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(s)

Locate door entry station(s) at a convenient speaking

location at the building entry location(s).NOTE: For best

picture (video) quality DO NOT POINT CAMERA

INTODIRECTSUNLIGHT!!!

SYSTEM TRANSFORMER(s)

The SS146 (and T1240) system transformers may be

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

release is installed in the door jamb in place of the regular

door strike plate. It can be electrically operated by the

VH30AK video monitor+handset station(s).

WIRING

INSIDE HANDSET STATIONS

Run 2 conductor #18AWG (common), 4 conductor

#22AWG (common), RG59/U (common) and 1 conduc-

tor #22AWG(selective)cablefromvideomonitor+handset

tovideomonitor+handsettothecentralequipmentlocation

(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

the camera to the monitor. Starting at camera, check for video signal through coax cable, and through (VDU-4) video distributors (if used). Check for approx. 12VDC power at each VDU-4 video distributor (if used). Check coax connector at camera(s) to make sure it is not shorted or open. Temporarily switch monitor PC board (VH250P) with one from a functioning location. PLEASE NOTE: If these checkpoints fail to indicate the problem, there may be an equipment or wiring fault.

General Monitor Mounting and Wiring Information Note: There are Black and Red pigtail wires coming from terminals 'O' and 'LL' on the VH250P P.C. Board. The Black 'O' wire must jump to terminal 'O' on the monitor handset and the Red 'LL' wire must jump to terminal 'S' on the monitor handset or the monitor will not activate when the handset is signalled from the entrance station(s).
