Aiphone C-ML/A ChimeCom Master Intercom with Door Release Button

The Aiphone C-123ML/A ChimeCom single-door master intercom works with an Aiphone C-D door intercom (sold separately) to enable audio communication with visitors prior to authorizing access to the building using the door release button. The master intercom has both a push-to-talk button and a pull cord that can be used to initiate audio transmission to the door intercom. Once the cord or button is released, sound from the door intercom is transmitted immediately to the master intercom, automatically shutting off after 20 seconds. The door-release button works with an electric strike (sold separately) to remotely unlock the entrance for the visitor.

At any time, the push-to-talk button can be pressed or the chain pulled to listen through the door intercom. Housing is white plastic, and the audio volume is adjustable. The system is hardwired to be powered by a 6V power supply (sold separately) but can be powered by four C batteries (sold separately) to facilitate installation where power outlets are not accessible.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Door intercom systems allow an occupant of a building to communicate remotely with a visitor through at least one door intercom and master intercom. Master intercoms with a door-access button remotely unlock the door for the visitor.

Aiphone manufactures intercom systems for residential, business, and healthcare structures. The company, founded in Japan in 1948, has its North American headquarters in Bellevue, WA. Aiphone meets International Organization for Standardization (ISO) standards 9001 and 14001.
