940A and 7110
The Alpha Communications®/Elvox™ 940A and 7110
handsets are part of a Digital Electronic Audio Door Entry
System that can be used in Luxury Apartment Buildings,
Assisted Living Facilities, Dormitories, Health Care
Facilities, Hotels, Motels, Schools, Offices, Bowling Alleys
and Supermarkets. The 955 and 7110 series are advanced
handsets, using a 4-digit electronic (Digi-Bus™) system
with user code programming directly from entrance panel
or switchboard. The Digi-Bus™ system is ideal for large
building units because many installation problems have
been solved by eliminating the use of switching modules,
and its large capacity of 9,999 remote handsets.
Choose from the 940A styling or 7110 styling to suit your
