Troubleshooting
SYSTEM CHECKS AND TESTING
The following table can be used to help diagnose any potential issues that may be occur during installation and the system checks
that can be carried out to help resolve them. In the event of problems occuring during the installation of the
Art.380N/UK
please
check through the troubleshooting table first before calling the Videx technical helpline on tel:
0191 224 3174
.
SYMPTOM
TEST
Telephone does not ring but if it is
picked up during a call there is speech
at the door.
Check to see if the
REN
value has been exceeded. Do the test again with only one telephone
connected. If it works then the
REN
value of the system has been exceeded and the number
of telephones on the system must be reduced. Alternatively introduce a
REN
booster that
is sufficient to accommodate the overall
REN
value of the number of telephones on the
system. Also refer to the chapter
Connections to Telephones & Other Devices
on page 7
for further guidance.
A master socket has not been fitted to the output of the
Art.380N/UK
. The telephone will
not ring if this is a secondary socket or a faulty master socket. To confirm if a master socket
is being used check to see if it has a large capacitor inside, a secondary socket will not have
one.
The correct output voltage is not coming or present from the
Art.380N/UK
. Use a digital
multi-meter to check for an AC voltage of approx. 30Vac on terminals
T1
and
T2
during the
ringing cycle.
Check to see if the ringing frequency jumpers are both present and are both set to 25Hz
position (default) or 50Hz position (in most cases these jumpers will not need to be adjusted,
however some telephones or telephone systems operate using a higher ringing frequency).
The speech lines do not open when
**7
is pressed on the telephone.
The
**
command on the
Art.380N/UK
has been disabled. To reinstate the
**
command
follow the 'hard-wired' reset procedure shown on page 13 in order to reset the
Art.380N/UK
back to factory defaults.
The telephone being used may not support
DTMF
dialling. Try a different telephone that
does support
DTMF
dial tones.
The door does not open when
0
,
8
or
9
is pressed on the telephone.
The lock is not wired correctly from the
Art.380N/UK
. Check the wiring between the
lock and the
C/NO
terminals on the
Art.380N/UK
for any breaks (check for continuity of
the lock wires). The
C/NO
terminals should short together when
0
,
8
or
9
(depending on
programming) is pressed on the telephone during a call.
The telephone being used may not support
DTMF
dialling. Try a different telephone that
does support
DTMF
dial tones.
The door opens when it should close
and closes when it should open.
The relay has been programmed to be either normally closed when it should be normally
open or normally open when it should be normally closed. Try reprogramming the relay to
the correct position required following the
Onboard Relay Reversal (C/NO or C/NC)
notes
on page 14.
The
Art.380N/UK
does not activate at
all when called.
Check the mains supply is connected and the mains input is between 230V-240Vac. Also
check the mains fuse inside the
Art.380N/UK
(always disconnect the mains supply first and
making it safe before removing the top cover).
Use a multi-meter to check to see if the
Art.380N/UK
is getting a signal across terminals
3
and
6
when a call is placed from the intercom door station (this will typically be approx 10
- 12Vac or dc depending on the intercom door station or interface connected). Without this
voltage the
Art.380N/UK
will not trigger).
Use a multi-meter to check to see if the
Art.380N/UK
is getting a voltage across terminals
3
and
2
when a call is placed from the intercom door station (this will typically be approx
8 - 12Vdc depending on the intercom door station or interface connected). Without this
voltage the
Art.380N/UK
will not ring the telephone connected).
There is no dial tone when the handset
is lifted.
Check there is a line dial tone before the
Art.380N/UK
by connecting the telephone directly
into the main incoming master socket in the property.
Check the line cord that came with the
Art.380N/UK
is connected to the main incoming
master socket in the property and that the cord itself is not faulty.
Check the line voltage across terminals
T1
and
T2
when the
Art.380N/UK
is connected into
the main incoming master socket in the property, this should be approx. 50Vdc.
