General Information - Valet System One Installation Instructions Manual

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:
IMPORTANT:
Failure to use Valet cable may cause problems with the
performance of the system and will void warranty on the
equipment.
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.
