OR501/2 Aluminum Outdoor Remote Stations

The Alpha Communications® OR501/2 outdoor remote stations are a low-cost alternative for a 2 button apartment house entry intercom panel. They are our lowest cost 2-button entry panels. Since there are no nameholders, directories or button markings, and due to its small size, the OR501/2 is a real cost saver. Made of heavy duty extruded aluminum, they are designed to look good and to last. 

The OR501/2 stations are normally used with our IA543 or PK543A amplifier, for apartment entry intercom applications.
