continued from previous page.
Check the new master socket fitted across terminals
T1
and
T2
of the
Art.380N/UK
has the
wires connected into terminals
2
and
5
of the master socket.
Check the telephone being used is working correctly.
No speech from the door station to the
telephone (line 2).
Check terminal
2
from the intercom door station (or interface:
Art.2280
or
Art.2380
) to
ensure there is no break in the wire.
Check the voltage across terminal
2
and
GND
at the door station (or interface:
Art.2280
or
Art.2380
) and across terminals
2
and
3
at the
Art.380N/UK
. When there are no calls on the
system (in standby) a voltage of approx. 8 -12Vdc should be present.
If possible, test the speech from the door station using a Videx audiophone (model
Art.3021
should be sufficient).
No speech from the telephone to the
door station (line 1).
Check terminal
1
from the intercom door station (or interface:
Art.2280
or
Art.2380
) to
ensure there is no break in the wire.
Check the voltage across terminal
1
and
GND
at the door station (or interface:
Art.2280
or
Art.2380
) and across terminals
1
and
3
at the
Art.380N/UK
. When there are no calls on the
system (in standby) a voltage of approx. 8 -12Vdc should be present.
If possible, test the speech from the door station using a Videx audiophone (model
Art.3021
should be sufficient).
The speech is too loud and feedback
occurs or the speech is too low.
Try adjusting the volume at the door station using the volume control POTS (mic, speaker
and depending on the panel balance). Also refer to
speech adjustment
notes on page 17.
Try adjusting the external speech volume using the
27
programming command. Also refer
to
speech adjustment
notes on page 17.
Try adjusting the
Art.380N/UK
balance POT, also see balance POT notes on page 5.
IMPORTANT NOTE: The suggestions covered in this troubleshooting section primarily covers the system checks to try for the
Art.380N/UK telephone interface module. Since the telephone interface will be connected to an intercom panel it is always
recommended that you also refer to the troubleshooting section on any accompanying technical documents for the intercom
panel being installed, as there may be solutions to the problems that you’ve encountered covered in those documents that
may not necessarily be covered in the troubleshooting table.
