WARNING

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 emergencies where it may not pro-

vide protection. Any alarm system of any type may be compro-

mised deliberately or may fail to operate as expected for a va-

riety of reasons. Some but not all of these reasons may be:

Inadequate Installation

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

vide adequate protection. Every installation should be evalu-

ated 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 ex-

pected. A reevaluation must be done during and after any con-

struction activity. An evaluation by the fire and/or police de-

partment 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 per-

sons with criminal intent to develop techniques which reduce

the effectiveness of these features. It is important that a secu-

rity 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, cir-

cumvent 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.

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 pos-

sible 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, how-

ever brief, will render that device inoperative while it does not

have power. Power interruptions of any length are often ac-

companied by voltage fluctuations which may damage elec-

tronic equipment such as a security system. After a power in-

terruption 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 pro-

vide 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 re-

duce 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 ex-

pected. 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

Please Read Carefully

follow. The smoke detectors may have been improperly installed

or positioned. Smoke may not be able to reach the smoke detec-

tors, 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

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 discriminate between intruders and intended occupants.

Motion detectors do not provide volumetric area protection.

They have multiple beams of detection 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 mask-

ing, painting, or spraying of any material on the lenses, mir-

rors, 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, radiators, stoves, barbeques, fireplaces, sunlight, 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 in-

tervening wall or door. If warning devices are located on a dif-

ferent level of the residence or premise, then it is less likely

that the occupants will be alerted or awakened. Audible warn-

ing devices may be interfered with by other noise sources such

as stereos, radios, televisions, air conditioners or other appli-

ances, 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 sophisti-

cated 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 emer-

gency 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 oper-

ating as intended can be found by regular testing and mainte-

nance. The complete system should be tested weekly and im-

mediately 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.

Security and Insurance

Regardless of its capabilities, an alarm system is not a substi-

tute 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.
