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:
• 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.
• 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 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 20 years, the electronic components could fail at any time.
