Intercom System – 142

Intercom System - 142

General Information

2-Wire Switchboard Intercom using remote handset type stations. Ideal for apartment houses, bowling alleys, elevators, motels, supermarkets and other applications.
The Alpha Communications /Elvox 142 series intercom system is an internal intercom switchboard system that can be used in Luxury Apartment Buildings, Dormitories, Health Care Facilities, Hotels, Motels, Schools, Offices, Bowling Alleys and Supermarkets. The 142 series is an advanced system, with individual lamp annunciation, conversation privacy, and large remote handset capacity. Models above 60 stations incorporate a \’station multiplier\’ feature that allows the amount of station selector switches to be reduced by half. This feature greatly reduces the overall size of the master station, for larger systems. Up to 120 (or more) remote handsets can be used and all handsets can call to the switchboard (or be called from the switchboard), with full communication privacy. Model 870W and model 902 handsets are two-tone White/Black and model HT2009/2WH is All-White. All handset models easily mount right on the wall or over a single gang flush electrical back box. All handset models can also be mounted over our optional AP001 or AP777 adaptor plates, when installing the handsets over an existing oversized flush intercom back box.
