Figure 1. Required Parts

You will need to obtain four #12 screws of the appropriate type for the wall and weight of the control unit (a control unit with four 206 modules and a processor module weighs approximately 27.5 pounds or 12.3 kilograms).

In addition, if you need modular telephone cords for connecting the extension jacks on the control unit to the modular connecting blocks for extensions in the equipment room, short telephone cords for wall mounting MLS-model phones, or a 355A/355AF adapter and D8W telephone cord for connecting a call reporting device, order them before installation. Refer to “Product Ordering Information” in Appendix B of the PARTNER Plus Communications System Programming and Use guide for ordering instructions.

NOTE:

Asystem display phone—either an MLS-34D, MLS-18D, or MLS-12D—is required for system programming at extension 10 and/or 11. (Make sure that the programming phone is as large as the largest phone in the system, because an MLS-12D or MLS-18D cannot program an MLS-34D. Similarly, an MLS-12D cannot program an MLS-18D.)
