Important Ordering Information

For systems requiring multiple tenant call buttons, Aiphone also offers:

These larger configurations are generally built using separately purchased DA Series components rather than the DA-1AS box set.

The electric strike, intercom cable, auxiliary devices, and other accessories are sold separately unless specifically stated.
