The door intercom can be connected to preexisting doorbell wiring for simple installation. The door intercom has a call button that is backlit for visibility and activates a muted chime on the door intercom itself as well as a two-tone chime on the white plastic master intercom to alert the master intercom operator. The master intercom has a push-to-talk button that receives audio from the door intercom once released. The audio transmission times out after 15 seconds. At any time, the push-to-talk button can be pressed to listen through the door intercom. Both the chime and the audio volume have adjustable sound levels. Housing is white plastic for the master intercom and gray plastic for the door intercom. A second master intercom (sold separately) can be added for large areas or multiple rooms.
