Telephone Interface Module
Art. 380N/UK Telephone Interface Module - Installation Instructions
CONNECTING MORE THAN ONE HANDSET
The
Art.380N/UK
is only capable of ringing a maximum of two
telephones with a REN value of 1 each (since the
Art.380N/UK
has a REN value of 2). Quite often the REN value of the telephone
can be found on a product label attached to the base of the
telephone or in any other technical documentation that may
accompany the telephone.
The
Art.380N/UK
would connect to the existing master socket
in the property. The primary telephone would be connected to
a new master socket from the
Art.380N/UK
, while the additional
telephone would be connected to a secondary socket, see
Fig.6
.

CONNECTING A REN BOOSTER
If more than 2 telephones are required they can be connected to
the
Art.380N/UK
via a REN booster (the REN booster, sometimes
referred to as a telephone extension booster, is a third party
product not supplied by Videx).
When using a REN booster it is important to note that the REN
booster itself will have a REN value (usually a REN value of 1) and
also requires it’s own power (typically 230Vac mains input).
IMPORTANT NOTE: When using a REN booster the Art.380N/UK
must be in PABX mode (refer to PABX setup and programming
on page 16). It will then be necessary to press ‘0’ on the
telephone to get an outside line.
Like in the example above the
Art.380N/UK
would connect to the
existing master socket in the property. The REN booster would
then be connected to a new master socket from the
Art.380N/
UK,
while additional telephones would be connected to the
secondary sockets connected from the REN booster, see
Fig.7
.
In the example,
Fig.7
, a secondary socket can still be connected
from the new master socket from the
Art.380N/UK
as the overall
REN value of the REN booster and Telephone 1 does not exceed
a REN value of 2. Additional secondary sockets can be connected
from the REN booster providing the overall REN value of the
telephones connected on the system (i.e. into the secondary
sockets) does not exceed a total REN value of 8, the maximum
REN value output of the REN booster.

IMPORTANT NOTE: The REN booster shown in Fig.7 above is to show how a REN booster can be connected from the Art.380N/UK
and it should be noted that the maximum REN value output of the REN booster may vary from manufacturer to manufacturer.
The total REN value output can usually be found in any accompanying technical documentation for the device.
CONNECTING TO A PABX TELEPHONE SYSTEM
There are two ways in which to connect the
Art.380N/UK
to a PABX telephone system:
• Connecting into a spare analogue trunk input (sometimes referred to as a trunk card);
• Connecting into an analogue extension.
Connecting into a Spare Analogue Trunk Input
Terminals T1 and T2 from the
Art.380N/UK
would connect directly into a spare analogue trunk input on the PABX telephone system.
In this instance the
Art.380N/UK
would be setup in PABX mode (refer to PABX setup and programming on page 16) and would
provide the line voltage, approximately 57-58Vdc, that would usually be provided by an ordinary incoming telephone line, refer to
Fig.8
on page 8.
The only other connections required from the
Art.380N/UK
would be the connections to the intercom door station, relay connections
to a lock (or volt free if connecting to an automated gate) and possibly the auxiliary outputs A1 and A2 if other devices are being
activated. Refer to the wiring diagrams on pages 19 - 22 for further examples.
