Installing Accessories

Once you have installed your basic MERLIN system, you may want to add
accessories to enhance your system's capabilities.

FEATURE ACCESSORIES

With a Services Module in your control unit, you can add features such as
Music-on-Hold, Loudspeaker Page, Extra Alert, and Power Failure Transfer
telephones. To add a Services Module and related accessories to your system,
follow the instructions that come with the module.
Also available are headsets, headset adapters, and Hands-Free Units for your
voice terminals, as well as accessories that make it possible for you to connect
modems, autodialers, and answering machines to your voice terminals.

POWER ACCESSORIES

You may find it necessary to add auxiliary power components to your system.
For example, you'll need a Voice Terminal Power Supply for every 34-button
deluxe voice terminal connected to an accessory, for every attendant console
with an Attendant Intercom Selector, and for every voice terminal more than
1000 feet from the control unit. If you have an expansion unit, and if you have
more than 20 outside lines and more than 60 voice terminals, you'll also need
a Supplementary Power Module. And you may need as many as three Auxiliary
Power Units for your control unit and expansion unit if one or more of the follow-
ing conditions exist in your office:
You have the maximum number of voice terminals connected to your
system (30 for Model 1030 and 70 for Model 3070).
You have several voice terminals with accessories (and the voice terminals
do not have a Voice Terminal Power Supply).
There are long wiring runs between your control unit and your voice
terminals.
The lights on some of your voice terminals become dim or go out altogether
when many employees use their voice terminals simultaneously.
A system with many voice terminals and accessories may require one or more
Auxiliary Power Units. The graph, right, can help you determine if you need addi-
tional power components and, if so, how many you need.
To determine if the Power Module in slot number 1 in the control unit needs an
Auxiliary Power Unit, do this:
1. Count the voice terminals and Hands-Free Units connected to the Voice
Terminal Modules in your control unit, and add the two numbers
together. (Do not count 34-button deluxe voice terminals or voice ter-
minals that have a Voice Terminal Power Supply.)
2. Count the 34-button deluxe voice terminals connected to the Voice Ter-
minal Modules in your control unit. (Do not count 34-button deluxe voice
terminals that have a Voice Terminal Power Supply.)
3. Plot the two numbers from steps 1 and 2 on the graph as shown. This
will tell you if you need an Auxiliary Power Unit (or perhaps two) for your
control unit.
EXAMPLE: If you have twenty 10-button voice terminals, ten Hands-Free Units,
and ten 34-button deluxe voice terminals connected to the Voice Terminal
Modules in your control unit, the graph shows that you need one Auxiliary Power
Unit for the Power Module in slot number 1.
To determine if the Power Module in slot number 16 in your expansion unit needs
an Auxiliary Power Unit, repeat steps 1, 2, and 3, above, for the expansion unit,
but do not count voice terminals, Hands-Free Units, or 34-button deluxe voice
terminals connected to the Voice Terminal Module in slot number 24 (slot
number 26 if your system has Feature Module 3).
NOTE: It's highly unlikely that a Power Module in slot number 27 would require
an Auxiliary Power Unit.
If you have one Auxiliary Power Unit connected to a Power Module, plug it into
the leftmost auxiliary power supply jack on the module.
Depending on how many voice terminals and accessories you have connected
to your system, it may be more economical to provide Voice Terminal Power
Units for individual voice terminals rather than to provide Auxiliary Power Units
for your control unit or expansion unit. Your equipment supplier can help you
make the most cost-effective addition to your system.
If you know you need additional power supplies, do not use all your accessories
until you can provide enough power to your system. To add power supplies and
other accessories to your system, carefully follow the instructions that come
with the components.
