Short answer: This page explains trouble programming the lra-dcrxs receiver in practical terms, with links to the products, setup guides, and troubleshooting steps that usually matter next.

The LRA-DCRXS has two zones. Oftentimes, programming problems occur when a zone is already occupied and you are trying to program a transmitter to a zone that is already occupied. As mentioned above, the status of the red LED (once the unit is entered into program mode) is a signal to the zone programming.

If the red LED is blinking rapidly, then zone one is open. If the red LED is blinking slowly, that means zone one is occupied is zone two is open. If the red LED is not blinking (solid), that means both zones are already programmed to a transmitter.

If the transmitter/sensor will not pair to the receiver, the easiest thing to do is to delete the memory and reprogram the transmitter to the receiver. To remove the memory, consult the FAQ document, Deleting Memory from the LRA-DCRX & LRA-DCRXS Receiver. Once you have deleted the memory, re-program the transmitter/sensor to the receiver.

Another issue could be the compatibility between older models of the LRA products to newer models. For this, please consult the FAQ document, LRA Series Compatibility Notice.
