Connect multiple CO lines . . . and get
one common output whenever one of the lines is ringing
The
Models 173, Common Ringer Matrice, allow for connecting multiple
Central Office (CO) lines together to provide one common output
whenever one of the lines ring. This unit eliminates the necessity
of providing one bell for each incoming CO line. The Model
173 will accommodate three CO lines and for more than 3 lines
you can gang 173's together.
The
173 unit is very easy to install. Screw terminals allow
simple bridge tap connections to the incoming CO lines. With
no external power required, just about any common audible
device (tip and ring powered ringer) will work.
The
173 provides a choice of two outputs, standard ringing voltage
or contact closure. Also, the 173 offers special features
that allow for multiple unit connections, i.e., expanding
beyond three CO lines. Units can be ganged together to accommodate
additional CO lines. They also
have an auxiliary dry relay contact for operating ancillary
equipment, i.e., through the use of a power supply connected
to the optional contact closure, a 24 VDC alert signal can
be driven.
Application
The perfect solution for organizations that require common
audible or night bells. Economize on the cost of installing
one bell for each line. The Model 173 allows you to connect
all your lines to one bell. Make sure calls are heard when
your receptionist goes home. In loud industrial areas, combine
with Dees’ Model 196, Loud Industrial Ringer. Use the
dry relay contacts to operate auxiliary equipment. For example,
through the use of a power supply connected to the optional
contact closure, you can drive a 24 VDC lamp. This application
would be suitable for locations that require visible rather
than audible notification of a call, such as recording studios,
nurses stations, or the hard of hearing.
