Hi,
I had a CP8L alarm previously installed in my house. The control panel became faulty so I decided to replace it with a more adaptable CPX control panel. I had read that the RKPs for the CP8L were compatible wth the CPX control panel. However, when I connect up one of the RKPs to the new CPX control panel it simply shows a back light and nothing else.
The RKPs were working fine with the CP8L and I have connected both of them directly to the CPX with a short cable (with nothing else connected and with all devices connected), to no avail.
Any help would be appreciated.
Thanks,
Darrn
