In existing installations, you will generally be
able to run the system with all
of
your
existing
phones,
in
general
a minimum of
8 phones.
You can always
have
more depending on
their
REN.
Preferably
avoid
phones
with
REN
of
1.0
or
above
(very
high!)
when
you
need
to
install
a
large
number
of
phones. The
REN
(short
for
Ringer
Equivalence
Number)
is
a
number
that
specifies
the
load
that
the
phone
set
places
on
the
line
on
incoming
calls.
It
is
written
at
the
bottom
of
every
phone
set.
Your total REN
should not
exceed
7.0
with
these
intercom
systems.
For
instance,
if you
pick
phones
with REN
of
0.4 or
below, you can easily install around
16 extension
phones
of
any
kind
around
your
home. For multi-handset wireless phones, the REN only applies to the
base phone set. Also
beware
that
phones with Ringer Equivalence Number
(REN) of
0.0
are
very
common.
These
will
remove
all
expansion
limitations!
So
how
many
phones
can
you
install
with
these
systems?
There is virtually
no limit
to the number
of extension
phones you can install with
the
MiniCom
systems! With
these
systems you set your own limit. The greatest flexibility! With
all other systems, Key Systems,
KSU-less
or
wireless,
you can never go beyond the preset number of
extension phones or ports they are designed to
handle. In addition, costs increase
significantly beyond the basic set of ports. Save big with the MiniCom! So it does not
matter the size of your new or remodeled home, you will be able to put a
convenient
intercom
phone wherever
you please with
these telephone intercom
systems.
