One
Set
of
NAV
Con
Two
Readers
–
Control
of
both
Entry
and
Exit
When
the
security
grade
is
relatively
high
or
the
administrator
requires
the
card
holders
to
get
in
or
out
at
fixed
time
or
date
through
specific
door,
two
sets
of
EFC301
are
needed.
Additional
installation
of
one
set
of
EFC301
on
the
side
of
the
door
requires
the
card
holders
to
swipe
the
card
when
exiting
and
entering.
This
rule
has
more
reliable
security
regarding
who
can
enter
and
who
can
exit
and
the
administrator
canal
so
master
the
entry
and
exit
time
of
card
holders.
2.1.3
Determine
the
Number
of
Controllers/
Modules
According
to
System
Structure
Determine
how
many
controllers
/
modules
and
network
interface
are
required.
1.
Each
NAV
controller
can
accommodate
up
to
8
readers.
If
the
system
to
be
installed
requires
more
than
8
readers,
additional
controllers
are
necessary.
E.g.
Flex
series
controllers.
2.
If
one
or
more
controllers
are
installed
at
a
different
location,
then
the
system
computer
is
to
be
installed,
and
an
Ethernet
interface
is
required
to
connect
over
the
internet.
An
Ethernet
interface
may
also
be
used
in
locations
at
which
the
controllers
are
installed
a
long
distance
away
from
the
system
computer.
Software
is
required
to
manage
these
NAV
controllers.
2.2
Hardware
Installation
After
the
preparation
work
is
finished,
user
can
start
installation.
This
chapter
mainly
introduces
how
to
install
the
hardware
part,
which
is
divided
into
six
steps:
1.
Mounting
the
enclosure
(optional)
and
controller.
2.
Installing
and
connecting
the
readers.
3.
Connecting
to
door
lock,
sensor
and
open
button.
4.
Connecting
to
the
alarm
input
/
output.
5.
Connecting
to
the
computer.
6.
Mounting
a
backup
battery
in
the
enclosure
(optional).
2.2.1
Mounting
the
Enclosure
(Optional)
and
Controller
The
NAV
controller
should
be
installed
in
an
easily
‐
accessible
position.
However,
it
should
be
noticed
that
the
controller
is
the
core
part
of
the
entire
system
and
can
be
used
to
change
database.
After
the
installation
site
is
selected,
a
relative
secure
clean
position
in
which
the
administrator
is
easy
to
operate
should
be
selected.
Due
to
the
controller
is
an
essential
part
of
the
access
control
system.
It
is
recommended
to
mount
the
NAV
controller
in
a
metal
enclosure
(EPN
‐
871
‐
B).
If
you
are
using
the
enclosure,
additional
AC
power
supply
is
required.
The
enclosure
uses
a
24V
AC
power
supply
with
a
built
‐
in
15V
DC
converter.
If
the
system
requires
additional
door
or
alarm
modules,
install
them
in
the
controller
before
mounting
the
controller
in
the
enclosure
or
on
the
wall.
