The "U" series handsets are not compatable with the newer keyapds and controllers. FACT. i've had this fact verified by diarme/logistys technical director Phill Hand.
I Know this from expereince if you load them into the system, when the call station rings the handset all you will hear is white noise and none of the functions will work all though it does ring.
So in effect all you are left with is a glorified door bell.
Only way to overcome this is two change the handsets.
