Any of the following voice terminal models will work at any voice terminal location directly connected to your MERLIN Plus system:

5-Button voice terminal

BIS-10 voice terminal

10-Button voice terminal

10-Button voice terminal with Hands Free Answer on Intercom (HFAI)

BIS-22 voice terminal

BIS-34 voice terminal

BIS-34D voice terminal

34-Button (SP-34) voice terminal with speakerphone

34-Button (SP-34) voice terminal with speakerphone and display

34-Button deluxe voice terminal

34-Button voice terminal

Assign voice terminals to the locations based on the requirements of your system and the needs of individual users. For example, an attendant/receptionist at the intercom 10 location will require one of the 34- button voice terminals or a BIS-22 voice terminal. For more information on voice terminals and preparing them for the system connection, see "Step 3: Connecting the Voice Terminals" under "Prepare the Voice Terminals."

Make sure the control unit power is off before plugging and unplugging modular cords into the control unit. This prevents you from darnaging the voice terminal module if you accidentally pull on a cord that is attached to it. When the power is off, follow these steps to connect each voice terminal to the system:

1 Place the voice terminal in its designated location.

2 Plug the voice terminal into the system.

If each connection only requires one modular cord, test the connection as described in "Testing Each Voice Terminal," in "Step 3: Connecting the Voice Terminals."

If each connection requires one or more extension cords, plug the loose end of the voice terminal’s modular cord into the jack on the extension cord that terminates the wiring run to the control unit. Then go back to "Testing Each Voice Terminal" in "Step 3: Connecting the Voice Terminals."

Moving voice terminals directly connected to the control unit

To move a telephone with a direct connection to the control unit, do the following:

1Find the modular cord that terminates the wiring run from the new location to the control unit.

2Go to the control unit and locate the jack with the voice terminal’s intercom number.

3Turn the control unit off.

4If another cord is in the jack with the voice terminal’s new location number, unplug it. (Place it aside until you have use for it.)
