Introduction

This installation guide tells you how to install and test your

MERLIN® communications system, Model 820. It leads you step by step

through system installation, from a pre-installation checklist to system tests.

You should perform the steps in the order in which they are presented because

many of the earlier steps prepare the system for the later steps.

When you complete the steps in this guide, you will be ready to customize the

system to meet the needs of your business. If you have a Feature Package, refer

to the administration manual that comes with it for administration and program-

ming instructions. Your system may not be fully operable until you have pro-

grammed and administered it.

This guide consists of the following sections:

●

Getting Started tells you how to prepare for system installation.

Preparing the Network Interface

shows you how to prepare the connec-

tion to your outside telephone lines.

Installing the Control Unit explains how to set up and connect the

system’s control unit.

Voice Terminal Wiring

tells you how to install the wiring for your voice ter-

minals

(MERLIN

system telephones).

Connecting the Voice Terminals

tells you how to connect your voice ter-

minals to the system and test them.

Installing Accessories

describes some of the accessories that you may

want to add to your system and explains when it may be appropriate to

install these accessories.

System Tests

provides tests to make sure you’ve installed your system

properly.

What’s Next?

refers you to documents that describe how to customize and

use your system.

System Changes

describes how to rearrange or alter your system once

it is in place.

Troubleshooting

isolates and identifies specific problems that could arise

during system installation, and suggests solutions to basic problems.

The steps in this guide are numbered in order of performance. To visualize a

step as it is described, refer to the pictures accompanying the text. The numbers

in the drawings correspond to the step numbers in the text.

Getting Started

This guide assumes the tasks on the following list have been completed. Review

the list carefully. If you have not completed the tasks on the list, you should do

so now.

●

Check the items in your shipment against your copy of the order form.

Make sure the items and quantities agree. Save the instructions that come

with each component, and also keep the packing boxes just in case you

have to return components under warranty.

Get acquainted with the system environment.

Review the planning sheets you drew up when you ordered the system.

Confirm the voice terminal and control unit locations, and make sure the

control unit location meets the following environmental standards:

—

Operating temperatures: 40 to 104°F (4 to 40°C).

—

Humidity: not to exceed 80%.

—

Ventilation: Leave 6 inches of space above and to the sides of the

control unit. Keep the control unit away from sources of extreme heat

(furnaces, heaters, attics, or direct sunlight). Do not stack multiple

control units in rooms that are not air-conditioned; install them side

by side at least 6 inches apart.

—

Airborne contamination: Do not expose the control unit to moisture,

corrosive gases, dust, chemicals, or similar substances.

If the control unit location does not meet these standards, your warranty

may become void.

●Become familiar with the MERLIN system.

Review the drawing of a simple

MERLIN

system configuration, opposite

page, and note how components are related to one another.

NOTE:

The

cartridges

and

modules

it contains pro-

vide the power and the intelligence for all voice terminals and

accessories.

Modular jumper cords

connect the control unit to jacks in the jack

field.

The

jack field

serve as an interface between the control unit and

the building wiring.

Building wiring ties the whole system together, connecting the

voice terminal locations to the control unit location.

Modular wall jacks connect the voice terminals to the building

wiring.

Modular voice terminal cords

connect the voice terminals to the

modular wall jacks.

Voice terminals provide telephone functions and access to the

advanced features in the control unit.

The

network interface,

shown here extended to the jack field, pro-

vides the connection to the local telephone company lines.

Line cords

connect the control unit to the network interface or, as

shown, to the jacks in the jack field for the outside telephone lines.

The ac outlet is the electrical power source for the control unit.

Modular jumper cords are identical to modular voice terminal

Make sure your system wiring is in place.

You must have wiring that connects your voice terminal locations to your

control unit location. If your voice terminal locations are close enough to

your control unit to make direct connection practical, you are probably plan-

ning to connect your voice terminals directly to the control unit with modular

voice terminal cords and, if necessary, modular voice terminal extension

cords. If you are planning to connect your voice terminals directly to the

control unit, this guide tells you how to do so at the appropriate place in

the installation sequence.

If conditions at your business make direct connections between your voice

terminal locations and your control unit location impractical, then you have

connected the locations through the building wiring. You may have had

the necessary wiring professionally installed, or perhaps you did the wir-

ing yourself following the instructions that came with the Wiring Installa-

tion Kit. In either case, you should now have building wiring that runs from

the voice terminal locations to the control unit location. The wiring runs

should end in modular wall jacks at the voice terminal locations and in a

group of jacks mounted in jack panel boxes (the “jack field”) at the con-

trol unit location. Inside the right door (the one with the handle) of each

jack panel box you should find a label indicating the wiring run number

and endpoint location (for example, “w1 Reception area”) for each jack

in the jack field.

tions and locations in the system.

You must also have a network interface that links your system to the local

telephone company’s lines. A telephone company representative should

have installed the necessary outside telephone lines and labeled the net-

work interface to indicate the telephone number for each outside line.

Depending on the type of interface provided by the telephone company,

your system may require additional wiring running from the network in-

Control unit

terface to the jack field.

If you had your building wiring and jack field professionally installed, you

probably had the wiring from the network interface to the jack field installed

at the same time (if it was necessary). But if you prefer to install the wiring

from the network interface to the jack field yourself, this guide tells you

how to do so in “Preparing the Network Interface:” page 7.

The drawing, top right, shows direct connections between a voice terminal

and the control unit, and between the network interface and the control

unit. The drawing, bottom right, shows a voice terminal connected to the

control unit through the building wiring and a jack field. It also shows ad-

ditional wiring extending the outside lines from the network interface to

To comply with FCC regulations, notify your local telephone company of

the following before permanently connecting your system to their lines:

—

System registration number: AS 593M-13529-KF-E

—

Ringer equivalence number: 0.8A

—

Preparing the Network Interface

The local telephone company should have installed a network interface with

1-line jacks (RJ11-type), 2-line jacks (RJ14-type), or a multiline connector

(RJ21-type) for connecting your MERLIN system to your outside telephone

lines. The drawing, right, shows the three types of interfaces and the 2-line

adapter (267C) for the 2-line network interface jack. The table, on page 8, tells

you what to do next depending on the type of network interface you have.

EXTEND THE NETWORK INTERFACE TO THE JACK FIELD

You need the following to extend the network interface to the jack field:

●4-line adapter

If you have more than four outside lines, you need two 4-line adapters.

●Jack panel box

●Green-on-white label sheet

●Single-ended 25-pair connectorized cable

The drawing, right, shows a 4-line adapter (Z610A), a 25-pair connectorized

cable, and a jack panel box (Z122C). A drawing of the green-on-white label sheet

appears on page 12. You also need a jacket-stripping tool to slit the jacket on

the 25-pair cable and a cable termination tool to punch the wires down onto

the block(s) on the 4-line adapter(s). Your equipment supplier or technical con-

sultant can help you obtain these items. 4-Line adapter
