Entry Intercom Station
The Alpha Communications® OR502/1NYH (V.I.P.™ series)
entry 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 sta-

The OR502/1NYH is designed specifically to meet the needs of
New York City Housing Authority projects, and mounts onto
the IH101 (flush) or IH700G (surface) back box.
Pigtail wiring makes these stations easy to wire and resists water
corrosion found on P.C. boar
