RECESSED DOOR CONTACT
INSTALLATION INSTRUCTIONS
The
2GIG
Recessed
Door
Contact
(2GIG
‐
DW20R
‐
345)
is
the
industry’s
most
flexible
supervised
door
contact.
It
communicates
with
the
2GIG
Control
Panel
using
the
345
MHz
wireless
frequency.
It
also
allows
a
multitude
of
applications
while
hiding
the
transmitter
within
a
door
or
window
frame.
It
is
powered
by
a
replaceable
lithium
battery,
which
should
last
five
(5)
years
under
normal
usage.

Installation Guidelines
Before
mounting
the
door
contact
to
the
desired
location,
test
the
sensor
to
verify
that
it
can
establish
good
radio
frequency
(RF)
communications
with
the
control
panel.
NOTE:
To
learn
how
to
program
a
wireless
sensor
into
the
Control
Panel
and
for
testing
information,
see
the
Control
Panel’s
Installation
&
Programming
Guide
.
Guidelines
include:
•
Mount
Sensors
within
100
ft
(30
m)
of
the
Control
Panel
.
Although
the
transmitter
may
have
a
range
of
450
ft
(137.2
m)
in
open/unobstructed
situations,
the
environment
at
the
installation
site
can
have
a
significant
effect
on
transmitter
range.
•
Install
the
Recessed
Sensor
in
the
Door
or
Door
Frame
.
It
is
important
to
select
the
proper
placement
of
the
recessed
sensor/
transmitter
and
magnet.
The
sensor
comes
with
two
different
tops,
however,
the
screw
mount
is
recommended
for
securing
the
sensor
to
a
door
frame.
The
magnet
does
not
have
a
second
top
with
a
flange
to
screw
it
into
place
so
you
must
be
extremely
careful
to
ensure
that
the
magnet
is
tightly
in
place
upon
installation.

The
door
contact
can
be
mounted
in
either
the
door
jamb
or
door
frame.
The
best
practice
is
to
mount
it
in
the
door
frame.

frame,
follow
these
steps:
1a
Use
a
pencil
to
mark
the
location
for
the
sensor
and
magnet.
1b
Drill
two
(2)
holes
directly
across
from
each
other.
NOTE:
It
is
important
to
ensure
these
holes
are

Using
an
11/16"
drill
bit,
follow
these
steps:
2a
Slowly
drill
the
first
hole
for
the

into
the
door
or
frame.
NOTE:
Take
care
to
slowly
route
the
hole
to
ensure
the
snuggest
possible
fit.
The
sensor
diameter
is
specifically
designed
to
be
slightly
larger
than
11/16".
2b
Use
the
flanged
cap
with
the
included
screws
to
mount
the
