Introduction
This installation guide tells you how to install and test your MERLIN™ com-
munications system, Model 1030 or Model 3070. 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 later steps.
When you complete the steps in this guide, refer to the Administration
Manual: Models 1030 and 3070 (packed with your Feature Module) for program-
ming and administration instructions. Your system may not be fully operable until
you have programmed and administered it.
This guide consists of the following sections:
●

Getting Started reviews preparation for system installation and includes
a diagram of a simple MERLIN system configuration, identifying com-
ponents and showing them in relation to one another.
Preparing the Network Interface tells you how to prepare the connec-
tion to your outside telephone lines.
Installing the Control Unit tells you how to set up and connect the con-
trol unit.
Connecting Voice Terminals explains how to connect the voice terminals
(telephones) to the system.
Installing Accessories suggests some accessories you may want to con-
sider adding to your system and when you should consider installing them.

Getting Started
This guide assumes the tasks on the following list have been completed. Review
the list carefully before proceeding with system installation. If you have not com-
pleted the tasks on this list, do so now.
●
Check the items in your shipment against your copy of the order form.
Make sure the items and quantities agree. Be sure to keep the instructions
that come with each component, and also keep the packing boxes so you
can easily return equipment under warranty if necessary.
●
Get acquainted with the system environment.
Review the planning sheets you drew up when you ordered the system.
Confirm the voice terminal locations, and make sure the control unit loca-
tion 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 to prevent overheating. 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 control unit and the modules it contains provide the power
and the intelligence for all voice terminals and accessories.
An expansion unit increases your system’s capacity from 10 out-
side lines and 30 voice terminals to 30 outside lines and 70 voice
terminals.
Modular jumper cords connect the jacks on the Voice Terminal
Modules in the control unit to jacks in the jack field.
The jacks in the jack field serve as an interface between the con-
trol unit and the building wiring. In some configurations, additional
jacks in the jack field connect the system to its outside telephone
lines.
Building wiring ties the whole system together, connecting the
voice terminal locations to the jack field at the control unit location.
Modular jacks terminate the building wiring at the voice terminal
locations.
Modular voice terminal cords connect the voice terminals to the
modular jacks.
Voice terminals provide telephone functions and access to the
advanced features in the control unit.
The
ac outlet is the electrical power source for the control unit.
The
network interface jacks provide connections to the local
telephone company lines.
Line cords connect the control unit to jacks at the network inter-
face (or, if necessary, to jacks in the jack field).
Modular jumper cords are identical to modular voice terminal
cords. They have different names in this guide to reflect their different func-
tions and locations in the system.

Make sure your system wiring is in place.
The drawing, right, illustrates the wiring that must be in place before you
begin installing your system. You must have building wiring that runs from
the control unit location to the voice terminal locations. Wiring runs should
end in modular jacks at the telephone locations and in a group of jacks
mounted in apparatus boxes (the “jack field”) at the control unit location.
Each apparatus box should have a white label with blue numbers indi-
cating the numbers of the jacks in the box (1-6, 7-12, etc.). Inside the right
door (the door with the handle) of each apparatus box you should find a
white label lettered in blue to indicate the endpoint location (for example,
“workshop” or “Room 23”) of each jack in the jack field.
You may have your building wiring and jack field professionally installed
or you may install them yourself. If you choose to install your own building
wiring and jack field, follow the Wiring Installation Instructions included with
the Wiring Installation Kit.
You must also have a network interface that links your system with the local
telephone lines. A telephone company representative should have
installed the necessary outside telephone lines and labeled the network
interface to indicate the telephone number for each outside line. Depend-
ing on the type of interface provided by the telephone company, you may
have to run additional wiring from the network interface to the jack field
during installation in order to connect your system to your outside
telephone lines.
If you have your building wiring and jack field professionally installed, you
may want to have the wiring from the network interface to the jack field
installed at the same time (if it’s 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 the next section, “Preparing the Network Interface,”
page 5.
NOTE: The manufacturers, distributors, and their agents will not be
responsible for damage due to improperly installed wiring.
The FCC requires you to notify your local telephone company of the follow-
ing before permanently connecting your system to their lines:
—
System registration number
For systems with Feature Module 1, 2, or 4:
AS 593M-64884-MF-E
For systems with Feature Module 3: AS 593M-13529-KF-E

EXTEND THE NETWORK INTERFACE TO THE JACK FIELD
You need the following to extend the network interface to the jack field:
4-Line adapters
Apparatus boxes
Green-on-white line labels and directories
Single-ended 25-pair connectorized cables
The drawings, right, show a 4-line adapter, an apparatus box, and a 25-pair con-
nectorized cable. You also need a jacket-stripping tool to slit the jacket on the
25-pair cable and a cable termination tool to punch down the wires onto the
blocks on the 4-line adapters. Your equipment supplier or technical consultant
can help you obtain these items.
The table, below, tells you how many adapters, apparatus boxes, and cables
you need based on the number of outside lines you have.

Telephone company installers do not normally connect more than 24 out-
side lines to one 50-pin connector. But if you have exactly 25 outside lines, the
phone company may connect all 25 lines to a single 50-pin connector. If you
have exactly 25 outside lines and you find a single 50-pin connector at the net-
work interface, you need only one 25-pair connectorized cable to extend the
network interface to the jack field.

With a jacket-stripping tool, slit the jacket at the other end of the 25-pair
cable, and cut away as much of the jacket as necessary to allow each
of the individual twisted pairs of color-coded wires to reach the jacks
in the jack field. 1
Following the order and color code in the drawing, below, place the wires
in the terminal block grooves on the adapters.
Punch the wires down with a cable termination tool.

NOTE:
Find the green-on-white label sheet, which includes a telephone
number directory, line jack labels, apparatus box labels, and jack-
identifier label strips. If you have more than 24 outside lines, you need
two sheets.
Fill in the telephone numbers for your outside lines on the telephone
number directory in the order in which they appear at the network inter-
face or on the list provided by the local telephone company.
Using the telephone number directory as a guide, label the jacks with
the appropriate line jack labels.
Using the telephone number directory and the line jack labels as guides,
label the outside of the right door of each apparatus box with the appro-
priate apparatus box label.
Using the apparatus box labels as guides, label the inside of the right
door of each apparatus box with the appropriate remaining long, nar-
row label (jack numbers 1 through 8, 9 through 16, etc.).
Attach the telephone number directory to the outside of the right door
of the apparatus box labeled 1-8.
Each green-on-white label sheet has enough labels for 24 outside lines.

If you have more than 24 outside lines, get a second sheet and change the
numbers on the labels to reflect the numbers of your lines above 24. For exam-
ple, if you have 30 outside lines and you are labeling your fourth apparatus box,
take the apparatus box label for 1-8 from the second label sheet, cross out 1-8,
and write in 25-30. Then label your fourth box with that label. The second
telephone number directory goes on the apparatus box labeled 25-30.

Installing the Control Unit
You need the following components to install the control unit:
●
Control Unit Installation Kit
It comes with the control unit and includes line cord labels, jumper cord
labels, telephone location labels, five 7-foot line cords, and a system
directory.
●Control unit
It contains a Power Module (with a power cord), a Processor Module, a
Line Module, and a Voice Terminal Module.
●
Feature Module
It provides the system’s advanced features.
You may also need the following components, depending on the size and
specific makeup of your system:
●
●
Additional modules
They provide for additional outside telephone lines, voice terminals, stan-
dard telephones, off-premises telephones, and features such as Paging,
Music-on-Hold, and Power Failure Transfer.
Model 1030 Expansion Unit
This addition to the control unit expands your system’s capacity to 30 out-
side lines and 70 voice terminals.
NOTE: Feature Module 3 and, under certain conditions, Feature Module 4
change the system’s capacity. If you have Feature Module 3 or 4, see the admin-
istration manual that comes with the module.
10

POSITION THE CONTROL UNIT
Your control unit should be:
●High enough off the floor to work with comfortably
●
Close enough to an ac outlet (not switch-controlled) so that a power cord
can reach easily (with some slack) from each Power Module (you may have
as many as three Power Modules) to the outlet
●Within 5 feet of the jack field so that (1) a modular line cord can connect
any Line Module jack in the control unit to any jack with a green-on-white
label in the jack field, and (2) a modular jumper cord can connect any Voice
Terminal Module jack in the control unit to any jack with a blue-on-white
label in the jack field
The drawing, right, provides a diagram for positioning the control unit.
You may place the control unit on a table, a microwave oven stand, or a tele-
vision stand. Or you can order a Wall Mount Kit especially designed for wall-
mounting a Model 1030 or 3070 and follow the instructions that come with it.
NOTE: The ac outlet should be a 117-volt, 60-Hz, 3-prong, third-wire grounded
outlet. Proper grounding protects the system from damage caused by power
surges. You may want to have an electrician check the outlet’s third wire to make
sure the outlet is properly grounded. Power consumption for the Model 1030
control unit is 150 watts maximum. For the Model 3070, power consumption
is 400 watts.

IMPORTANT: A connected, loaded, but unpowered expansion unit can cause
electrical interference (crosstalk) during normal system operation. If you have
a Model 3070 control unit but do not need the control unit’s added capacity right
away, you should either (1) leave the expansion unit empty (do not insert any
modules) and leave the power to the expansion unit off or (2) put the modules
into the expansion unit, turn the power to the expansion unit on when instructed
to do so, and leave it on during normal system operation.

NOTE: Fill the slots in the control unit first, before going on to the ex-
pansion unit.
Remove the protective cover from the slot by pressing down on its top
with the tip of a screwdriver and pulling out at the top of the cover.
Align the module in the slot, making sure that the edges of the module
are in the grooves at the top and bottom of the slot, and slide the module
into the slot.
CAUTION: Do not force the module into the slot. If you have any dif-
ficulties, remove the module from the slot. Check the back of the
module and the back of the slot for bent pins. If you find any
damaged pins, contact your equipment supplier.

ATTACH CORD CLIPS TO THE CONTROL UNIT
If you have an expansion unit, you can have as many as 100 cords running from
your control unit to the jack field. You’ll want to arrange these cords as neatly
as possible without diminishing the system’s flexibility. Bundling the cords with
cord clips and cable ties can reduce the cord-clutter problem at your control
unit location.

Find the gray plastic cord clips with adhesive backs, and count out one
cord clip for each Line Module and two cord clips for each Voice Ter-
minal Module in your control unit (and expansion unit).
Attach cord clips along the front edge of the top of the control unit (and
expansion unit), one above every two Line Modules and one above each
Voice Terminal Module.
Attach the same number of cord clips along the rear edge of the con-
2
trol unit (and expansion unit), aligning them with the clips at the front
of the unit.
The next two sections include instructions for threading cords through the cord
clips.
TIP: If you have cord clips that open, you can open and close the clips when
the instructions tell you to thread cords through the cord clips.
CONNECT THE CONTROL UNIT TO THE OUTSIDE LINES
You may want to take time at this point to determine which outside line numbers
to assign to each Line Module jack in the control unit. The Line Module jack
can determine where a number appears on certain voice terminals.
You should plan to connect your general-purpose numbers to the first few Line
Module jacks (for example, A0, A1, ... B0, B1), reserving A0 for your published
telephone number. Fill the remaining jacks from top to bottom—lowest
telephone number first, highest one last. When you fill up one Line Module,
start at the top of the one immediately to its right. Fill the Line Modules in the
control unit before filling the ones in the expansion unit. Connect specialized
lines (for example, a WATS line) last.
NOTE: If you have basic telephones in a square system with Feature Module
1 or 2, you may not want to assign your published telephone number to jack
A0 or A1 because a basic telephone connected to a Basic Telephone Module
cannot receive calls on lines assigned to these jacks. See your administration
manual for more information on basic telephones and square systems.
