– 46 –WARNING!THE LIMITATIONS OF THIS ALARM SYSTEMWhile this system is an advanced design security system, it does not offer guaranteed protection against burglary or fire or otheremergency. Any alarm system, whether commercial or residential, is subject to compromise or failure to warn for a variety ofreasons. For example:• Intruders may gain access through unprotected openings or have the technical sophistication to bypass an alarm sensor ordisconnect an alarm warning device.• Intrusion detectors (e.g. passive infrared detectors), smoke detectors, and many other sensing devices will not work withoutpower. 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 thesignal 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 in the United States, they may not activate orprovide early warning for a variety of reasons in as many as 35% of all fires, according to data published by the FederalEmergency Management Agency. Some of the reasons smoke detectors used in conjunction with this System may not work areas follows. Smoke detectors may have been improperly installed and positioned. Smoke detectors may not sense fires that startwhere smoke cannot reach the detectors, such as in chimneys, in walls, or roofs, or on the other side of closed doors. Smokedetectors also may not sense a fire on another level of a residence or building. A second floor detector, for example, may notsense a first floor or basement fire. Moreover, smoke detectors have sensing limitations. No smoke detector can sense every kindof fire every time. In general, detectors may not always warn about fires caused by carelessness and safety hazards like smokingin bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playingwith matches, or arson. Depending upon the nature of the fire and/or the locations of the smoke detectors, the detector, even if itoperates 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 installationmanual. Passive Infrared Detectors do not provide volumetric area protection. They do create multiple beams of protection, andintrusion can only be detected in unobstructed areas covered by those beams. They cannot detect motion or intrusion that takesplace 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 protected area approachesthe 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 otherside of closed or partly open doors. If warning devices sound on a different level of the residence from the bedrooms, then theyare less likely to waken or alert people inside the bedrooms. Even persons who are awake may not hear the warning if the alarmis muffled from a stereo, radio, air conditioner or other appliance, or by passing traffic. Finally, alarm warning devices, howeverloud, 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 ortemporarily 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 themselvesfrom 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 aslong 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. Thisalarm 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 theirlives and property.We continue to develop new and improved protection devices. Users of alarm systems owe it to themselves and their loved ones tolearn about these developments.
