N ot e t o I n st a ll e r s
This Warning contains vital information. As the only individual in
contact with system users, it is the installer's responsibility to bring
each item in this Warning to the attention of all users of this system.
S y s t e m Fai l u r e s
This system has been carefully designed to be as effective as possi-
ble. 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 these reasons may be:
Access by Intruders
Intruders may enter through an unprotected access point, circum-
vent a sensing device, evade detection by moving through an area of
insufficient coverage, disconnect a warning device, or interfere with
or prevent 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
failure 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
effective at the time of manufacture. It is possible for persons with
criminal intent to develop techniques which reduce the effectiveness
of these features. It is important that your 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
battery life is a function of the device environment, usage, and type.
Ambient 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
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.
Inadequate Installation
A security system must be installed properly in order to provide ade-
quate protection. Every installation should be evaluated by a security
professional to ensure that all access points and areas are covered.
Locks and latches on windows and doors must be secure and oper-
ate as intended. Windows, doors, walls, ceilings and other building
materials 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 department 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
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.
Insufficient Time
There may be circumstances when the system will operate as
intended, 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 system is remotely monitored, the response may not occur in
time to protect the occupants or their belongings.
WARNING
Please Read Carefully
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 mul-
tiple beams of detection and motion can only be detected in unob-
structed areas covered by these beams. They cannot detect motion
which occurs behind walls, ceilings, floor, closed doors, glass parti-
tions, glass doors or windows. Any type of tampering whether inten-
tional 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, radia-
tors, stoves, barbeques, 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 opera-
tion. If a device operates from batteries, it is possible for the batter-
ies 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
inoperative while it does not have power. Power interruptions of any
length are often accompanied by voltage fluctuations which may
damage electronic 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 fol-
low. 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 cir-
cumstances when there is insufficient warning to allow all occu-
pants to escape in time to avoid injury or death.
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.
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 per-
son.
