Entryphone 500 Series equipment is designed to enable video systems to be installed on
standard audio wiring. The video, speech, signalling and power are on ve common conductors
to every part of the system.
There are two very important things that must be done to ensure a system works well.
1. The video signal is balanced and therefore termination jumpers must be inserted at line
ends or removed from mid-line equipment.
Schematics and wiring diagrams show when jumpers should be tted.
NOTE: If, on test, a video screen seems over bright or washed out it is likely that the line
has not been terminated properly, either a jumper is inserted mid-line or missing at the
end of the line.
2. There are no individual call lines for the 500 series systems, instead each phone has a
switch setting that should be set when the telephone is installed.
The phone's address is set as a binary number on an eight way DIL (dual in-line) switch
(up to 255 addresses available) tted in each phone. When planning a system it is good
practice to determine which address is to be assigned to which phone and noted on the
numbering sheet on page 14 of these instructions.
System Layout
Whether installing a system on existing or new wiring it is best to determine the layout of the
cabling and positions of the apparatus before starting the installation. There are a number of
layout examples and their corresponding connection diagrams in this booklet.
Please make a note of the phone codes and sketch the layout of the system on pages 14 and 15
of this booklet. Leave this booklet with the installed system.
