GENERAL INFORMATION
The following general procedures must be observed in relation to the location
and installation of System One Home Communication components:
Stations are not to be installed “back to back” or in “line of sight”
of each other as this will cause feed-back (squealing).
Where stations are to be fitted externally, appropriate measures
to provide protection from weather are to be taken.
Avoid running Intercom cable in parallel to electrical wiring.
The Power supply is not to be installed in a cavity wall or any area
(roof etc) where temperatures are likely exceed 86º F.
Guidelines for maximum cable lengths as set out in this manual are to be
observed to avoid the possibility of operating problems due to excessive
voltage drop.
The maximum number of stations on a system including Master, Room and
Door stations is generally limited to 20. It is important that the power supply
is properly matched to the size of the system. (See Power Supply Page 25)
CAUTION: Failure to use Valet cable may cause problems with the
performance of the system and will void warranty on the
equipment.
IMPORTANT: Responsibility will not be taken for problems that arise from
the improper use of cable or interference generated externally
to the system.
Interference by light dimmers, fluorescent lighting and similar
electrical products, must be corrected at the source.
An aid to reducing the effects of this type of interference is to
place stations and wiring no closer than (12”) from any
AC device or wiring.
The circuitry of the intercom has been designed to minimize
the effects of Radio Frequency Interference however total
immunity to this type of interference cannot be guaranteed
where the levels of interference generated are extreme.

LOCATION OF EQUIPMENT
Master Station (Optional, Special Order Only)
Where a master has been purchased as part of the system, it is generally located
above the breakfast bar in the kitchen/family room at a suggested height of 55”
from the floor to the center of the unit. As all wiring from other stations
is generally terminated at the rear of the master, the walls should be no less than
2 ¾” in depth. A timber wall box should be inserted so as to allow for
correct support of the master station.
IMPORTANT
The master station should be installed in a cavity wall and not a single
brick wall in order to facilitate the wiring behind it.
Where there is wall tiling around or near to the master station, ensure the master
station is mounted either completely within or completely clear of the tiled area
as failure to do so will result in the master being affixed to an uneven surface.

4
Room Stations
Careful consideration must be given to present and/or future layout of
furniture so as not to locate stations in inappropriate positions.
To avoid audio feedback, room stations should be kept at least 12 to
16 feet away from other stations. Never have more than one station
in any one room and avoid mounting stations in the same wall cavity
i.e. directly below and above one another in a two storey house.
A suitable height is generally 55” from the floor to the center
of the unit.
Stations located on timber frame walls should be located adjacent to a
stud to allow for firm fixing.
Stations located on cavitybrick walls will require the installation of wall
boxes.
Stations installed on single brick walls will also require wall boxes however
the cable will need to be chased and conduited into the brick wall.
The rear of the brick wall will need to be rendered or lined as the depth
of a room station is approximately the same as a brick.
Where stations are required in bathrooms or laundries, they must be kept
clear of water or steam.
Where stations are mounted on a tiled surface, a wall box should be
installed prior to lining/tiling of the walls and the tiles will need to be cut
to the inside dimensions of the wall box.
Where room stations are mounted outsideand are exposed to the
weather, the fitting of weather proof covers will be required.
Stations must not be installed in saunas.

5
Front Door/Gate Station(s)
These stations are best located adjacent to the front door or at the front
gate at a suggested height of 55” and may require a wall
box depending upon the surface to which they are to be affixed.
Any Station exposed to the weather will require the fitting of a weatherproof
cover.
Where stations are to be installed in solid brick or concrete columns at a
front gate, it is required that the cable be run in conduit from the station
to ground level and back to the house.
Power Supply
The power supply is usually located no less than 6 feet and not more
than 16 feet from the point of connection at the System One Room Station.
Suggested locations are kitchen cupboards, pantry, bedroom wardrobes etc.
Because the power supply dissipates heat more effectively in a cool
environment it is recommended that the supply not be located in the
roof space of a dwelling. It is also advantageous to have easy access
to the supply should it be required that the system be turned off.
Antenna (AM/FM Aerials)
The antenna arrangement is a critical part of the installation if
a quality radio reception is required.
The AM and FM aerials should be located in the highest point of the
roof and at least 6 feet away from any electrical or intercom
wiring.
Because the FM antenna is directional, experimentation with
positioning is recommended to achieve the best possible result.
Where the roof is lined with foil insulation or is of metal construction,
an external whip or car radio antenna may be required for AM.
Connecting a specialized FM antenna or connecting to a TV antenna
can greatly improve FM reception in poor signal areas.

6
Auxiliary Input Jack
Optional accessory allowing music from an external source such as a Tape Deck,
CD player or walkman to play throughout the Intercom System.
Two different types of Input Jack are used: -
Type A - For use with a Master
Type B - for use without a Master
The Input Jack should be installed in a wall near the location where
the external music source is to be situated.
NOTE: An appropriate lead will be required to connect the music source
to the Input Jack.
The use of appropriate cable from the Input Jack to the master (or from
the Input Jack to a room station where a master is not used) is essential.
See section ‘What CableTo Use’.
Auxiliary/Lock Output Board
Optional Accessory allowingElectronic door locks, Automatic gates, Courtesy lights,
Alarm panic circuits, etc. to be controlled from the Master or any Room station.
There are two (2) outputs on each board which can individually be
programmed to time out or toggle depending on the application.
Four (4) of these boards can be fitted to any one system allowing a total
of eight (8) Auxiliary outputs in total.
Each board is fitted in conjunction with a room station and is located
in the side compartment of the room station back housing.
NOTE: Additional wiring is required for this feature to be available.
See section ‘What CableTo Use’.

7
WHERE TO RUN CABLE
Cables can be run either:
In the roof space
In false ceilings/bulkhead area
Through and/or around external walls
Under floors (subject to access being available)
Note: Intercom cables should be run as far away from AC wiring as
practicality permits.
Avoid running intercom cable in parallel to AC or any other type of
wiring. (Running across at right angles is OK where necessary)
All aerial wires should be taken to the highest and most accessible
point in the roof.
Allow additional cable ateach station for the purpose of termination.
(At least 3feet )
In the case of cavity brick walls, ensure the wires are pulled through
one of the holes at the rear of the wall box.

WHAT CABLE TO USE ?
General
System One is designed to operate using8 core cable however operation is also
possible using 6 core cable with the disadvantage that music will be muted at all
room stations while private communication is in progress.
The system may be Star Wired from a central point or Loop Wired however the
number of stations on a loop is governed by the length of the loop, and also
whether or not a standby battery is being used in conjunction with the supply.
See section “Maximum Cable Lengths”.
Important Note: Different cables have different characteristics hence it is
recommended that ‘Valet Cable’ be used on all new installations. Many other
cables will work acceptably HOWEVER RESPONSIBILITY CANNOT BE TAKEN
FOR PROBLEMS THAT ARISE FROM THE USE OF OTHER CABLES.
The proper use of shielded cable on VLC & TC terminals will prevent “clicks & pops”
caused by Control Voltage changes from being induced onto audio lines.
Power Supply
Heavy duty ‘Figure 8’ cable (18 gauge or better) should be run from the Power
Supply to the System One Room Station.
AM Aerial
The coaxial cable supplied with the master is to be run from the master to the
highest point in the roof where the antenna tail provided (or a car radio antenna)
must be plugged into the socket at the end of the cable. The plug at the master
end of the cable must be cut off. Additional AM coax leads can be plugged into
one another if additional length is required.
FM Aerial
Run the 300 ohm FM Ribbon antenna supplied with the master from the master
to the highest point in the roof. If using coaxial cable to connect to an alternative
75 ohm antenna, be sure to fit a balun to the 300 ohm terminals at the master.

9
Auxiliary Input Jack [Optional]
Two different Input Jacks are available, each requiring different cabling.
Type ‘A’ ( For use with a system incorporating a master) (Special Order Only)
Run ‘2 core’shielded audio cable from the master to the Input Jack.
Type ‘B’ (For use with systems not incorporating a master)
Run 6 core cable (or same wire as used for intercom wiring) from
Input Jack to the nearest room station.
Auxiliary/Lock Outputs [Optional]
An additional single core cable is required between all room stations
(and master if fitted).
Heavy duty ‘Figure 8’ cable (18 gauge or better) is to be run from
each relay output (via power source if applicable) to each auxiliary device.
Note: Clearly tagging all cables at the master or central wiring point is
recommended, as this can be extremely helpful in the event of having
to isolate a problem such as a damaged cable.
