System Failures
This system has been carefully designed to be as effective as possible.
There are circumstances, however, involving fire, burglary, or other
types of emergencies where it may not provide protection. Any alarm
system of any type may be compromised deliberately or may fail to
operate as expected for a variety of reasons. Some, but not all, of the
reasons may be:

There are circumstances, however, involving fire, burglary, or other

operate as expected for a variety of reasons. Some, but not all, of the
reasons may be:
Access by Intruders
Intruders may enter through an unprotected access point, circumvent a
sensing device, evade detection by moving through an area of insuf-
ficient coverage, disconnect a warning device, or interfere with or pre-
vent the proper operation of the system.

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 fail-
ure of a component.

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 delib-
erate jamming or other inadvertent radio signal interference.

Criminal Knowledge
This system contains security features which were known to be effect-
ive at the time of manufacture. It is possible for persons with criminal
intent to develop techniques which reduce the effectiveness of these fea-
tures. It is important that the security system be reviewed periodically
to ensure that its features remain effective and that it is updated or
replaced if it is found that it does not provide the protection expected.

Failure of Replaceable Batteries
This system’s wireless transmitters have been designed to provide
several years of battery life under normal conditions. The expected bat-
tery life is a function of the device environment, usage, and type. Ambi-
ent conditions such as high humidity, high or low temperatures, or
large temperature fluctuations may reduce the expected battery life.
While each transmitting device has a low battery monitor which iden-
tifies 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.

Inadequate Installation
A security system must be installed properly in order to provide
adequate protection. Every installation should be evaluated by a secur-
ity professional to ensure that all access points and areas are covered.
Locks and latches on windows and doors must be secure and operate
as intended. Windows, doors, walls, ceilings and other building mater-
ials must be of sufficient strength and construction to provide the level
of protection expected. A reevaluation must be done during and after
any construction activity. An evaluation by the fire and/or police depart-
ment is highly recommended if this service is available.

Inadequate Testing
Most problems that would prevent an alarm system from operating as
intended can be found by regular testing and maintenance. The com-
plete 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.

Insufficient Time
There may be circumstances when the system will operate as inten-
ded, yet the occupants will not be protected from an emergency due to
their inability to respond to the warnings in a timely manner. If the sys-
tem is remotely monitored, the response may not occur in time to pro-
tect the occupants or their belongings.

Motion Detectors
Motion detectors can only detect motion within the designated areas as
shown in their respective installation instructions. They cannot dis-
criminate between intruders and intended occupants. Motion detectors
Motion detectors can only detect motion within the designated areas as
shown in their respective installation instructions. They cannot dis-
criminate 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 tem-
perature. However their effectiveness can be reduced when the ambi-
ent 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, bar-
becues, fireplaces, sunlight, steam vents, lighting and so on.

Power Failure
Control units, intrusion detectors, smoke detectors and many other
security devices require an adequate power supply for proper oper-
ation. If a device operates from batteries, it is possible for the batteries
to fail. Even if the batteries have not failed, they must be charged, in
good condition and installed correctly. If a device operates only by AC
power, any interruption, however brief, will render that device inop-
erative while it does not have power. Power interruptions of any length
are often accompanied by voltage fluctuations which may damage elec-
tronic equipment such as a security system. After a power interruption
has occurred, immediately conduct a complete system test to ensure
that the system operates as intended.

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.

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 explo-
sions, escaping gas, improper storage of flammable materials, over-
loaded electrical circuits, children playing with matches, or arson.
Even if the smoke detector operates as intended, there may be cir-
cumstances when there is insufficient warning to allow all occupants to
escape in time to avoid injury or death.

Telephone Lines
If telephone lines are used to transmit alarms, they may be out of ser-
vice 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.

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,
other appliances, or passing traffic. Audible warning devices, however
loud, may not be heard by a hearing-impaired person.
