to
mount
the
unit
less
than
40cm

Walk Test
A
walk
test
determines
the
coverage
pattern
of
the
detector.
To
perform
this
test,
walk
across
the
scope
of
the
detector
according
to
the
detection
pattern
selected.
Confirm
that
the
LEDs
activate
and
deactivate
as
described
in
Table
B
‐
5.
To
launch
the
Walk
Test
from
the
Radio
mode,
after
any
transmission
indicated
by
LED
blinking,
press
the
tamper
switch
and
hold
it
until
the
green
LED
turns
on
then
off
(see
Figure
B

step
1).
Release
the
tamper
switch
and
wait
until
the
red
LED
turns
on
and
then
off
(see
Figure

Press
the
tamper
switch
once
again.
Both
LEDS
are
lit
momentarily
(see
Figure

The
detector
enters
the
Walk
Test
mode
for
4
minutes.
During
the
Walk
Test,
wait
for
twenty
seconds
between
movements.
To
launch
the
Walk
Test
from
the
Normal
mode:
Just
open
the
detector
housing:
the
tamper
is
triggered
and
the
detector
enters
the
Walk
Test
mode
for
4
minutes.
Walk
test
should
be
performed
weekly.
In
Walk
Test
mode
there
are
no
delays.
