WARNING Please Read Carefully

Note to Installers

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.

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 these

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 warn-

ing 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 deliberate 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 per-

sons 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 condi-

tions. 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 tempera-

ture 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 moni-

tor may fail to operate as expected. Regular testing and

maintenance will keep the system in good operating condi-

tion.

Inadequate Installation

A security system must be installed properly in order to pro-

vide adequate protection. Every installation should be eval-

uated by a security professional to ensure that all access

points and areas are covered. Locks and latches on win-

dows 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 evalua-

tion 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 opera-

tional 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 desig-

nated areas as shown in their respective installation instruc-

tions. They cannot discriminate between intruders and

intended occupants. Motion detectors do not provide volu-

metric 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 par-

titions, glass doors or windows. Any type of tampering

whether intentional or unintentional such as masking, paint-

ing, or spraying of any material on the lenses, mirrors, win-

dows 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 unin-

tentional sources of heat in or near the detection area.

Some of these heat sources could be heaters, radiators,

stoves, barbeques, fireplaces, sunlight, steam vents, light-

ing, 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 bat-

teries, it is possible for the batteries to fail. Even if the bat-

teries 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 volt-

age 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 sub-

stitute for property or life insurance. An alarm system also is

not a substitute for property owners, renters, or other occu-

pants 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 explosions, escap-

ing 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 circumstances 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 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 con-

ditioners or other appliances, or passing traffic. Audible

warning devices, however loud, may not be heard by a

hearing-impaired person.
