VH30ANC 'NoCoax' Video
Monitor Station (shown)
APPLICATION
The VH30ANC series 'NoCoax' video-intercom system
allows any number of VH30ANC series inside
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.

and Use Instructions, used with the
VCU309 System Power Supply Unit(s)
HOUSING INSTALLATION AND
EQUIPMENT LOCATION
INSIDE 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
INTO DIRECT 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 handset station(s).
WIRING
INSIDE HANDSET STATION(s)
Run 4 conductor #22AWG (common) and 1 conductor
#22AWG (selective) cable from video handset to
video 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.
