Limitations of This Alarm System (Continued)

•

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 20 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.
