General Information

Outdoor Remote Station with Momentary Metal Call button. Stainless Steel Finish. Can be Flush or Surface Mounted with the appropriate back box/housing.
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 (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, SM203B, SM205 (series), SM210 (series) or SM401, SM404, SM406 or SM411 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.
