How to Program a Push Button or Sensor to the LRA-DCRXS

Instructions for programming an LRA transmitter/sensor to the LRA-DCRXS Receiver, which has two zones. Each zone can be assigned a different melody for identification.

Published November 19, 2021

Plug the LRA-DCRXS receiver into a standard wall outlet.
Ensure the transmitter/sensor has new batteries in it.
Hold down the "Learn" button on the LRA-DCRXS for approximately 3 seconds.
After 3 seconds, a red LED should start flashing inside the strobe lens. If the red LED is solid, consult the FAQ document to erase programming.
Once the red LED is flashing, press the "Melody" button until you hear the desired sound or melody.
Push the transmitter you want to program to the receiver.
If programming a second zone, scroll through melodies again and press/trigger the second transmitter when you find the desired melody.
