WARNING!THE LIMITATIONS OF THIS ALARM SYSTEM
While this system is an advanced design security system, it does not offer guaranteed protection
against burglary or fire or other emergency. Any alarm sys te m, whether commercial or residential, is
subject to compromise or failure to warn for a variety of re asons. For example:
•Intruders may gain access through unprotected openings or have the technical sophisti cation to
bypass an alarm sensor or disconnect an alarm warning device.
•Intrusion detectors (e.g., passive infrared detectors), smoke detectors, and many 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 powe red solely by AC will
not work if their AC power supply is cut off for any reason, however b riefly.
•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 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 Manageme nt 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 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 all
occupants to escape in time to prevent injury or death.
•Passive Infrared Motion Detectors can detect intrusion only within the designed ranges as
diagrammed in their installation manual. Passive Infrared Detectors do not provide volumetric
area protection. They do create multiple beams of protection, and intrusion can only be detected in
unobstructed areas covered by those beams. They cannot detect motion o r intrusion that takes
place behind walls, ceilings, floors, closed doors, glass partitions, glass 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 detection ability. Passive Infrared Detectors sense
changes in temperature; however, as the ambient temperature of protected area approaches the
temperature range of 90° to 105°F, the detection performance can decrease.
