Because
the
Controller
intercepts
the
home
phone
line
at
the
very
head
of
it,
it
is
not
concerned
with
the
way
the
wires
are
run
inside
the
home.
You
never
have
to
change
or
adopt
a
particular
form
of
wiring
to
suit
the
intercom
Controller.
In
many
homes,
the
head
Telephone
Block
is
a
jack.
That
makes
it
even
easier
to
intercept
the
line
by
using
two
standard
phone
cords
(cords
with
transparent
plugs
at
the
ends),
and
complete
your
installation
without
any
tooling
whatsoever!
Guaranteed.
These
systems
are
therefore
fit
for
any
real
estate
situation
for
the
most
part:
homes
being
built,
new
home
already
built
or
existing.
For
a
system
that
always
installs
in
a
totally
plug
and
play
fashion,
see
the
Ultimatoll
Premium
systems.
If
you
have
a
doorphone
on
your
system,
still
only
one
twisted
pair
is
required
for
connection
to
the
Intercom
Controller. If
you
have
more
than
one
doorphone,
it
is
again
one
twisted
pair
from
each
doorphone
running
into
the
Controller.
You
may
also
alternatively
use
your
existing
doorbell
wires
to
connect
your
doorphone
to
the
Controller,
if
you
want
to
avoid
running
new
wires
at
all.
This
is
why
these
telephone
intercom
systems
are
so
easy
to
install
by
the
very
homeowner.
If
you
have
a
contractor
on
the
job,
expect
minimum
charges
because
there
is
very
little
to
do.
With
these
telephone
intercom
systems,
there
is
little
to
do
because
there
is
no wire
line polarity to take care
of
at
the
risk
of
burning
out
the
equipment
if
wires
are
connected
in
reverse.
It
is
one
Line
In
and
one
Line
Out! No initiation tone control to set up in order to avoid conflict with other
equipments. No number-of-rings switch to
adjust.
No
complicated fine tune adjustments to the door
station(s)
in
order
to
prevent
feedback
squeal. No connection to your
existing doorbell button, you don't
need
it
anymore.
No separate
anunciator.
No other
available
home
intercom
system
will give you that
much
in
such
a
simple
form in
a
package!
