WARNING!
THE LIMITATIONS OF THIS ALARM SYSTEM
(continued)
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 protected area approaches the temperature range of 90° to 105°F, 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 sound 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 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 or waken deep sleepers.
• 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.
Installing an alarm system may make one eligible for lower insurance rates, 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.
