Introduction
Even the magic of the MERLIN™ communications system sometimes fails. The problem
may be a user error, installation problem, or faulty component. Usually you can correct the
problem on the spot without returning any equipment for maintenance exchange.
The Service and Maintenance Manual: Models 206, 410, and 820 is intended for use by both
the customer and the service technicians. This troubleshooting manual is divided into four
parts:
Functional Overview describes each communications system component and its use.
●
●
Isolating and Correcting Troubles includes step-by-step procedures to help you isolate a
problem to a user error or a specific component. Most procedures require no tools. A few
procedures require a screwdriver or a basic Touch-Tone or rotary telephone (a Power
Failure Transfer Telephone will work).
●
CIBs includes copies of customer instruction booklets shipped with the components. The
CIBs describe the functional features and installation of each component.
●
Index lists problems, features, and components. It will help you find the information you
need quickly.

Functional Overview
This section describes the components of the MERLIN communications system and explains
how they fit together in a typical installation. Normally, MERLIN system installations will
include most of the major components shown on page 4.
Additional equipment may be attached to the MERLIN system to provide expanded features
and services. See pages 15 to 19 for information about optional voice terminal accessories
and control unit accessories.
Further information on many of the components (including installation instructions) is available
in the customer instruction booklets (CIBs) included under the CIB tab divider. The CIB
number for each component appears near its illustration. When more than one CIB is listed,
the appropriate title also appears.

MAJOR SYSTEM COMPONENTS
1.
Control unit: The control unit is the heart of the MERLIN system. It provides the
power and intelligence for all voice terminals as well as the connection between voice
terminals and outside lines. Program memory for the MERLIN system resides in the
control unit. The model number of the control unit determines its capacity:
●
Model 206 control unit has a capacity of 2 outside lines and 6 voice terminals.
●
Model 410 control unit has a capacity of 4 outside lines and 10 voice terminals.
●
Model 820 control unit has a capacity of 8 outside lines and 20 voice terminals.

System Overview
2.3.Network interface: The network interface connects the control unit and the outside
lines. The two most common network interfaces are the one-line (RJ11) and two-line
(RJ14) interfaces. However, other network interfaces may be used (see the InstallationGuide: Models 206 and 410 and the Installation Guide: Model 820).
Jack field: The jack field provides the connections between the control unit and the
wiring to the voice terminals. The jack field may consist of either jack panel boxes or
modular jacks mounted near the control unit. (However, in some systems, the voice
terminals plug directly into the control unit using modular voice terminal cords and
extension cords.) Optional attachments (extra alerts, paging systems, etc.) may also
connect to the control unit through the jack field.
4
4.
Modular jack: Each voice terminal wiring run from the jack field terminates in a modular
jack at the voice terminal location. Every voice terminal has a separate modular jack.
5.
Voice terminal (MERLIN system telephone): The voice terminal provides basic
telephone functions as well as access to the advanced feature software residing in the
control unit.
MERLIN system voice terminals may be installed in a near-by building by using
Outdoor Wiring Protection Units. Contact your equipment supplier for more information.
Basic Touch-Tone and rotary telephones may also be used as off-premises telephones
with the MERLIN system using the optional Off-Premises Telephone Interface to
connect them. In that case, off-premises telephones access system features by means
of dial codes.
The following pages describe in detail the control units (by model), optional cartridges and
line/voice terminal modules, voice terminals, and accessories.
5
CONTROL UNIT
The control unit provides power for most voice terminals and accessories. All outside lines
and all voice terminals and telephones connect to the control unit, which contains the
microprocessor and memory for all the advanced features available with the MERLIN
communications system.
NOTE: Page 7 explains in greater detail the physical features of the Models 206 and 410
control units. Since they are the same except for the number of outside line jacks and the
number of voice terminal jacks (Model 206 control unit has 2 outside line jacks and 6 voice
terminal jacks; Model 410 has 4 outside line jacks and 10 voice terminal jacks), only
Model 410 is pictured on page 7.

TYPE I CARTRIDGES: FEATURE PACKAGES
A Type I cartridge occupies the top slot on the right side of the control unit. This cartridge
contains all the programming for the custom features of the MERLIN system. (Without this
cartridge, the system has standard features only.) The individual voice terminal has no
memory or programming capabilities itself. A voice terminal, when connected to the MERLIN
system, can be programmed to perform specific functions. However, the actual program
instructions are stored in the cartridge, not in the voice terminal. The cartridge may come with
a label that fits over the standard features or Ringing switches label. For example, Feature
Package 1 (Models 206 and 410 only) comes with the label Outward Calls.
For more specific information regarding the features provided by Type I cartridges, refer to the
administration manuals and user’s guides for Models 206, 410, and 820 that accompany the
cartridges.

Auxiliary Power Unit (Model 820 only)
The Auxiliary Power Unit connects to the Model 820 control unit to provide the extra power
necessary in systems with many accessories or 34-button deluxe voice terminals. Follow
these steps to see if the system requires an Auxiliary Power Unit.
1.
Count how many voice terminals are connected to the control unit. Do not count 34button deluxe voice terminals or voice terminals that have a Voice Terminal Power
supply.
2.
Count how many accessories (such as Hands-Free Units) and 34-button deluxe voice
terminals are connected to the control unit and add the two numbers together. Do not
count voice terminals that have a Voice Terminal Power Supply.
3.
Add numbers from steps 1 and 2. If the total exceeds 28, an Auxiliary Power Unit is
recommended. If the problem occurs only at 34-button deluxe voice terminals, adding
Voice Terminal Power Supplies at those voice terminals instead of an Auxiliary Power
Unit is recommended.

TROUBLE ON ONE TELEPHONE
Ringing
Symptom:
A line rings but no caller is on the line. (The user attempts to answer a call but
loses it and receives dial tone on a different line.)
Possible Cause
User rocked the handset while lifting
it.
Recommended Action
Rocking the handset causes the voice terminal to
go off hook, on hook, then off hook again. Instruct
the user to lift the handset without rocking it to
either side.
Symptom:
10-button voice terminals exhibit peculiar ringing and/or extra lights are lit.
Possible Cause
A brief ac power outage occurred.
Recommended Action
A brief ac power outage causes certain early
production 10-button voice terminals to exhibit
peculiar ringing. Extra lights also may be on.
Momentarily removing ac power from the voice
terminal corrects the problem. Do this by
unplugging the voice terminal cord at the modular
jack and plugging it in again.

Follow these steps to see if the system requires an
Auxiliary Power Unit:
1.
Count how many voice terminals are
connected to the control unit. Do not count
34-button deluxe voice terminals or voice
terminals that have a Voice Terminal Power
Supply.
Count how many accessories (such as Hands-
2.
Free Units) and 34-button deluxe voice
terminals are connected to the control unit and
add the two numbers together. Do not count
voice terminals that have a Voice Terminal
Power Supply.
Add the numbers from steps 1 and 2. If the
3.
total exceeds 28, an Auxiliary Power Unit is
recommended. If the problem occurs only at
34-button deluxe voice terminals, adding Voice
Terminal Power Supplies at those voice
terminals instead of an Auxiliary Power Unit is
recommended.
