Replaced CO Sensor, Now “Transmitter Missing”

[kevkmartin]

I have an ELK M1 system, using Honeywell 5800 series wireless trans / receivers.

Recently, I had an end-of-life CO sensor. I replaced it with a new sensor, and used ELK RP to replace the ID for the zone with the new units ID.

Now, every arm / disarm, the ELK states “Transmitter Missing”.

What did I miss when I swapped out the CO sensor?

You need to delete the old transmitter id so that it is no longer enrolled.

Where / how do I do that? I replaced the old sensor ID with the new one on the wireless tab for the zone.

The delete process is explained on page 11 of the M1XRF2H manual.  Basically, you go through the enrollment process and manually enter the transmitter id, along with "0"  (zero) for the loop number.
