or spraying of any material on the lenses, mirrors, windows or any other part of the detection
system will impair its proper operation.
Passive infrared motion detectors operate by sensing changes in temperature. However, their
effectiveness can be reduced when the ambient temperature rises near or above body temperature
or if there are intentional or unintentional sources of heat in or near the detection area. Some of
these heat sources could be heaters, radiators, stoves, barbeques, fireplaces, sunlight, steam vents,
lighting and so on.
Warning Devices
Warning devices such as sirens, bells, horns, or strobes may not warn people or waken someone
sleeping if there is an intervening wall or door. If warning devices are located on a different level
of the residence or premise, then it is less likely that the occupants will be alerted or awakened.
Audible warning devices may be interfered with by other noise sources such as stereos, radios,
televisions, air conditioners or other appliances, or passing traffic. Audible warning devices,
however loud, may not be heard by a hearing-impaired person.
Telephone Lines
If telephone lines are used to transmit alarms, they may be out of service or busy for certain
periods of time. An intruder may cut the telephone line or defeat its operation by more
sophisticated means which may be difficult to detect.
Insufficient Time
There may be circumstances when the system will operate as intended, yet the occupants will
not be protected from the emergency due to their inability to respond to the warnings in a timely
manner. If the system is monitored, the response may not occur in time to protect the occupants or
their belongings.
Component Failure
Although every effort has been made to make this system as reliable as possible, the system may
fail to function as intended due to the failure of a component.
Inadequate Testing
Most problems that would prevent an alarm system from operating as intended can be found by
regular testing and maintenance. The complete system should be tested weekly and immediately
after a break-in, an attempted break-in, a fire, a storm, an earthquake, an accident, or any kind of
construction activity inside or outside the premises. The testing should include all sensing devices,
keypads, consoles, alarm indicating devices and any other operational devices that are part of the
system.
Security and Insurance
Regardless of its capabilities, an alarm system is not a substitute for property or life insurance.
An alarm system also is not a substitute for property owners, renters, or other occupants to act
prudently to prevent or minimize the harmful effects of an emergency situation.
