WARNING: I

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 responsi-

bility 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 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 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 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 operate

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 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

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.

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 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,

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 opera-

tion. 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

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 posi-

tioned. 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, vio-

lent explosions, escaping gas, improper storage of flammable materi-

als, 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 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 resi-

dence 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 per-

son.
