Introduction This installation guide tells you how to install and test your MERLIN ® communications system, Model 206 or 410. It leads you step by step through system installation, from a pre-installation checklist to system tests. You should perform the steps in the order in which they are presented because many of the earlier steps prepare the system for later steps.
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.
● ● Check the items in your shipment against your copy of the order form. Make sure the items and quantities agree. Save the instructions packed with components; you may need to refer to them later. And keep the packing 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.

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.
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. 1 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 plugging in a radio or lamp.
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 interface jack. The table, below, tells you what to do depending on the type of network 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. 1 Take a basic Touch-Tone or rotary telephone with a modular plug to the network interface. 2 Plug the telephone’s modular line cord into each outside line jack, and listen for a dial tone.
CONNECT THE CONTROL UNIT TO THE NETWORK INTERFACE When you are assigning outside lines to the outside line jacks on the control unit, keep in mind that the MERLIN system automatically selects lines in alphabetical order for your outgoing calls unless you have a Feature Package and have programmed a different line-selection sequence. Let’s say, for example, that you have a Model 206 with two outside lines.

Voice Terminal Wiring The intercom number for each voice terminal in your MERLIN system is the same as the number of the voice terminal jack on the control unit to which that voice terminal is connected. On a Model 206 control unit, the voice terminal jacks are numbered 0 through 5. On a Model 410 control unit, the voice terminal jacks are numbered 10 through 19.

DIRECT CONNECTION 1 To connect your voice terminal locations directly to the control unit, do this: 1 In the system directory, fill in the voice terminal location you have selected for each intercom number. 2 Beginning with the pair of labels marked 0 for Model 206 or 10 for Model 410, label each cord at both ends with matching labels. TIP: If the distance between a voice terminal location and the control unit requires the use of extension cords, label each end of the wiring run.
Connecting the Voice Terminals Each voice terminal has the following components: ● Voice terminal body ● Handset ● Coiled handset cord ● Modular voice terminal cord ● Desk stand and/or wall mount PREPARE THE VOICE TERMINALS Voice terminal 3 LINE Handset Prepare the voice terminals as follows: 1 Assemble each voice terminal and attach the desk stand or wall mount following the instructions that come with the components.
CONNECT EACH VOICE TERMINAL TO THE SYSTEM 1 Place the voice terminal in its designated location. 1 2 Plug the voice terminal into the system in one of the following ways: If You Have a direct connection from the voice terminal to the control unit a jack field connection to the control unit And the connection requires only a single modular voice terminal cord Go on to step 3. You have already connected the voice terminal to the system in step 3 of “Prepare the Voice Terminals,” page 15.
3 Slide the T/P switch to T and hold it there. All the red and green lights on the voice terminal begin to flash, and a tone sounds. If the lights do not flash: Do This A. Check the green power light on the control unit. B. Check the wiring run from the control unit to the voice terminal. If Then the green power light is on go to B. the green power light is off unplug the power cord from the ac outlet and plug it in again.
TEST EACH VOICE TERMINAL FOR A DIAL TONE 1 Lift the handset. The green light goes on next to the shining red light, and you hear a dial tone. 2 Press one or more of the dial pad buttons. 1 The dial tone stops. If your system does not respond as described, make a note of it and refer to the Troubleshooting Table, page 26, after you’ve completed the installation. 2 ATTACH AND VERIFY THE INTERCOM NUMBERS 1 Fill in an intercom number label for each voice terminal.
Installing Accessories Once you have installed your MERLIN system, you may want to add accessories to enhance your system’s capabilities. CARTRIDGES Cartridges provide the software and interfaces that make it possible for you to use many of the MERLIN system features and accessories. Without any cartridges, you will have Standard Features, which include Automatic Line Selection, Push-Button Dialing, Hold, and Intercom.
OTHER ACCESSORIES You can enhance your system by adding accessory equipment. Accessories such as Extra Alert horns, Loudspeaker Paging, and Power Failure Transfer telephones require additional cartridges. General Purpose Adapters for your voice terminals allow you to connect modems, autodialers, cordless phones, and other extension phones. You can also connect headsets and Hands-Free Units to your voice terminals.
System Tests Now that your system equipment is in place, you need to test it to make sure it’s operating properly. The following tests will help you determine if you have installed your system correctly and if all your system components are working. If these tests reveal any problems, see the Troubleshooting Table, page 26. 1 PLACE AN OUTSIDE CALL Using any voice terminal in your system: 1 Lift the handset. The green light goes on next to the shining red light.
PLACE AN INTERCOM CALL Make this test call from one voice terminal to another voice terminal in your system. Have someone available to answer the intercom call. 1 From a voice terminal, touch the fifth button down in the leftmost row of buttons (Intercom-Ring) without lifting the handset. The red light next to the button goes on. 2 Lift the handset. The green light next to the button goes on. 3 Dial your partner’s intercom number. You hear intermittent ringing.
What’s Next? Now that your MERLIN system is installed, you need to program it to meet your business needs. If you have standard features, refer to the Standard Features User’s Guide: Models 206, 410 and 820. If you have a Feature Package, refer to the administration manual that comes with the Feature Package to learn how to customize the system to meet your business needs. Then, review the user’s guide that also comes with the Feature Package to learn how to use the MERLIN system custom features.
System Changes Your MERLIN communications system is designed so that you can make system changes quickly and easily. You can increase your system’s capacity simply by adding outside lines and voice terminals to a maximum of 2 lines and 6 voice terminals for Model 206, and 4 lines and 10 voice terminals for Model 410. You can increase the system’s capabilities by adding cartridges and accessories.
UPGRADING FROM MODEL 206 TO MODEL 410 If your needs expand beyond the capacity of your Model 206 system, you can easily install a Model 410 system in its place. You can reuse the cartridges, voice terminals and accessories that came with your Model 206. 1 Have your local telephone company add outside line(s) and network interface jack(s) to those you already have.
