Most homes are equipped with an intercom system which enables the homeowner to have whole house music and two way communication from one room station to the other. This system is also connected to a door bell which conveniently enables two way conversations from any room station in the home. E.Security Alarm Systems has partnered with Linear, M&S who manufactured the award winning DMC1 and DMC 3-4 retrofit system. The DMC1 is equipped to operate using category 5 cables and is primarily installed under a new construction environment. Most businesses installed the DMC1 such as in a doctors or dentist office for serene relaxing music throughout. In the event a two-way conversation or an announcement is needed, that can easily be accomplished from any room station in the office. In a residential environment, the same benefits exist however the system is connected to a door bell and visitors can be screen from any room station.

M&S Systems and Linear Technologies have out done the competition by inventing the iDMC1ndustry first retro-fit-able and adaptable intercom systems called the DMC 3-4.  The Model dmc3-4 Music/Communication Retrofit System Master (White) is a full-function intercom and music distribution system designed for retrofit applications in residential use. The master unit can replace older intercom systems that use three-wire or four-wire connections to the room stations. The system supports up to 15 room stations and up to three door speakers. The built-in AM/FM radio tuner allows setting eight AM station presets and eight FM station presets. The backlit liquid crystal display shows the operation mode, audio source, radio frequency, volume setting, and time. With the optional Model dmc1CD Add-on 6-disc CD changer installed, the display shows the disc number selected and the track number currently playing.

Room stations have pushbuttons that control the system operation. Retrofit roomesecurity-mu-dmc34-diagram and patio stations connect to the master unit using the installation’s existing wiring. All room station models can select talk or listen to other room stations, door speakers and the master unit. Each has an intercom volume control. The Model dmc3RS or dmc4rs room stations and dmc3RW or dmc4RW patio stations can select the audio source, control the radio tuner, and set the master music volume.
With the addition of the optional Model MC960PA Remote Power Amplifier, stereo music can be distributed from the master unit through up to 30 pairs of in-ceiling or in-wall speakers. For access control, the optional Model DRW Door Release Mechanism can be installed and activated from the master unit or room stations.
