tors, such as when the fire is in a chimney, walls or roofs, or on the other side of closed doors. Smoke detectors may not detect
smoke from fires on another level of the residence or building.
Every fire is different in the amount of smoke produced and the rate of burning. Smoke detectors cannot sense all types of fires
equally well. Smoke detectors may not provide timely warning of fires caused by carelessness or safety hazards such as smoking
in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing
with matches or arson.
Even if the smoke detector operates as intended, there may be circumstances when there is insufficient warning to allow all occu-
pants to escape in time to avoid injury or death.
Motion Detectors
Motion detectors can only detect motion within the designated areas as shown in their respective installation instructions. They
cannot discriminate between intruders and intended occupants. Motion detectors do not provide volumetric area protection. They
have multiple beams of detection and motion can only be detected in unobstructed areas covered by these beams. They cannot
detect motion which occurs behind walls, ceilings, floor, closed doors, glass partitions, glass doors or windows. Any type of tam-
pering whether intentional or unintentional such as masking, painting, 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, televi-
sions, air conditioners or other appliances, or passing traffic. Audible warning devices, however loud, may not be heard by a hear-
ing-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. Also 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 earth-
quake, 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 sub-
stitute for property owners, renters, or other occupants to act prudently to prevent or minimize the harmful effects of an emergency
situation.
