Installing Accessories

Once you have installed your MERLIN system, you may want to add ac-
cessories to enhance its capabilities.

CARTRIDGES

Cartridges provide the software and interfaces that make it possible for you to
use many of the MERLIN system features and accessories. With Type I car-
tridges, called Feature Packages, you can have access to features such as Con-
ference Calling, Call Pickup, Call Transfer, and Outward Call Restriction.
Without any cartridges you still have standard features, which include Automatic
Line Selection, Hold, and Intercom. Type II cartridges provide Music-on-Hold
and Loudspeaker Paging capabilities. Type III cartridges provide Extra Alert
and Power Failure Transfer capabilities. See page 15 for information on inser-
ting cartridges in the control unit.

ACCESSORY EQUIPMENT

General Purpose Adapters allow you to connect Touch-Tone (not rotary) equip-
ment such as modems, autodialers, and telephone extensions (including cor-
dless telephones) to your voice terminals.
Supplemental Alert Adapters enable you to connect alerting devices such as
horns, bells, and strobe lights to your system.
If you need to add one or more voice terminals or outside lines to your system,
add a 2-Line Module, a 5-Voice Terminal Module, or a 2-Line/5-Voice Terminal
Module to your control unit.

POWER ACCESSORIES

You may find it necessary to add auxiliary power components to your system.
For example, you may need a Voice Terminal Power Supply for a 34-button
deluxe voice terminal with an accessory connected to it or for a voice terminal
located more than 1000 feet from the control unit. Or you may need an Aux-
iliary Power Unit for your control unit if many of your voice terminals have an
accessory but do not have a Voice Terminal Power Supply.
If the lights on some of your voice terminals become dim or go out altogether
when many employees use their voice terminals at the same time, you probably
need one or more auxiliary power components. If you know you need additional
power, do not use all your accessories until you can supply enough power to
your system.
It may be more economical to provide Voice Terminal Power Supplies for your
voice terminals than to get an Auxiliary Power Unit for your control unit. Your
equipment supplier can help you make the most cost-effective addition to your
system.
To add power and other accessories to your system, follow the instructions that
come with the components.
