Relay Operation
Radios are equipped with a relay that can be set for a relay switch closure when the RIB-600Analog receives a valid signal.
The relay can be used to
provide a “Priority”, “Override” or “Emergency” switch closure to the PA amplifier, enabling the
received signal to play over the PA system.
The Blue and Green wires on the
9-Conductor Interface Cable are used to connect
the relay switch.
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.
Radio Operation Timeline
The following timeline explains operation for RIB-600Analog radios. In this example the RIB-600Analog is programmed for:
Record and Play
Delay Message Playback of 10 seconds
Repeat Message Playback 3 times
Relay Operation Enabled
Pre-Announce Tone Enabled
Strobe Light Operation
The RIB-600Analog relay can be used to operate a strobe light in a number of configurations via the 9-Conductor Interface
Cable. The cable can provide:
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.
Example:
The strobe light and the relay function can be used to provide a visual indication that the Radio-To-Intercom Bridge
is being used. If located reasonably close to the installation site of the receiver, the strobe could be located in the
security office area.
