Audio Only Intercom

The stalwart of the Aiphone line, this audio only, selective calling, open-voice audio intercom system has the capacity of up to 11 total stations. For basic communication to door stations and between inside master stations along with activating a door release unit, this bare-bones, legacy system can be designed to meet a wide variety of needs.

Freakishly Reliable

Aiphone is proud to be a rare, two-time winner of the prestigious Deming Prize for quality management and manufacturing processes.  Our ISO Certified process and rigorous standards result in some of the most reliable products in the industry. Aiphone products routinely last for years, only being replaced when the application outgrows the system capacity.
