  • Page 4: Introduction

    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.

  • Page 6: Functional Overview

    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.
  • Page 7 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.
  • Page 8 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. 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.

  • Page 9: Control Unit

    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.
  • Page 10 Physical Features of the Model 206 and 410 Control Units (Model 410 is pictured) Voice Terminals jacks: Jacks labeled 0 through 5 (Model 206) or 10 through 19 (Model 410) accommodate MERLIN system voice terminals. Warning light (red): Comes on momentarily when the ac power cord is first plugged in. If the warning light remains on, it can also indicate trouble.
  • Page 11 Model 820 Control Unit Behind the removable front panel of the Model 820 control unit is one line/voice terminal module that accommodates 2 outside lines and 5 voice terminals. The Model 820 control unit can accommodate up to four line/voice terminal modules for a maximum of 8 outside line jacks and 20 voice terminal jacks (for more information on available types of modules, see page 12).
  • Page 12 Tel. Co. Lines jacks: Jacks labeled A and B on the 2-Line/5-Voice Terminal Module shipped with the control unit provide connections for outside lines. Voice Terminals jacks: Jacks labeled 10 through 14 on the 2-Line/5-Voice Terminal Module shipped with the control unit provide connections for MERLIN system voice terminals.
  • Page 13 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.
  • Page 14 TYPE II CARTRIDGES: AUDIO OPTIONS A Type II cartridge provides connections for such features as Loudspeaker Paging, Background Music, and Music-on-Hold. It is installed in the second slot on the right side of the control unit. Pictured below is the Music-on-Hold/Paging Cartridge. A Music-on-Hold Type II cartridge with only the Music-on-Hold feature is also available;...
  • Page 15 TYPE III CARTRIDGES: LINE-ASSOCIATED OPTIONS A Type III cartridge provides line-associated options. It is installed in the third or last slot on the right side of the control unit. Pictured below is the Extra Alert/2-Line Power Transfer Type III cartridge. Power Fail Lines jacks: Connect two basic Touch-Tone or rotary telephones for automatic backup...
  • Page 16 OFF-PREMISES TELEPHONE INTERFACE TYPE C (Optional) The Off-Premises Telephone Interface is optional. This unit connects off-premises telephones to the MERLIN communications system, making the advanced features available to the off- premises user. The unit can be mounted on the wall or placed near the control unit. Power is supplied directly through the voice terminal module jack connection described below.
  • Page 17 VOICE TERMINALS Several types of voice terminals may be connected to Models 206, 410, and 820. They are distinguished from one another by the number of silver membrane buttons above and to the right of the dial pad. These buttons give access to lines and features; most buttons are programmable.
  • Page 18 OPTIONAL EQUIPMENT In addition to the essential components of the MERLIN communications system, several different accessories may be connected to voice terminals or the control unit. Optional Voice Terminal Accessories Hands-Free Units, Headset Adapters, and Manual Multipurpose Adapters can be connected directly to the underside of the voice terminal as illustrated below.
  • Page 19 Headset Adapter The Headset Adapter makes it possible to use a headset with a 10-button or 34-button voice terminal. Headset light: Goes on when headset is in use. On/Quiet switch: Turns adapter sound on; when held down, provides “mute” function. Off switch: Turns adapter sound off.
  • Page 20 Manual Multipurpose Adapter The Manual Multipurpose Adapter (illustrated below) permits these devices to be connected to a voice terminal: Modems and data terminals with built-in modems. (An extra telephone is not needed with an AT&T 212A-type modem with a special cable. Automatic answering modems cannot be used.) Basic Touch-Tone or rotary telephones.
  • Page 21 Control Unit Accessories Some optional accessories connect directly to the control unit to give the MERLIN system additional capabilities. Extra Alerts Extra alerts such as horns and bells provide signaling in large, open areas (for example, warehouses and parking lots) and especially noisy environments. Extra alerts connect either directly to the Services Module on the control unit or by the Extra Alert Switch.
  • Page 22 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. Count how many voice terminals are connected to the control unit.
