I tried transmitting the serial number in Honeywell Lynx L3000 zone programming and it is giving me a totally different serial number. What do I do?
This may be caused by transmitting the signal too close to the receiver, the device is defective or the device has been mislabelled with the wrong serial number.
The best way to get around this is to manually enter the serial number. After you finish the zone programming; be sure to test.
