851/001 Series Handset Intercom System

The Alpha Communications® / Elvox 851/001 Series handsets are primarily designed to work as an office type handset intercom station, where up to 40 master handsets can selectively call each other, in complete privacy. Each system can have up to four (4) simultaneous talk paths (links). 

These attractive handsets easily surface mount right on the wall or over a single gang flush electrical back box (or plaster ring). The 851/001 handsets can be changed to desk mount with the addition of a model 2/805 desk adapter

The 851/001 series handsets feature handset to handset signaling and 16 selective button switches for handset to handset signaling, and optional paging and door release. 

With the addition of a low-cost 2/850 call adapter, each 851/001 handset can be signaled by a remote door intercom station (model 2900/001 or 2970/001 or equivalent).
