The Alpha Communications® / S.T.R. Sentryvox™ 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, Supermarkets and for Elevator Emergency use. Sentryvox™ is an advanced 2-wire system, with latching lamp annunciation, conversation privacy, and a host of optional features.
Any number of 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 a lobby panel, and activate a lobby electric door release. Model HT2009/2 handsets are available in White, Grey, Ivory or Brown and model HT3009/2 handsets are available in White or Anthracite, and easily mount right on the wall or over a single gang flush electrical back box. Handsets can be changed to a desk mount or flush wall type with the addition of a low-cost adapter.
For part-time switchboard operation, calls to remote handsets can be transferred to a conventional lobby/entrance intercom panel. Calls placed from this type of panel are common-talk, and enable the remote handsets to allow entry to the building by electric door release (on the same 2-wires!).
