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 Installation Guide: 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.

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.
