System Users; Motion Detectors; Warning Devices; Security And Insurance - DSC HS2032 Installation Manual

While each transmitting device has a low battery monitor which identifies when the
batteries need to be replaced, this monitor may fail to operate as expected. Regular
testing and maintenance will keep the system in good operating condition.
Compromise of Radio Frequency (Wireless) Devices
Signals may not reach the receiver under all circumstances which could include metal
objects placed on or near the radio path or deliberate jamming or other inadvertent radio
signal interference.

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. 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 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.
