WARNING: Installer please read carefully
Note to Installers
The warnings on this page contain 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.
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 pro-
tection. 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:
Access by Intruders
Intruders may enter through an unprotected access point, circumvent a sensing device, evade
detection by moving through an area of insufficient coverage, disconnect a warning device, or inter-
fere 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 deliberate jamming or other inadvertent radio signal inter-
ference.
Criminal Knowledge
This system contains security features which were known to be effective at the time of man-
ufacture. 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 tem-
perature 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 adequate protection. Every install-
ation 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 operate as intended. Win-
dows, doors, walls, ceilings and other building materials must be of sufficient strength and con-
struction 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 recom-
mended 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 man-
ner. If the system is remotely monitored, the response may not occur in time to protect the occu-
pants or their belongings.
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 detec-
tion 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 detec-
tion 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, barbecues, 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 operation. 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 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 sys-
tem 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 num-
ber 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, escap-
ing 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 insuf-
ficient warning to allow all occupants to escape in time to avoid injury or death.
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. Aud-
ible warning devices may be interfered with by other noise sources such as stereos, radios, tele-
visions, air conditioners, other appliances, or passing traffic. Audible warning devices, however
loud, may not be heard by a hearing-impaired person.
