IMPORTANT NOTICE
ALARM SYSTEM LIMITATIONS
This
security
system
can
not
offer
guaranteed
protection
against
burglary,
fire,
or
other
emergencies.
Any
alarm
system,
whether
commercial
or
residential,
is
subject
to
compromise
or
failure
to
warn
for
a
variety
of
reasons.
For
example:
•
Intruders
may
gain
access
through
unprotected
openings
or
have
the
technical
sophistication
to
bypass
an
alarm
sensor
or
disconnect
an
alarm
warning
device.
•
Intrusion
detectors
(sensors)
do
not
work
without
power.
Battery
operated
devices
do
not
work
without
batteries,
with
dead
batteries,
or
if
the
batteries
are
not
put
in
properly.
Devices
powered
solely
by
AC
do
not
work
if
their
AC
power
supply
is
cut
off
for
any
reason,
however
briefly.
•
Signals
sent
by
wireless
sensors
may
be
blocked
or
reflected
by
metal
before
they
reach
the
alarm
Control
Panel,
even
if
the
signal
path
has
been
recently
checked
during
a
weekly
test.
Blockage
can
occur
if
a
metal
object
has
been
moved
into
the
sensor’s
signal
path.
•
A
user
may
not
be
able
to
reach
a
panic
or
emergency
button
quickly
enough.
•
Telephone
lines
needed
to
transmit
alarm
signals
from
a
premises
to
a
Central
Station
may
be
out
of
service
or
temporarily
out
of
service.
Telephone
lines
are
also
subject
to
compromise
by
sophisticated
intruders.
•
Even
if
the
system
responds
to
the
emergency
as
intended,
however,
occupants
may
have
insufficient
time
to
protect
themselves
from
the
emergency
situation.
In
the
case
of
a
monitored
alarm
system,
authorities
may
not
respond
appropriately.
•
Alarm
warning
devices
such
as
sirens,
bells
or
horns
may
not
alert
people
or
wake
up
sleepers
if
they
are
located
on
the
other
side
of
closed
or
partly
open
doors.
If
warning
devices
sound
on
a
different
level
of
the
residence
from
the
bedrooms,
then
they
are
less
likely
to
waken
or
alert
people
inside
the
bedrooms.
Even
persons
who
are
awake
may
not
hear
the
warning
if
the
alarm
is
muffled
from
a
stereo,
radio,
air
conditioner,
or
other
appliance,
or
by
passing
traffic.
Finally,
alarm
warning
devices,
however
loud,
may
not
warn
hearing
‐
impaired
people
or
awaken
deep
sleepers.
•
While
smoke
detectors
have
played
a
key
role
in
reducing
residential
fire
deaths,
they
may
not
activate
or
provide
early
warning
for
a
variety
of
reasons
in
as
many
as
35%
of
all
fires,
according
to
data
published
by
the
Federal
Emergency
Management
Agency.
Some
of
the
reasons
smoke
detectors
used
in
conjunction
with
this
system
may
not
work
are
where
smoke
cannot
reach
the
detectors,
such
as
in
chimneys,
in
walls,
or
roofs,
or
on
the
other
side
of
closed
doors.
Smoke
detectors
may
have
been
improperly
installed
and
positioned.
Smoke
detectors
may
not
sense
fires
that
start
where
smoke
cannot
reach
the
detectors,
such
as
in
chimneys,
in
walls,
or
roofs,
or
on
the
other
side
of
closed
doors.
Smoke
detectors
also
may
not
sense
a
fire
on
another
level
of
a
residence
or
building.
A
second
floor
detector,
for
example,
may
not
sense
a
first
floor
or
basement
fire.
Moreover,
smoke
detectors
have
sensing
limitations.
No
smoke
detector
can
sense
every
kind
of
fire
every
time.
In
general,
detectors
may
not
always
warn
about
fires
caused
by
carelessness
and
safety
hazards
like
smoking
in
bed,
violent
explosions,
escaping
gas,
improper
storage
of
flammable
materials,
overloaded
electrical
circuits,
children
playing
with
matches,
or
arson.
Depending
upon
the
nature
of
the
fire
and/or
the
locations
of
the
smoke
detectors,
the
detector,
even
if
it
operates
as
anticipated,
may
not
provide
sufficient
warning
to
allow
occupants
to
escape
in
time
to
prevent
injury
or
death.
•
This
equipment,
like
other
electrical
devices,
is
subject
to
component
failure.
Even
though
this
equipment
is
designed
to
last
as
long
as
ten
years,
the
electronic
components
could
fail
at
any
time.
