the voltage between
Vac. Check whether there are any short circuits and fix
them. Disconnect the power supply for 1 minute and then
connect it up again.
If it still doesn't work, disconnect all the power supply V
and terminals, and check that the voltage between
and V is 12 Vac, if this is not the case then there may
be something wrong with the power supply.

you press the door-openers, is 12 Vac. If you cannot find
the fault, the lock may be broken.
The door-opener doesn't work unless someone
presses a push button
Check that at least one entrance panel has been defined
as the main one. If you cannot find the fault, there may
be something wrong with the audio unit.
