LIMITATIONS OF THIS ALARM SYSTEM
While this System is an advanced design security system, it does not offer guaranteed protection against burglary, fire
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 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 powered solely by AC will not work if their AC power supply is cut off for
any reason, 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 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
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. Finally, 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 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.
•
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. They do create multiple
beams of protection, and intrusion can only be detected in unobstructed areas covered by those beams. They
cannot detect motion or 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 the protected area approaches the temperature range of
90° to 105°F (32° to 40°C), 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 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 appliance, or by passing traffic. Finally, alarm warning devices, however loud, may not warn hearing-
impaired people.
•
Communication paths needed to transmit alarm signals from a premises to a central monitoring station may be out
of service or temporarily out of service. Communication paths are also subject to compromise by sophisticated
intruders.
•
Even if the system responds to the emergency as intended, 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.
•
This equipment, like other electrical devices, is subject to component failure. Even though this equipment is
designed 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. The security keypad (and remote keypad) should be tested as well.
Wireless transmitters are designed to provide long battery life under normal operating conditions. Longevity of
batteries may be as much as 4 to 7 years, depending on the environment, usage, and the specific wireless device being
used. External factors such as humidity, high or low temperatures, as well as large swings in temperature, may all
reduce the actual battery life in a given installation. This wireless system, however, can identify a true low battery
situation, thus allowing time to arrange a change of battery to maintain protection for that given point within the
system.
Installing an alarm system may make the owner eligible for a lower insurance rate, 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.
