Hi Paul,

When the panel is replaced, the new panel needs to be programmed to receive the wireless sensors.

Do you have the programming manual available?

What all programming has been carried out?

Customer: replied 4 months ago.
I have all of the documentation, but I used the Honeywell Compass software to download all of the programming data, including the addresses of the wireless devices.

Ok, so the programming of the new control panel may be incorrect.

Can you try reprogramming just one of the old sensor zones and check if it works?

I went through several programming iterations. I even considered another house code, but this house is 1/2 mile from another dwelling. Sensor still just activate the Interference LED when a covered door or window is opened.

Hmm ok, let me check if the other experts have any idea on this...

I answered this myself. 1. Pull batteries from all of the devices. 2. Kill main and back-up power to the panel. 3. Replace batteries in the devices. and 4. Power the panel back up.
