WARNING! THE LIMITATIONS OF THIS ALARM SYSTEM
While this system is an advanced design security system, it does not offer gu ara nteed protect io n aga inst bur glar y or other
emergency. 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 (e.g. passive infrared detectors), smoke detectors, and ma ny other sensing devices will not work
without power. Battery operated devices will not work without batteries, with dead batteries, or if the batteries are
not put in properly. Devices powered s olely by AC will not work if their AC p ower supply is cut off for any re ason,
however briefly.
• Signals sent by wireless transmitters 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.
• A user may not be able to reach a panic or emergency button quickly enough.
• While smoke detectors have played a key role in reducing res idential fire deat hs in the Unite d States, they m ay 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 as follows. Smoke detectors may have been improperly installed a nd positioned. Smoke
detectors may not sense fires that start where smoke cannot reach the detectors, such as in c himneys, in walls, or
roofs, or on the other side of closed doors. Sm oke detect ors als o m ay n ot sense a fire on another level of a res ide nce or
building. A second floor detector, for exam ple , may not s ense a first floor or basem ent fire. Moreover, smoke det ectors
have sensing limitations. No smoke detector can sense every kind of fire every time. I n general, detect ors may not
always warn about fires caused by carelessness and safety hazards like smoking in bed, violent explosions, escap ing
gas, improper storage of flammable materials, overloaded electric al circuits, c hildren pla ying with m atches, or arson.
Depending upon the nature of the fire and/or the locations of the smoke detect ors, the detector, even if it o perates as
anticipated, may not provide sufficient warning to allow all occupan t s to escape in time to prevent injury or death.
• Passive Infrared Motion Detectors can only detect intrusion within the designed ranges as diagrammed in their
installation manual. Passive Infrared Detectors do not provide volumetric area protection. T hey do create multiple
beams of protection, and intrusion can only be detected i n unobstructed areas covered by t hose beams. They cannot
detect motion or intrusion that t akes plac e behin d walls , ceilings, floors, close d doors, glass p artitions, g lass doors, or
windows.
Mechanical tampering, masking, painting or spraying of any material on the mirrors, windows or any part of the
optical system can reduce their detect ion ability. Passive Infrared Det ectors sense chang es in t emperature; however,
as the ambient temperature of protected area approaches the temperature range of 90° to 105°F, the detection
performance can decrease.
• 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 ope n doors. If warning devices s ound on a different le vel of the residence from the
bedrooms, then they are less likely to waken or a lert people inside t he bedrooms. Eve n persons who are awake may
not hear the warning if the al arm is muffled from a stereo, radio, air con ditioner or other appliance, or by passing
traffic. Finally, alarm warning devices, however loud, may not warn hearing-impaired people or waken deep sleepers.
• Telephone lines neede d to transmit alarm signals from a premises to a central monitoring station may be out o f
service or temporarily out of service. Telephone lines are also subject to compromise by sophisticated intruders.
• Even if the system respo nds to the em ergency as intended , however, occ upants may hav e insufficient t ime to protect
themselves from the emergency sit uation. In the case of a monitored alarm system , authorities may not respond
appropriately.
• This equipment, like ot her elect rica l devic es, is subject to component fai lure. Eve n th ou gh this equipment is des ign ed
to last as long as 10 years, the electronic components could fail at any time.
The most common cause of an alarm system not functioning when an intrusion or fire occurs is inadequate maintenance.
This alarm system should be tested weekly to make sure all sensors and transmitters are working properly.
Installing an alarm system may make one elig ible for low er insuranc e rates, but an alar m system is not a subst itute 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 devic es. Users of alarm syst ems o we it to themselves and their loved
ones to learn about these developments.
