Vista SAMS20P checkout

Just moved into a new house (to me) and there is an alarm system installed and it appears to be in good condition.
What is strange is that the motion sensors clearly have power but the two keypads do not.
Tonight I am going to check the voltages on the various terminals and see what I find.
There is also what appears to be a wireless remote.
Is there a normal use case where the wired keypads would not be on?
It could be they are not fully connected...
