It is possible to use the screwdriver obtained from
the spacer to adjust the microphone and speaker
volume (fig. 4).
WARNING. Connecting cables must be fed
through one of the knockout cable entry points,
located at the bottom of the embedding box (A in
fig. 14).
Using the Allenkey s 2.5 supplied, unscrew the lock
screw and remove the front plate from the chassis
(fig. 15).
In order to fit additional buttons, follow the instruc-
tions supplied with each.
Remove the two plugs protecting the threaded holes
in the embedding box and secure the chassis using
the two screws supplied (fig. 16).
Perform the wiring. The name card can be removed
and filled in with the relevant information by removing
the card clip followed by the actual card itself (fig.
17).
NOTE. Personalized name cards can be used up
to a maximum of 2 mm thick.
In order to fit the front plate, first insert the upper part
in the top moulding and then, using a Allenkey s 2.5,
tighten the lock screw (fig. 18).

The video handset is fitted with a differentiated call
input (terminal
) (i.e.: for calls from landing and
external entry panel) a continuous tone call (approxi-
mately 2 s).
Function of connector CN1 (NC/321)
Connector to be used to connect the audio module
to monitor module NVM/301 using the relevant cable
(fig. 19).
Function of connector CN3 (NC/321)
Connector for remote control for activating audio
and door lock release command (fig. 19).
Function of jumper SW1 (NC/321)
(Call attenuated)
Normally supplied ready inserted. Remove the jum-
per SW1 (fig. 19) in the event the volume of the call
note is to be attenuated.
Maximum number of receivers activated by same
call:
- 3 with normal call (jumper SW1 inserted);
- 1 with normal call and 7 with attenuated call (jumper
SW1 not inserted).
Function of jumper SW1 (NVM/301)
(Resistive load termination)
The unit features a jumper
SW1
(fig. 19) for the
impedance terminating the signal line.
Remove the jumper if the line continues towards
other receivers.
Function of jumper SW2 (NVM/301)
(Selects power source)
The video handset has a jumper
SW2
(fig. 19) for
selecting the type of power supply (from BUS or a
separate power supply unit).
For power supply from X1 BUS
(max. 1 video hand-
set active only)
, position jumper
SW2
on
BUS
(default setting).
For separate power supply, position jumper
SW2
on
LOCAL
(as additional receiver for a simultaneous call
or use in X2, 300 installations).
Function of connector CN1 (NVM/301)
(Connection to the audio module NC/321)
Connect monitor module to audio module with the
relevant cable supplied (fig. 19).
Afterwards, communication can be restarted within
10 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 panel in the talk-
listen mode.
- Go to the hands-free mode and check the regu-
larity 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 lev-
els for the hands-free system.
If necessary, adjust the volumes on the entry panel
to achieve a better compromise.
VIDEO ENTRY PANEL HEVC/301
Video entry control panel with one button, equipped
with CCD colour camera and white light LED to illu-
minate the subject.
Teamed with button plates HEP/306-HEP/312D,
installations with up to 64 users can be set up.
For connections to user extensions the entry panel
uses BPT
X1 TECHNOLOGY
bus connection, ena-
bling all signals involved in installation to be sent
along a telephone-type single twisted pair line.
An additional three video-entry or audio-only entry
panels can be added to the first in series without the
need for other equipment (selectors, distributors).
The entry panel comes ready to house the KHSO
luminous system busy warning kit and 1 KHPS (or 1
KHPD) call kit.
The entry panel comes complete with:
- CCD camera with ±11° manual angle adjustment
both horizontally and vertically (fig. 4), with fixed-
focus lens (see fig. 5 for dimensions of the target
area);
- phonic unit;
- infrared LED for lighting the target area;
- three potentiometers for the following functions
(fig. 4 and 6):
volume control at entry panel;
volume control at receiver;
P1
timed (in the range 1 to 15 s) solenoid door-lock
release.
The entry panel comes with system busy and door-
lock release buzzer.
The wires supplied make it simple to connect the
entry panel’s various component units.
ASSEMBLY INSTRUCTIONS
NVM/301+NC/321 HANDS-FREE COLOUR
VIDEO HANDSET
The monitor module can be installed teamed with
twin-channel module NC/321 in an embedding box
(fig. 7), or on its own teamed with the twin-channel
module (fig. 2).
In the latter case, the distance between the modules
will depend on the length (24 cm) of the cable sup-
plied.
Recess the embedding box flush with the wall at a
suitable height for the user.
ATTENTION
- If you need to remove the installed adaptors,
proceed as shown in figure 8.
- If it is necessary to extract the frame modu-
les, use the locking tabs and push from the
rear (figure 9).
Examples of assembly of monitor
NVM/301+NC/321 in a standard six-module
embedding box with a number of commercially
available front plates (fig. 10-11).
Examples of installation of the NVM/301 moni-
tor module or of the NC/321 hands free modu-
le in a unified recessed box of three modules
with a number of plates on the market (figures
12-13).
VIDEO ENTRY PANEL HEVC/301
The embedding box must be fitted flush with the wall
and at an height that ensure optimal camera opera-
tion. Fit the spacer into embedding boxes to avoid
deformation (fig. 14).
