Apartment Intercom Station
The Alpha Communications® IS407S (V.I.P.™ series) apart-
ment intercom stations are designed specifically to minimize
vandalism and tenant abuse. Made from .035" thick solid
stainless steel, with metal push-buttons, these stations are made
to last. A high sensitivity 2.75" (70mm) speaker assures clear
voice communication, as well as tone signal response.
The IS407S is designed to easily surface mount right onto the
finished wall surface, without a costly back box. For a more secure
installation or for uneven wall surfaces, we recommend the
optional BP407S steel backplate connector be used.
Color-coded pigtail wiring makes these stations easy to wire and
resists water corrosion found on P.C. board type stations. The
advanced electronic design permits use in any size building.
A wide variety of optional accessories is available to provide
additional functions such as multi-entrance operation, post
