Installation Guidelines

Telephones and Devices

You can connect the following telephones and devices to the system:

■MLS- and MLC-Model System Phones. System phones require at least two-pair wiring and are compatible with AT&T 4-pair SYSTIMAX™ wiring.

■Call Assistant Intercom Autodialers with Busy Indication

(MLS-CA24).You can connect an Intercom Autodialer to the system phone at extensions 10 and 11 (maximum two per system). The Intercom Autodialer has its own power supply, which must be plugged into an AC outlet.

■Industry-Standard Devices. Industry-standard devices (including standard phones) require one-pair mounting cords; AT&T D2R mounting cords are recommended.

—Standard Phones. Connect standard touch-tone or rotary dial phones to the system for:

—Power Failure Operation. During a power failure, system phones will not work because they require power to operate. However, if you connect standard phones to extensions 10, 16, 22, and 28, users can place and answer outside calls on lines 1, 3, 5, and 7, respectively. You can connect a standard phone either alone or combined with a system phone. (If you combine a standard phone and a system phone on one extension, you may want to turn off the standard phone’s ringer during normal use.)

—Hotlines. A hotline extension should be connected to a standard phone, rather than a system telephone, but can ring any type of phone. A hotline phone can also be set up to ring the paging system, so announcements can be made over the loudspeaker. Do not connect a Hotline phone to extension 10, 16, 22, or 28, to keep them available for power failure use.

—Auxiliary Equipment. There are a variety of ways to set up fax machines, modems, and answering machines to work with the system. See Chapter 4 in the PARTNER Plus Communications System Programming and Use guide for advice on using this equipment. To connect a telephone and a standard device on the same extension, see “Combination Extensions” on page 6.

■Doorphones. You can connect up to two doorphones to the system. Do not connect doorphones to extension 10, 11, 16, 17, 22, 23, 28, or 29.

■Call Reporting Devices. You can connect a call reporting device to the SMDR jack on the processor module for recording call activity.

■In-Range Out-of-Building Protectors. Installing phones in a different building from the control unit requires AT&T In-RangeOut-of-Building (IROB) protectors, to prevent damage due to lightning. (IROBS must be installed by a qualified technician.)
