Provide simple, reliable visitor communication and remote door-release capability with the Aiphone C-123 ChimeCom Intercom System.

Designed for residential, office, retail, and light-commercial entrances, the C-123 Series provides a distinctive chime when a visitor presses the door-station button. Personnel can then communicate with the visitor using the interior C-ML/A master station and activate a compatible electric door release directly from the master.

Choose the C-123L/A for a single-master installation or the C-123LW when two interior master stations are required.
