AIPHONE IEH-1CD room sub station

The Aiphone IEH-1CD Chime Tone intercom system sub-master handset enables a door intercom system to extend its call answering capabilities into multiple rooms or over a large area. Visitor calls activate a chime and LED indicator in both the master and sub-master handsets and can be transferred between handsets. The door release button works with an electric strike (sold separately) to remotely unlock the entrance for the visitor. The sub-master handset can send and receive calls from the master handset for internal communication.

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.
