You
may
also
use
your
existing
doorbell
wires
to
connect
your
doorphone
to
the
Controller.
These
Controllers
deliver
great
performance
with
clear
audio
and
strong
speaker
volume
like
not
other.
With
these
telephone
door
entry
systems,
there
is
no
hassle of complicated fine tune adjustments to the door
station(s)
in
order
to
prevent
feedback noise. No connection to your
existing doorbell button, you don't
need it. No initiation tone control to set up in order to avoid conflict with other
equipments. No number-of-rings switch to adjust. No wire polarity to take care of.
No
risk
of
burning
out
the
equipment
if
wires
are
connected
in
reverse.
No separate
anunciator. You hook up all your doorphones in parallel to one single
port on the unit! Period.
However,
if
you
prefer
individual
doorphone
connections,
then
add
the
QX-3
module
to
your
package.
No other
available
home
door
entry
equipment will give you that
much
in
such
a
simple
form in
a
package!
