Product Description

 

The Alpha Communications SM222K (Duo-Com) intercom kit is our most economical master/remote intercom for door entry or any other application requiring a single master and a single remote intercom station, with expand-ability for a 2nd master station.

The SM222 master station has a built-in amplifier and electronic chime. It easily mounts right on the surface of the wall and can directly replace an existing door chime or door bell, on the existing 2- wires! A built-in momentary door release button allows hookup to your own low voltage door opener (depending upon transformer used). The compact OR222 outdoor remote station is fully enclosed with a built-in rainhood. It surface mounts directly on the wall, and requires only 2 wires.

The optional PK407A door opener relay allows connection to mag locks or other types of door openers.

The SM222 master stations can be desk mounted using the optional model IH400A desk cabinet.
