While this System is an advanced wireless 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 vari-
ety 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 with-
out 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 acti-
vate 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 de-
tector, 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 bed-
rooms, 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.
• Telephone lines needed to transmit alarm signals from a premises to a central monitoring 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 them-
selves 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 20 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 (used in some systems) 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.
