INSTRUCTIONS
NC/321 HANDS-FREE
AUDIO MODULE
Hands-free audio module for use in
series-300 audio entry installations
and, teamed with monitor module
NVM/300, in series-300 video entry
installations.
Is inserted in a standardised rectan-
gular single embedding box or com-
bined with the monitor module in a
standardised double embedding
box.
The unit comes with a chassis and
adapters for the use of a number of
commercially available front plate
models.
It features the following controls and
warnings (fig. 1):
•
Auxiliary services
•
Door-lock release
Audio
LED Red LED indicating audio con-
nection is active
Hands-free operation
Press the audio button for less than
0.5 s to initiate communication with
the entry panel (the LED lights).
5
To cut off communication, press the
audio button again for less than 0.5 s
(the LED flashes).
Afterwards, communication can be
restarted within 30 s, after which the
system switches off (the LED goes off).
Talk-listen operation
Keep the audio button pressed to ini-
tiate communication with the entry
panel and start talking (the LED
lights). Release the button to listen.
To cut off communication, press the
audio button for less than 0.5 s (the
LED flashes).
Afterwards, communication can be
restarted within 30 s, after which the
system switches off (the LED goes
off).
Calibrating the audio levels
- Activate the receivers and select
the talk-listen operating mode.
- Adjust the volumes on the entry
6
panel in the talk-listen mode.
- Go to the hands-free mode and
check the regularity of switching from
one channel to another.
- If there is difficulty in getting the
line in one of the two directions,
increase the volume slightly in the
direction where you have difficulty
and reduce it in the other direction.
In combined systems (receivers and
hands-free) we recommend you first
adjust the communication levels for
the hands-free system.
If necessary, adjust the volumes on
the entry panel to achieve a better
compromise.

Normally supplied ready inserted.
Remove the jumper SW1 (fig. 2) in
the event the volume of the call note
is to be attenuated.
Maximum number of receivers acti-
vated by same call:
- 3 with normal call (jumper SW1
inserted);
- 1 with normal call and 7 with attenua-
ted call (jumper SW1 not inserted).
Function of connector CN1
Connector to be used to connect the
audio module to monitor module
NVM/300 using the relevant cable
(fig. 2).
Function of connector CN3
Connector for remote control for acti-
vating audio and door lock release
command (fig. 2).
