Intercom Solutions

The Nortek Security & Control Family of Brands

Say “intercom”, and most people think of “tinny” sound and inconsistent performance…

Those days are long gone!

Today, Nortek Security & Control’s communication and whole-house music distribution systems deliver true sound for
music and voice. These elegant and sophisticated acoustical systems deliver quality sound throughout the home. They also
ensure peace of mind with enhanced security and room monitoring features.

For more than 50 years, a company named M&S Systems has been the leading designer and manufacturer of fine systems
for home communication and entertainment. These products revolutionized home communications with technology, style, and
value. That company is now part of Nortek Security & Control, where the legacy of quality in design and development
continues on.

Systems for new installation using Cat-5 wire

Nortek Security & Control’s DMC1 Music/Communications System offers much more than just good looks. Designed for
today’s home, the DMC1 offers the homeowner the ability to communicate and monitor up to 15 rooms and up to three door
speakers. The add-on model DMCBT offers music playback and adds wireless streaming capability from smartphones, tablets,
and other Bluetooth-enabled music/audio streaming products.

Systems for 3-wire, 4-wire, and 6-wire retrofit installations

Nortek Security & Control’s DMC3-4 offers many of the same features as the DMC1, but it is engineered to run on
existing wires. The DMC3-4 will replace most older 3-wire or 4-wire M&S Systems and NuTone intercoms (use DMC1 for
6-wire retrofits). Unique retrofit finish-out frames make installation easy by eliminating the need to repair drywall.
The DMC3-4 retrofit also offers an optional Bluetooth® Player.
