St. Steel Remote Station
The Alpha Communications® OR502SS outdoor remote inter-
com 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.
