Obtaining
a
floor
plan
helps
the
installer
determine
what
components
need
to
be
installed,
and
where.
It
also
is
essential
in
determining
the
length
of
cable
needed
to
connect
readers
to
the
controller.
A
floor
plan
can
be
a
blue
of
the
building,
a
design,
or
simply
a
drawing
of
the
facility.
Any
document
showing
the
footprint
of
the
building
can
be
used.
The
dimensions
are
important
to
note,
especially
when
determining
cable
lengths.
A
floor
plan
may
be
obtained
from
your
local
city
hall.
2.1.2
Determine
the
Hardware
and
Location
Determine
which
hardware
to
use
and
where
it
will
be
installed.
This
is
the
most
crucial
step
in
the
preparation
stage.
First,
determine
how
many
access
points,
or
doors,
need
to
be
managed
by
the
access
control
system.
These
access
points
will
control
the
security
of
the
facility,
and
can
limit
the
entry
and
exit
to
and
from
any
given
area
of
the
building.
After
deciding
which
doors
need
to
be
controlled,
the
user
must
also
determine
the
level
of
security
needed
at
each
door.
There
are
many
ways
to
manage
each
door,
using
different
resources.
These
resources
include,
but
are
not
limited
to:
proximity
readers,
mag
strip
readers,
relays,
and
request
to
exits.
A
few
common
door
configurations
are
described
below:
One
Set
of
NAV
Con
One
Reader
–
The
Basic
Door
Entry
Control
The
most
basic
configuration
involves
one
NAV
controller,
a
reader
and
an
electric
strike.
In
this
configuration,
a
person
presents
a
card
to
the
reader,
and
is
either
granted
or
denied
access.
The
electric
strike
unlocks
if
the
system
grants
access.
Another
variation
of
this
scenario
involves
setting
the
system
up
to
monitor
whether
the
door
is
open,
which
allows
the
system
to
protect
against
propped
open
doors,
or
doors
being
held
open
for
too
long.

–
Control
of
Exit
Adding
a
door
open
button
to
the
above
scenario
allows
the
system
to
control
when
to
allow
people
to
exit
through
a
door.
The
door
open
button
equipment
includes
a
button
which
has
to
be
pressed
when
a
card
holder
exits,
or
a
door
sensor.
The
equipment
should
be
arranged
on
the
secure
side
of
the
door.
