OR502SS Vandal-Resistant St. Steel Remote Station
The Alpha Communications® OR502SS outdoor remote intercom stations are designed specifically to minimize vandalism and abuse. Made from 16 gauge high-carbon brush finish stainless steel, with solid metal push-button, these stations are built to last. A high sensitivity 2.75" (70mm) mylar plastic cone speaker assures crisp, clear voice communication, and resists mold and mildew caused by dampness on paper cone speakers. 

The OR502SS is designed to work with many types of intercom systems, and mounts over our standard IH101 (flush) or OH700 (Black surface) or IH700G (Grey Surface) back box.

Pigtail wiring makes these stations easy to wire and resists water corrosion found on P.C. board type stations. When used with the SM201B, SM202, or SM400 series master station(s), a model EC105 non-polarized capacitor must be installed into the OR502SS remote station. Stations are also available in custom sizes and wiring configurations.
