CA-200 ONLY
The Call Alert CA-200 comes as a
Master Unit and a Remote Unit
(each sold separately). The Master
Unit must be connected to a phone
line. When the phone rings, the
Master Unit will flash a connected
lamp to let you know that your
phone is ringing; at the same time it
sends out a carrier signal (through
the electrical wiring in your home) to
the Remote Unit. The Remote Unit
picks up the carrier signal and
flashes its connected lamp. The
Master Unit can operate and
function with a Master Unit. Up to
three Remote Units can be used
with a Master Unit.
