The AS-3A Wall/Desk Mountable Single Call Sub Station from Aiphone features a push button. The sub station calls the master station, and activates tone and LED that remain activated for 20 seconds after the call button is released. This sub station can be used with the MP-3S and AP-5M/10M Intercom Systems only. Communication is hands-free when the master station answers. It can be wall mounted to a standard 1-gang box or desk mounted to a ring (mounting hardware not included).
