Introduction

Even the magic of the MERLIN™ communications system sometimes fails. The problemmay be a user error, installation problem, or faulty component. Usually you can correct theproblem 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 boththe customer and the service technicians. This troubleshooting manual is divided into fourparts:

●

Functional Overview describes each communications system component and its use.

Isolating and Correcting Troubles includes step-by-step procedures to help you isolate aproblem to a user error or a specific component. Most procedures require no tools. A fewprocedures require a screwdriver or a basic Touch-Tone or rotary telephone (a PowerFailure Transfer Telephone will work).

CIBs includes copies of customer instruction booklets shipped with the components. TheCIBs describe the functional features and installation of each component.

Index lists problems, features, and components. It will help you find the information youneed quickly.

Functional Overview

This section describes the components of the MERLIN communications system and explainshow they fit together in a typical installation. Normally, MERLIN system installations willinclude most of the major components shown on page 4.

Additional equipment may be attached to the MERLIN system to provide expanded featuresand services. See pages 15 to 19 for information about optional voice terminal accessoriesand control unit accessories.

Further information on many of the components (including installation instructions) is availablein the customer instruction booklets (CIBs) included under the CIB tab divider. The CIBnumber for each component appears near its illustration. When more than one CIB is listed,the appropriate title also appears.

MAJOR SYSTEM COMPONENTS1. 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 voiceterminals and outside lines. Program memory for the MERLIN system resides in thecontrol 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.

Network interface: The network interface connects the control unit and the outsidelines. 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 thewiring to the voice terminals. The jack field may consist of either jack panel boxes ormodular jacks mounted near the control unit. (However, in some systems, the voiceterminals plug directly into the control unit using modular voice terminal cords andextension cords.) Optional attachments (extra alerts, paging systems, etc.) may alsoconnect to the control unit through the jack field.

5.

Modular jack: Each voice terminal wiring run from the jack field terminates in a modularjack at the voice terminal location. Every voice terminal has a separate modular jack.

Voice terminal (MERLIN system telephone): The voice terminal provides basictelephone functions as well as access to the advanced feature software residing in thecontrol unit.

MERLIN system voice terminals may be installed in a near-by building by usingOutdoor Wiring Protection Units. Contact your equipment supplier for more information.

Basic Touch-Tone and rotary telephones may also be used as off-premises telephoneswith the MERLIN system using the optional Off-Premises Telephone Interface toconnect them. In that case, off-premises telephones access system features by meansof dial codes.

The following pages describe in detail the control units (by model), optional cartridges andline/voice terminal modules, voice terminals, and accessories.

Note: This section explains how toconnect your music source tothe 150A Cartridge by runningeither 18- or 24-gauge wirefrom the 8-ohm input of themusic source to the “M1” and“M2” terminals on the car-tridge.

Warning: Unplug the power cords ofthe control unit and themusic source from the acoutlet before making anyconnections to the car-tridge.

Wrap the end of one wire around an8-ohm output terminal screw on yourmusic source. Take the same end of asecond wire and wrap it around theother terminal screw associated withthe 8-ohm output on your musicsource. Tighten the screws.

Note 1:

Note 2:

The music source should betested with speakers beforemaking the connections tothe music on hold. The acpower should be discon-nected from the musicsource before making anyconnections.

The same 8-ohm output can-not be connected to aspeaker and the music-on-hold cartridge. Since theamplitude required to drivea speaker is much greaterthan the music-on-hold inputwill accept, it causes themusic on hold to be dis-torted.

Loosen but do not remove the twoterminal screws marked M1 and M2.

Take each wire from the output of themusic source and loop it clockwisearound a terminal screw (Figure 4).Again, it is not critical which wire goesto “M1” and which goes to “M2”.

●

user-provided 2-watt, 8-ohm mu-sic source, it provides music tooutside callers who are placed onHOLD.

When properly connected to aloudspeaker paging system, it per-mits users to make paging an-nouncements over the loud-speaker from their voice termi-nals.

It can also provide backgroundmusic over the loudspeaker pag-ing system.

Figure 1

“T” and “R” Terminals

The “T” and “R” terminals on the car-tridge connect to the “telephone” input onyour paging system. The connection allowsyou to access the paging system via the in-tercom from any voice terminal. The “T”and “R” terminals are a 600-ohm, dry bal-anced output; therefore, it is not criticalwhich of the two terminals on the pagingunit is connected to “T” and which is con-nected to “R” (dc-offset voltage is as-sumed to be 0 volts).

Paging Signal Switch

The “Paging Signal” switch provides thefollowing options:

ON: When switched to the “ON”position, all paging announce-ments are preceded by a tone.

1.

2.

OFF: No tone precedes the pag-ing announcement over the loud-speakers.

Control Terminals

The “1” and “2” terminals on the car-tridge can be used for signaling the pagingsystem when a page is in progress (for ex-ample, to turn off background music). The“1” and “2” terminals are switched con-tacts that are normally open but becomeclosed when a page is initiated. A maximumof 40 volts, 0.25 amperes can be appliedacross the terminals.

Background Music Volume Con-trol

This control is used to adjust the volume ofyour background music. Turning the screwclockwise increases the volume, turning itcounterclockwise decreases the volume.

Note: You may also have volumecontrols on your speakers andpaging system.

Music Terminals

These terminals when properly connectedto a music source, allow you to have musicon hold, and if desired, background musicon your paging system. “M1” and “M2”are a dry balanced 8-ohm input; therefore,it is not critical which terminal on the mu-sic source is connected to “M1” and whichis connected to “M2” (the dc-offset is as-sumed to be 0 volts). A maximum of 0.3volts peak to peak can be applied acrossthese terminals before the signal is dis-torted. Protection is provided for larger sig-nals.

Music-on-Hold Volume Control

This control is used to adjust the volume ofyour music on hold. Turning the screwclockwise increases the volume and turningit counterclockwise decreases the volume.
