The Alpha Communications/Elvoxў 845 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 845 series is an advanced 5-wire (loop) system, with dual LED annunciation, conversation privacy, and 800 remote handset capacity. Up to 800 remote handsets can be used and all handsets can call to the switchboard (in full communication privacy), talk with another remote handset, receive a call from an optional lobby intercom panel, and activate a lobby electric door release. Model 870/845 handsets are two-tone White/Black and easily mount right on the wall or over a single gang flush electrical back box. For part-time switchboard operation, calls to remote handsets can be transferred to a digital lobby/entrance intercom panel. All calls placed from the entry panel are private, and for added security, only the remote station called can activate the electric door release. (All of these features are available on the same 5-wires!)
