WARNING

Please Read Carefully

Note to Installers

This warning contains vital information. As the only individual in contact

with system users, it is your responsibility to bring each item in this warning

to the attention of the 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 emer-

gencies 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:

Inadequate Installation

A security system must be installed properly in order to provide adequate

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.

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 a security system be reviewed periodically to ensure that its

features remain effective and that it be updated or replaced if it is found that

it does not provide the protection expected.

Access by Intruders

Intruders may enter through an unprotected access point, circumvent a

sensing device, evade detection by moving through an area of insuff i-

cient coverage, disconnect a warning device, or interfere with or pre-

vent the proper operation of the system.

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 in-

stalled 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 fluctua-

tions 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.

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 fluctua-

tions 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.

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.

System Users

A user may not be able to operate a panic or emergency switch possibly due

to permanent or temporary physical disability, inability to reach the device

in time, or unfamiliarity with the correct operation. It is important that all

system users be trained in the correct operation of the alarm system and that

they know how to respond when the system indicates an alarm.

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, escaping gas,

improper storage of flammable materials, overloaded electrical circuits, chil-

dren 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.

Motion Detectors

Motion detectors can only detect motion within the designated areas as

shown in their respective installation instructions. They cannot discrimi-

nate 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, ceil-

ings, 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 tempera-

ture. However their effectiveness can be reduced when the ambient tem-

perature 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, barbeques, fireplaces, sun-

light, steam vents, lighting and so on.

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 awak-

ened. Audible warning devices may be interfered with by other noise

sources such as stereos, radios, televisions, air conditioners or other ap-

pliances, or passing traffic. Audible warning devices, however loud, may

not be heard by a hearing-impaired person.

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.

Insufficient Time

There may be circumstances when the system will operate as intended, yet the

occupants will not be protected from the emergency due to their inability to

respond to the warnings in a timely manner. If the system is monitored, the

response may not occur in time to protect the occupants or their belongings.

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.

Inadequate Testing

Most problems that would prevent an alarm system from operating as in-

tended can be found by regular testing and maintenance. The complete sys-

tem 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 con-

struction 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.

Security and Insurance

Regardless of its capabilities, an alarm system is not a substitute for prop-

erty or life insurance. An alarm system also is not a substitute for prop-

erty owners, renters, or other occupants to act prudently to prevent or mini-

mize the harmful effects of an emergency situation.
