TROUBLESHOOTING HINTS

Nothing operates.
Check the output transformer voltage between SEC terminals: it should have 12 to 17Va.c. If
not, disconnect the transformer from the installation and measure again. If it's correct now,
it means there is a short circuit in the installation: disconnect the transformer from mains
and check the installation.
Inappropriate audio level.
Adjust the level volumes as shown on page 24. In case of feedback, reduce the audio levels
until feedback fade out.
Door open function no operates.
Disconnect the lock release from the main module and short-circuit terminals ' ' and 'P': at
that moment the output voltage between terminals 'CV' and '~2' of the main module
should be 12Va.c. If it's so check the lock release, its wiring and the wiring of the terminal
'P' from the main module to the telephones. If these tests don't solve the problem, replace
the main module.
No telephones receive the call or acknowledgement call signal is not reproduced.
Check that the call wires are connected to a valid terminals. In case of door panels with push
buttons modules, check the 'CP' terminal connection to the main module. Both procedures
are described on page 27.
The maximum number of telephones placed
in the same apartment is three.
For each telephone placed in parallel
the section corresponding to the call wire
must be doubled.
