THE LIMITATIONS
OF TNIS
SNIOKE
DETECTOR/TRANSMl~ER
While this smoke detectorltransmitter
is a highly reliable device that is part of an
advanced wireless security system, it does not offer guaranteed
protection
against
fire.
While smoke detectors
have playad a key role in reducing
residential
fire
deaths in the United States, 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
alarm
systems may not work are as follows:
. Smoke detectors will not work without power.
Battery operated
devices will not
work without batteries, or if the batteries are not put in properly.
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 roof, 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 fire or basement fire.
In addition, smoke detectors
have sensing limitations.
No smoke detector
can
sense every kind of fire every time.
In general, detectors may not always provide
adequate
warning
about rapidly spreading
fires caused
by carelessness
and
safety hazards like smoking in bed, violent explosions,
escaping
gas, improper
storage
of flammable
materials,
children
playing
with
matches,
or arson.
Depending
on the nature of the fire and/or location of the smoke detectors,
the
detector, even if it operates as anticipated,
may not provide sufficient warning to
allow all occupants to escape in time to prevent injury or death.
Alarm signal sent by the wireless transmitter
in this device may be blocked or
reflected by metal before they reach the alarm receiver.
Even if the signal path
has been recently checked during a weekly test, blockage
can occur if a metal
object is moved into the path.
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
are located
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 by
noise from a stereo, radio, air conditioner or other appliances, or by passing traffic.
Finally, alarm warning devices,
however
loud, may not warn hearing
impaired
people or waken deep sleepers.
This smoke
detector/transmitter,
like other
electrical
devices,
is subject
to
component
failure.
Even though this device is designed
to last as long as 20
years, the electronic components
in it could fail at any time.
We recommend
that
smoke detectors be replaced every 10 years as a precautionary
measure against
component failure.
The most common cause of an alarm system not functioning
when a fire occurs is
inadequate maintenance.
The alarm system should be tested weekly to make sure
all smoke detectors and their transmitters
are working properly.
Detectors must be
repaired or repfacad when they do not function properly.
Installing an alarm system may make the owner eligible for lower insurance
rates,
but an alarm system is not a substitute
for insurance.
Homeowners,
property
owners and renters should continue to act prudently
in protecting
themselves
and
continue to insure their lives and property.
We continue
to develop
new and improved
protection
devices.
Users of alarm
systems
owe
it to themselves
and their
loved
ones
to learn
about
these
developments.
