VH30ANC 'NoCoax' Video
Monitor Station (shown)
APPLICATION
The VH30ANC series 'NoCoax' video-intercom system
allows any number of VH30ANC series inside
monitor+handset stations to communicate with a single
door entry station with (or without) a built-in B&W
camera. When used as an apartment video-intercom
system, the VH30ANC can view the caller, speak with
the caller, and activate an electric door release (if re-
quired).
PROCEDURE
1. Read installation instructions for each unit to deter-
mine equipment location and installation method.
2. Install housings and wiring.
3. Install equipment.
4. Check wiring and connect. Observe all local
and national electrical and building codes.
5. Apply power and check system operation.
VH30ANC Series (B&W Apartment Type)
'NoCoax' Video-Intercom Installation
and Use Instructions, used with the
VCU309 System Power Supply Unit(s)
HOUSING INSTALLATION AND
EQUIPMENT LOCATION
INSIDE MONITOR+HANDSET STATION(s)
Locate stations where needed at convenient speaking and
viewing height, about 4.5 feet (137 cm) from the finished
floor. Unit can be secured directly to the finished wall
surface or can be mounted over a single gang electrical
'gem' box or single gang electrical plaster ring.
DOOR ENTRY STATION
Locate the door entry station at a convenient speaking
location at the building entry location. NOTE: For best
picture (video) quality DO NOT POINT CAMERA
INTODIRECT SUNLIGHT!!!
SYSTEM TRANSFORMER(s)
The T2440 24VAC system transformer(s) may be plugged
into an accessible source of 117 VAC, preferably within 50'
(15 meters) of the VCU309 system power supply unit(s),
but no closer than 3 feet (1 meter).
ELECTRIC DOOR OPENER (OPTIONAL)
The DO-001A (or equivalent 12-16VAC type) electric door
release is installed in the door jamb in place of the regular
door strike plate. It can be electrically operated by the
VH30ANC video monitor+handset station(s).
WIRING
INSIDE MONITOR+HANDSET STATION(s)
Run 4 conductor #22AWG (common) and 1 conductor
#22AWG (selective) cable from video monitor+handset to
video monitor+handset to the central equipment location
(where the VCU309 unit is found). Additional cables may
be used to serve other monitors on other risers (lines).
Cables may be straight or twisted pair type and may be
solid or stranded conductors. Depending upon additional
system options and/or functions you may need to run
additional wires. Please consult the factory for more
information. As with all systems, we recommend running
some spare wires, for future use.
Route cable (and all central equipment) away from AC
power wiring, transformers, fluorescent lights, light dim-
mers or other electrical devices. Protect cable from
damage. Shielded cable should be used if AC interference
is a concern, or if cables cannot be run adequately spaced
away from any source of electrical interference.

OPERATING INSTRUCTIONS
TO PLACE A CALL TO THE REMOTE
MONITOR+HANDSET UNITS:
At the remote door entrance station, depress button (for a
few seconds) for apartment you wish to call. This will signal
the Alphatone™ signal at the apartment monitor handset,
and will cause the video screen to light and display the visitor.
The tenant may choose to ignore the caller, or to lift the
intercom handset to answer. Tenant may speak to the visitor
by simultaneous 2-way (DUPLEX) voice. If tenant is
satisfied with identity of caller and wishes to let visitor into
the building, tenant shall momentarily depress the door
release (KEY) button on the handset, which will electrically
activate the door release mechanism.
Monitor will time-out automatically after approx. 40 seconds
(unless the time-out duration has been changed by the
installer/user).
TROUBLESHOOTING
If the system fails to operate as required, review operating
instructions again. If the equipment fails to operate as
indicated in the instructions, check the following points:
1. ENTIRE SYSTEM DEAD: Check for 24VAC at the
T2440 secondary and 12VAC at the T1240 secondary;
wiring between transformer(s) and power supply unit(s);
connections at main power supply units, 117VAC at
transformer primaries. Check for 20VDC (output) across
terminals (+) and (-) on the VCU309 power supply.
2. NO CALL UP TONE AT HANDSET: Check that
the 50-ohm speaker in the handset base is functioning.
Temporarily switch handset with one from a functioning
location. Check wiring connections at remote handset.
Check that entry station pushbutton is making contact,
by shorting out the two (2) wires on the back of the
button.
3. NO PICTURE AT MONITOR: If screen is NOT
LIGHTING UP, check for approximately 20VDC at
(+) and (-) terminals on monitor PC board (VH309B).
Check Brightness and Contrast controls on front of
monitor. If screen IS LIGHTING UP but there is no
picture, you probably are not getting a video signal from
the camera to the KBS-1 converter. Starting at camera,
check for video signal through coax cable. Check for
approx. 15VDC input power at each VBV-4 video data
distributor (if used). Check coax connector at entry
camera to make sure it is not shorted or open. Tempo-
rarily switch monitor PC board (VH309B) with one
from a functioning location. Make sure input voltage on
the KBS-1 is 15VDC and not 12VDC.
DOOR RELEASE
Run 2 cond. #18 from the door release location to the
NH209TTA speaker/microphone assembly. Route away
from any station wiring. Note: if wire run is longer than 50 feet
(15m), use #16AWG cable.
CONNECTIONS
Before connecting, make certain wires are free from shorts
or grounds. Make connections as shown on the enclosed
system diagrams, and as indicated below.
NOTE: Please keep in mind that all wiring terminals
shown may not be in the actual order in which they
appear on the equipment. This is done for clarity of
wiring diagram purposes.
TRANSFORMER
1. Connect the 24VAC (T2440) transformer to the VCU309
power supply, where indicated. Do not use transformer(s)
to power any other device(s).
2. Connect the 12VAC (T1240) transformer to the
NH209TTA speaker/microphone assembly, where indi-
cated. Do not use transformer(s) to power any other
device(s).
3. Do not connect transformer primary to 117 VAC until
entire installation is complete and all wiring is checked.
DOOR RELEASE
1. Connect the 12-16 VAC electric door opener using 2
conductor #18AWG (polarity not important). Route away
from any station wiring. Note: if wire run is longer than 50
feet (15m), use #16AWG cable.
FINISH INSTALLATION
1. Install all components. Do not overtighten screws.
2. Connect primary of all transformers to 117 VAC.
Observe all local and national electrical codes.
TEST AND CHECKOUT
1. At all remote monitor+handset stations, make certain the
handsets are completely hung-up on the handset cradle.
2. Check each monitor+handset unit in the system for
operation in accordance with the operating instructions.
3. Check for proper door release function (on systems with
door release capability.
NOTE: System warranty is void if this system is installed
or used in any manner other than described in this
manual.

4. NO VOICE ON SYSTEM: Check volume control
potentiometer(s) on NH209TTA speaker/microphone
(in both directions; up and down). Check speaker/
microphone connections at entry station. Connect a
single handset to system wiring only, to test voice
operation. If voice is working, amplifier and entry
speaker/microphone are O.K., so check riser wiring. If
not, amplifier or speaker/microphone could be faulty.
Check by replacement.
5. UNABLE TO RELEASE DOOR STRIKE: Check
operating voltage of door opener so it matches 12VAC
output from NH209TTA system amplifier. Check wir-
ing (and gauge) to door opener, from amplifier/power
supply. When using a magnetic type lock or other 'fail-
safe' type door strike, or other voltage door strike, you
should use a reversing/specialty relay, such as our model
#PK407A for each entrance door strike or door lock.
6. HUM OR BUZZ: Check system wiring installed too
close to power wiring or electrical devices or transform-
ers; check transformer(s) installed too close to control
equipment (should be at least three (3) feet away).
Wiring is being run next to wiring for other systems and/
or devices.
7. MONITORS TIMING OUT TOO QUICKLY:
Check adjusting control potentiometer on VH309B PC
board and adjust as needed from approx. 0 to 180
seconds. Calibration is not exact, so please check timing
after re-adjusting.
8. MONITORS DO NOT TIME OUT AT ALL:
Check for shorts and/or grounds on system. Tempo-
rarily switch monitor with one from a functioning loca-
tion. Check that entry station pushbutton is not stuck or
shorted.TemporarilyswitchmonitorPCboard(VH309B)
with one from a functioning location.
9. VIDEO PICTURE POOR QUALITY: Make sure
KBS-1 is installed as close to entry camera as possible.
Make sure there is a 100 ohm (model RC0100/4) end-
of-line resistor across terminals 'Y' and 'Z' at the end of
each video/data riser/line.
PLEASE NOTE: It is normal for the KBS-1 unit
to get very warm, when operating. Please take
care not to touch any warm or hot components
with your bare hands! If these checkpoints fail
to indicate the problem, there may be an equip-
ment or wiring fault. Please contact the factory
or a qualified service representative for addi-
tional assistance.

THESE ARE LOW VOLTAGE DC POWERED CAMERAS AND THEY ARE POLARITY SENSITIVE.
THE POLARITY IS AUTOMATICALLY CORRECT WHEN THE POWER SUPPLY MODULE IS PLUGGED DI-
RECTLY INTO THE CAMERA USING THE FACTORY INSTALLED CONNECTORS. IF IT IS NECESSARY TO
EXTEND THE DISTANCE BETWEEN THE POWER MODULE AND THE CAMERA, CUT AND SPLICE THE
WIRE ON THE POWER MODULE ONLY. IF IT IS NECESSARY TO REMOVE THE POWER CONNECTOR OR
CUT AND EXTEND THE POWER CABLE, IT IS VERY IMPORTANT TO MAKE SURE THAT THE POLARITY
IS CORRECT BEFORE POWER IS SUPPLIED TO THE CAMERA. USE A METER TO CHECK THE POLAR-
ITY OF THE NEWLY SPLICED CABLE BEFORE CONNECTING IT TO THE CAMERA.
THE CENTER PIN MUST BE POSITIVE!
USE ONLY THE SUPPLIED POWER SUPPLY! POWER SUPPLY IS FOR INDOOR USE ONLY.
DO NOT REMOVE THE SERIAL NO. STICKER, AS THIS WILL VOID THE WARRANTY.
