Introduction
This installation guide tells you how to install and test your MERLIN® com-
munications system, Model 206 or 410. It leads you step by step through system
installation, from a pre-installation checklist to system tests. You should per-
form 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, see the administration manual that
came with your system for programming and administration instructions. Your
system may not be fully operable until you have programmed and administered it.
This guide includes the following sections:

minals
(MERLIN system telephones) to your system.
Installing Accessories suggests some accessories you may want to con-
sider adding to your system.
System Tests provides tests to help you determine if you’ve installed your
system properly.
What’s Next? refers you to documents that explain how to customize and
use your system to meet your particular business needs.
System Changes explains how to rearrange or alter your system once it
is in place.
Troubleshooting isolates and identifies specific system problems that
could arise during 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 drawings accompanying the text. The
numbers in the drawings correspond to the step numbers in the text. The con-
trol unit most often pictured in this guide is a Model 410, but the information
presented usually applies to the Model 206 control unit as well. When there
are exceptions, both control units are pictured.

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, do so now.
●Make sure the necessary wiring is in place.
You must have a network interface that links your MERLIN system to the
local telephone company’s lines. A telephone company representative
should have installed your outside lines and labeled the network interface
to indicate the telephone number for each outside line.
You must also 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 may have
planned 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 point
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 in the Wiring Installation Kit. In either
case, you should now have building wiring that runs from the voice ter-
minal 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 one or two jack panel boxes (the “jack field”) at the control
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.
The drawing, top right, shows a direct connection between a voice terminal
and the control unit. The drawing,bottom right,shows a voice terminal con-
nected to the control unit through the building wiring.

page, and note how components are related to one another.
ing 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 locations, and make sure the control unit loca-
tion meets the following environmental standards:
—Operating temperature: 40-104°F (4-40°C)
—Humidity: not to exceed 80%
—Ventilation: Leave 6 inches of space above and to the sides of the con-
trol 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; in-
stall them side by side at least 6 inches apart.
—Airborne contamination:Do not expose the control unit to moisture, cor-
rosive gases, dust, chemicals, or similar substances.
If your control unit location does not meet these standards, your warranty may
become void.

The control unit and the cartridges it contains provide the power
and intelligence for all voice terminals and accessories.
Modular jumper cords connect the control unit to the jacks in the
jack field.
The jack field serves 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 ad-
vanced features in the control unit.
The network interface jacks provide connections to the local
telephone company lines.
Line cords connect the control unit to the network interface.
The ac outlet is the electrical power source for the control unit.
NOTE: Modular jumper cords are identical to modular voice terminal cords.
They have different names in this guide to reflect their different functions
and locations in the system.
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
Telephone numbers of the lines to which you are connecting your
system.

Installing the Control Unit
Installation procedures are basically the same for both Model 206 and Model
410. The instructions point out only those differences between the models that
affect installation.
POSITION THE CONTROL UNIT
If you plan to wall mount your control unit, follow the instructions in the booklet
titled CIB 3029 (for Model 206) or CIB 3030 (for Model 410) in your Control Unit
Installation Kit.
Whether you wall mount your control unit or place it on a table or shelf, make
sure it’s within 5 feet of an ac outlet that is not switch-controlled, within 5 feet
of the network interface, and within 6 inches of the jack field, if you have one.
The drawing, right, provides a diagram for positioning the control unit.
5 feet, maximum
6 inches, maximum
5 feet, maximum
NOTE: The ac outlet should be a 117-volt, 60-Hz, 3-prong, third-wire ground-
ed outlet. Proper grounding protects the system against damage from power
surges caused by static discharge and lightning. You should have an electri-
cian check the outlet’s third wire to make sure the outlet is properly grounded.
Power consumption for both models is 40 watts during normal operation.
SET THE CONTROL UNIT SWITCHES

Find the Tone/Pulse switch near the top of the center panel on the front
of the control unit.
If you have rotary (pulse) telephone service, set the switch toPulse
(right).
If you have Touch-Tone signal telephone service, set the switch to
Tone (left).
Find the row of switches labeled Ringing on the left panel of the con-
trol unit. Set all of them to Yes (up) for now. You may want to reset these
switches later when you customize your system.

CONNECT THE CONTROL UNIT TO THE AC OUTLET
The outlet should not be switch-controlled. Plugging your control unit into a
switch-controlled outlet invites accidental disconnection of the system.

Find the power cord attached to the control unit and plug it into the ac
outlet.
The green power light on the control unit goes on.
The red warning light next to the power light comes on momentarily and
then goes off.
If the green power light does not come on, test the outlet by plug-
ging in a radio or lamp. If the outlet is working properly, your con-
trol unit may be faulty. Contact your equipment supplier for
assistance before proceeding with the installation.
If the red warning light doesn’t blink or remains lit, unplug the power
cord and then plug it in again. If the warning light still doesn’t
operate properly, contact your equipment supplier for assistance
before proceeding with the installation.
Unless otherwise instructed, leave the power cord plugged into the ac
outlet throughout the remaining installation procedures.

PREPARE THE NETWORK INTERFACE
Your local telephone company should have installed a network interface with
1-line jacks (RJ11-type) or 2-line jacks (RJ14-type) for connecting your MERLIN
system to your outside telephone lines. The drawing, right, shows the two types
of network interface and the 2-line adapter (267C) for the 2-line network inter-
face jack. The table, below, tells you what to do depending on the type of net-
work interface you have.

TEST THE OUTSIDE LINES
This step is optional, but if you have a basic Touch-Tone or rotary telephone with
a modular plug, you should test your outside line connections now. It can save
time and frustration later.
NOTE: A MERLIN system voice terminal will not work for this test.
