, incorporating a selective calling capability, has an attention-getting device triggered by a dispatching center. A triggered device emits a sound alerting staff at a fire station, in an ambulance, on a vehicular radio or at a vehicular data terminal that an emergency call is pending. The act of ringing down a station may ring bells, activate a klaxon, turn off gas-fired cooking appliances, activate a volunteer alerting siren, turn on lights, and activate loudspeakers over which the call details are announced. Some systems use the voice path of a private line telephone circuit or a voice channel on a microwave radio instead of a two-way radio. Ringing down a vehicle may cause the radio or data terminal itself to beep continually until an acknowledge" button is pressed.

An Automatic ringdown circuit consists of two phones at different locations. When either phone goes off-hook, the one at the other end instantly rings.
