Automatic Ringdown Line
Model 46220 & 46240 Telephone Hot Lines
|
|
| The
Proctor Model 46220 Telephone Hot Line provides a private
automatic-ringing telephone line between two telephones
without using telco facilities or special equipment and
power. When one of the two connected phones goes off-hook,
the other phone automatically rings. The unit features
user-selectable one-way or two-way ringdown operation and
three different ringing patterns. The 46220 is ideal for
facilities requiring immediate uninterrupted communications,
such as military bases, emergency service centers, entry
gates and guard shacks, school campuses, hotel/motel
complexes, retail stores, large business offices and private
residences. It can also be interfaced with multiline
telephone systems to provide a special executive priority
line with absolute privacy and independence from other
lines.
How It Works
The 46220 is a stand-alone direct line
telephone circuit that works independently of the public
switched telephone network. The 46220 is completely self
contained, providing its own source of 48VDC line power and
20 Hz ringing. The user simply plugs the unit into the
nearest standard AC outlet, plugs in the line cords of the
two telephones, and lifts the handset of one phone to
automatically ring the other. The user can manually select
either one-way or two-way ringdown and the desired ringing
pattern via switches on the front faceplate. It includes
RJ11 modular jacks for quick connection of the telephone
line cords. The 46220 can be used with standard, cordless
and multiline telephones, or for transmitting data via
modems or FAX machines. It is ideal for use as a dedicated
telephone-to-telephone hot line, a tie line between two key
or PBX systems, or as an Off-Premise Extension (OPX). It c
