OR502S Surface Aluminum Outdoor Remote Station

The OR502S Surface Mount Outdoor Remote Stations provide for call capability and two-way, hands-free communication to inside master stations for a variety of Alpha Communications® systems. Made of heavy duty extruded aluminum, they are designed for more rugged environments and vandal-resistant applications. The OR502S comes out of the box as a surface mount station, with no housing required. The back of the OR502S station is fully open to allow for easy wiring.

The OR502S remotes are 3-wire or 4-wire type and are normally used with systems such as the IR704B/PK724, 'EK' series music-intercoms and the IR204C/PK543 or IR204E/PK543A or IS204/IA543 or IS543/IA543 apartment entry systems. They can be converted into the 2-wire type by the addition of a model EC105 nonpolarized capacitor, for use with systems such as the SM201B, SM401, SM401TS, SM404, SM404TSSM406, and SM411 (and others).
