Relay Operation
Radios are equipped with a relay that can be set for relay switch closure when the Loudmouth
®
receives a valid signal. The
relay can be used to enable an optional strobe light for visual indication that a Loudmouth
®
speaker message is in process.
With the Relay Option enabled:
If Record and Play is disabled
The relay switch will close as soon as a valid signal is received, and will remain
closed as long as the signal is present.
If Record and Play is enabled
The relay switch will close as soon as a valid signal is received and will remain
closed until the recorded message has finished playing.
If Delay Message Playback is programmed
The relay switch will close as soon as a valid signal is received, and will remain
closed for the delay time and until the recorded message has finished playing.
If Replay Message Playback is programmed
The relay switch will close as soon as a valid signal is received, will remain
closed for any Delay Message Playback time and until the recorded message
has
been repeated in it’s entirety.

A normally open relay switch that closes on a received signal. The relay switch can handle up to 3A when used to
connect power to a strobe light.
A normally closed relay switch that opens on a received signal.
A +10.5VDC supply that can be used to power an LED strobe light rated at 400mA or less.
A ground connection that can be used to provide a switch closure to ground.
