IS407S Vandal-Resistant Apartment Intercom Station

The Alpha Communications® IS407S (V.I.P.™ series) apartment 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 included 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 office door release, silent or delayed door release, etc. Stations are also available in custom sizes and wiring configurations.
