APPLICATION
The VH30AK series video-intercom system allows any
number of VH30AK series inside handset sta-
tions to communicate with one or more door entry stations
with (or without) a built-in B&W camera. When used as
an apartment video-intercom system, the VH30AK can
view the caller, speak with the caller, and activate an
electric door release (if required).
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 codes.
5. Apply power and check system operation.

plugged into an accessible source of 117 VAC, preferably
within 50' (15 meters) of the VCU6 system power supply
unit(s), but no closer than 3 feet (1 meter).
ELECTRIC DOOR OPENER (OPTIONAL)
The DO-001 (or equivalent 12-16VAC type) electric door

WIRING
INSIDE HANDSET STATIONS
Run 2 conductor #18AWG (common), 4 conductor
#22AWG (common), RG59/U (common) and 1 conduc-
tor #22AWG (selective) cable from video handset
to video handset to the central equipment location
(where the VCU6 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.
RG59/U coax cable must be good quality, ALL COPPER,
with minimum 95% copper braiding. As with all systems,
we recommend running some spare wires, for future use.
Route cable away from AC power wiring, transformers,
fluorescent lights, light dimmers or other electrical de-
vices. Protect cable from damage. Shielded cable should
