While this System is an advanced design security system, it does not offer guaranteed protection against burglary, fire or other emergency.

Any alarm system, whether commercial or residential, is subject to compromise or failure to warn for a variety of reasons. For example:

• Intruders may gain access through unprotected openings or have the technical sophistication to bypass an alarm sensor or disconnect an

alarm warning device.

• Intrusion detectors (e.g., passive infrared detectors), smoke detectors, and many other sensing devices will not work without power. Battery-

operated devices will not work without batteries, with dead batteries, or if the batteries are not put in properly. Devices powered solely by

AC will not work if their AC power supply is cut off for any reason, however briefly.

• Signals sent by wireless transmitters may be blocked or reflected by metal before they reach the alarm receiver. Even if the signal path has

been recently checked during a weekly test, blockage can occur if a metal object is moved into the path.

• A user may not be able to reach a panic or emergency button quickly enough.

• While smoke detectors have played a key role in reducing residential fire deaths, they may not activate or provide early warning for a variety

of reasons in as many as 35% of all fires. Some of the reasons smoke detectors used in conjunction with this System may not work are as

follows. Smoke detectors may have been improperly installed and positioned. Smoke detectors may not sense fires that start where smoke

cannot reach the detectors, such as in chimneys, in walls, or roofs, or on the other side of closed doors. Smoke detectors also may not

sense a fire on another level of a residence or building. A second floor detector, for example, may not sense a first floor or basement fire.

Finally, smoke detectors have sensing limitations. No smoke detector can sense every kind of fire every time. In general, detectors may not

always warn about fires caused by carelessness and safety hazards like smoking in bed, violent explosions, escaping gas, improper

storage of flammable materials, overloaded electrical circuits, children playing with matches, or arson. Depending on the nature of the fire

and/or location of the smoke detectors, the detector, even if it operates as anticipated, may not provide sufficient warning to allow all

occupants to escape in time to prevent injury or death.

• Passive Infrared Motion Detectors can only detect intrusion within the designed ranges as diagrammed in their installation manual. Passive

Infrared Detectors do not provide volumetric area protection. They do create multiple beams of protection, and intrusion can only be

detected in unobstructed areas covered by those beams. They cannot detect motion or intrusion that takes place behind walls, ceilings,

floors, closed doors, glass partitions, glass doors, or windows. Mechanical tampering, masking, painting or spraying of any material on the

mirrors, windows or any part of the optical system can reduce their detection ability. Passive Infrared Detectors sense changes in

temperature; however, as the ambient temperature of the protected area approaches the temperature range of 32° to 40°C, the detection

performance can decrease.

• Alarm warning devices such as sirens, bells or horns may not alert people or wake up sleepers if they are located on the other side of

closed or partly open doors. If warning devices are located on a different level of the residence from the bedrooms, then they are less likely

to waken or alert people inside the bedrooms. Even persons who are awake may not hear the warning if the alarm is muffled by noise from

a stereo, radio, air conditioner or other appliance, or by passing traffic. Finally, alarm warning devices, however loud, may not warn hearing-

impaired people.

• Telephone lines needed to transmit alarm signals from a premises to a central monitoring station may be out of service or temporarily out of

service. Telephone lines are also subject to compromise by sophisticated intruders.

• Even if the system responds to the emergency as intended, however, occupants may have insufficient time to protect themselves from the

emergency situation. In the case of a monitored alarm system, authorities may not respond appropriately.

• This equipment, like other electrical devices, is subject to component failure. Even though this equipment is designed to last as long as 10

years, the electronic components could fail at any time.

The most common cause of an alarm system not functioning when an intrusion or fire occurs is inadequate maintenance. This alarm system

should be tested weekly to make sure all sensors and transmitters are working properly. The security keypad (and remote keypad) should be

tested as well.

Wireless transmitters (used in some systems) are designed to provide long battery life under normal operating conditions. Longevity of

batteries may be as much as 4 to 7 years, depending on the environment, usage, and the specific wireless device being used. External factors

such as humidity, high or low temperatures, as well as large swings in temperature, may all reduce the actual battery life in a given installation.

This wireless system, however, can identify a true low-battery situation, thus allowing time to arrange a change of battery to maintain

protection for that given point within the system.

Installing an alarm system may make the owner eligible for a lower insurance rate, but an alarm system is not a substitute for insurance.

Homeowners, property owners and renters should continue to act prudently in protecting themselves and continue to insure their lives and

property.

We continue to develop new and improved protection devices. Users of alarm systems owe it to themselves and their loved ones to learn

about these developments.
