Check Voltage at entry panel
Adjust the volume in the street panel
and in the handset.
1. Nothing works.
Check that there is voltage at the entry panel. Measure +/-
12V AC / DC across terminals 9,10. Check that power is
being supplied by either the power supply (check mains
supply and mains protection fuses) or the 12V DC of the
gate motor battery (check auxiliary supply fuses on the
motor consult motor manufacturer). Disconnect power to
the system and check for any short circuits or discontinuities
in the cabling between the power supply and the entry panel. 9. One handset does not receive the call from the entry
2. The illumination of the name-holder does not work.
Check the power input of the entry panel is approx.
12 V AC/DC between terminals 9 and 10. If the voltage is
correct, the module is defective.
3. Sound feedback (Larsen effect).
Adjust the volume in the entry panel.
4. None of the handsets' sound reaches the entry panel.
General installation problem. Check the volume adjustment,
the illumination of the light button and the connections
between terminals 4 and 2 of the entry panel. If the voltage
is correct, the entry panel may be defective.
5. One handset's sound does not reach the entry panel.
Handset individual problem. Check the connections
between handset terminals 4 and 2. If the voltage is correct,
the handset may be defective.
6. No sound from the entry panel reaches any handset.
General installation problem. Check the volume adjustment,
the illumination of the light button and the connections

the handset. If the voltage is correct, the handset may be
off-hook or defective.
10. The latch does not operate from any handset.
The lock must be powered. Check in the entry panel that
the voltage is approx. 12 V AC between terminals 9 and 10.
If not, refer to point No. 1. Press the electric lock button
and check in the entry panel that the voltage is approx. 12
V AC between the terminals 10 and 11. If not, the entry
panel may be defective. If the voltages are correct, the
problem is caused by the latch.
11. Gate release does not operate from one or more than
one handset.
Check continuity across terminals 2 and 3 on each
defective handset, with cabling to either or both these
terminals disconnected. If this test proves negative, the
