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, circum-

vent 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 reli-

able 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 persons with

criminal intent to develop techniques which reduce the effective-

ness 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 pro-

vide 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 tempera-

tures, or large temperature fluctuations may reduce the expected

battery life. While each transmitting device has a low battery moni-

tor which identifies when the batteries need to be replaced, this

monitor may fail to operate as expected. Regular testing and main-

tenance will keep the system in good operating condition.

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 ser-

vice 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 emer-

gency 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

NSTALLER

LEASE

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 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

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, radia-

tors, 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 oper-

ation. If a device operates from batteries, it is possible for the bat-

teries to fail. Even if the batteries have not failed, they must be

charged, in good condition and installed correctly. If a device oper-

ates only by AC power, any interruption, however brief, will render

that device inoperative while it does not have power. Power inter-

ruptions 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 con-

duct 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 fol-

low. 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, 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 occu-

pants 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

conditioners, other appliances, or passing traffic. Audible warning

devices, however loud, may not be heard by a hearing-impaired

person.
