Installation & Configuration Manual 

 

The Alpha Communications® IA543 Intercom Amplifier is designed to allow two-way communications between 
an open voice lobby panel and multiple apartments. Additional equipment will allow communications with 
multiple entrance panels. Entrance panels will signal up to an apartment by pressing the corresponding call 
button, and the resident can answer using

buttons. A  

DOOR

 button provided on the 

apartment station can be configured to operate an electric door strike or magnetic lock to allow visitor entry. 

 

The IA543 is compatible with additional equipment to provide specialized applications and features such as 
hearing impaired strobe lights, multiple sequenced door operations, integration into access control systems, 
and Postal locks.
