TROUBLE SHOOTING

Nothing works
a) Check the mains voltage b) Disconnect the
+, - terminals of the power supply and verify
that the voltage at the terminals is 15Vdc. If
there is no voltage detected at these terminals,
the power supply unit may be defective.
Otherwise, check if there is a short circuit in
the +, - connections between the devices of the
installation.
It is not possible to make a call from the
entrance panel. There is no voltage in the
entrance panel
If there is voltage in terminals 1,2 of the
entrance panel (12-15Vdc) see the next point.
Disconnect cables 1 and 2 of the monitor
and check the voltage in the terminals. If this
voltage is correct, check the cable between the
monitor and the entrance panel. Otherwise, if
the voltage is not correct, the monitor may be
defective.
It is not possible to make a call from the
entrance panel
Check the specifications about distances and
cross section cables shown in the first page of
this manual. If no fault is detected, the entrance
panel may be defective.
You cannot hear the entrance panel in the

The electric lock is not working
If the electrick lock has polarity, check that
the positive terminal is connected to terminal
5 and the negative terminal to terminal 6 of
the entrance panel. Verify that the terminal
resistance of the door opener is between 10
and 50 ohms.
Verify that the voltage is present in the electric
lock, if not, disconnect cables 5 and 6 from
the entrance panel and check the voltage in
terminals, if there is no voltage the entrance
panel may be defective. If not, check the cable
between the entrance panel and the electric
