System Users
A user may not be able to operate a panic or emergency switch possibly due to permanent or temporary physical
disability, inability to reach the device in time, or unfamiliarity with the correct operation. It is important that all
system users be trained in the correct operation of the alarm system and that they know how to respond when the
system indicates an alarm.
Smoke Detectors
Smoke detectors that are a part of this system may not properly alert occupants of a fire for a number of reasons,
some of which follow. The smoke detectors may have been improperly installed or positioned. Smoke may not
be able to reach the smoke detectors, 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 occupants 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 tampering 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, 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.
