Paging Controlled Relay

The RDL-TX-PCR1 is the ideal choice in many applications where switching needs to be controlled from a constant-voltage amplified audio source. The module will trigger on any program material, with paging sources being the most common. It is ideal to provide local speaker muting during an area page. During an announcement, speaker systems can be switched on the annoucement system and after it, back to the nomale system. If additional speaker lines need to be switched, the SLAVE terminal may be used to control additional RDL-TX-PCR1 modules or RDL-ST-LCR1H High Power Logic Controlled Relays.

The module is triggered when the audio exceeds the threshold and it remains triggered for a defined time duration after the audio falls below the threshold. This DELAY is adjustable from 3 to 25 seconds using a front-panel trimmer. Use the RDL-TX-PCR1 relay contacts to switch speaker lines or to control the logic inputs of other equipment with control inputs that may not be pulled up to 24 V. The SLAVE terminal may be used as either an input or output control terminal.
