NIM Series


Lamp Tone Intercom

The NIM Series is a Lamp Tone Intercom supporting a single master station and up to forty sub stations. Calls to the sub stations can be placed selectively or via All Call from the master station. Calls from a sub station will sound at the master and activate a light, displaying the location of the call.

Freakishly Reliable

Aiphone is proud to be a rare, two-time winner of the prestigious Deming Prize for quality management and manufacturing processes.
