Telephone Interface Module
Art. 380N/UK Telephone Interface Module - Installation Instructions
BALANCE CONTROL POT
The balance control POT, see
Fig.3
, allows the speech volume of the
Art.380N/UK
to
be adjusted in conjunction with the mic and speaker volumes of the door station (or
interface:
Art.2280
or
Art.2380
) that the
Art.380N/UK
is connected to. If the speech
towards the telephone is poor adjusting the balance control POT will improve it.
By default this is set to approximately half way and can be adjusted to increase (turning
the POT clockwise) or decrease (turning the POT anti-clockwise) the overall speech
volume of the
Art.380N/UK
.
When making any adjustments to the speech volume of the system it is recommended
that the mic and speaker POTs of the door station are adjusted first. Next adjustments
can be made using the
27
command (refer to notes on page 17). Finally the balance
control POT can be used to ‘fine tune’ the speech volume to an acceptable level since
the overall speech volume of the system that the
Art.380N/UK
is connected to will vary
from system to system.

TERMINAL CONNECTIONS
Terminal
Description
230Vac
Live terminal for mains input.
230-240Vac @ 50/60Hz operating frequency
0
Neutral terminal for mains input.
+12 (x2)
+12Vdc power outputs, 100mA max. (can be used to trigger a DC relay in conjunction with auxiliary A1 or A2).
–
0V ground.
SK
Clock signal for use with Videx serial bus devices. Normally sits at 12Vdc and will alternate during data transfer.
Also used for hard wired reset when linked to -(0V ground) terminal.
SI
Data signal for use with Videx serial bus devices. Normally sits at 12Vdc and will alternate during data transfer.
L1 / L2
Telephone Line inputs. Can be used as an alternative connection to the line/tel RJ11 socket and usually connected
to the main incoming BT line (from original BT master socket in the property).
T1 / T2
Telephone Line outputs. Linked internally to the L1/L2 line inputs when Art.380N/UK in standby. Both connections
T1/T2 to new master socket in the property (connects to terminals 2 and 5 within new master socket).
2
Receive speech (Rx) from the door panel. Sits between 8-12Vdc (approx.) in standby. Will drop down to 1Vdc
(approx.) during conversation from door panel (live speech).
1
Transmit speech (Tx) to the door panel. Sits between 8-12Vdc (approx.) in standby. Will drop down to 4Vdc
(approx.) during conversation to door panel (live speech).
3
0V speech ground input (also used as reference point for voltage checks).
6
Call line trigger input from door panel to activate a call to the telephone. Will sit at 0V in standby and will jump up
to 8-12Vac or dc when the call button is pressed on the door panel.
NO (NC)
Normally open relay output (default). Relay polarity can be adjusted to NC via programming (refer to page 14).
C
Common relay output.
A2
Auxiliary output 2, open collector output (200mA max.) and becomes 0V when activated. Can be either momentary
or latching depending on programming (refer to page 14).
A1
Auxiliary output 1, open collector output (200mA max.) and becomes 0V when activated. Can be either momentary
or latching depending on programming (refer to page 14).
