LIMITATIONS OF THIS ALARM SYSTEM While this system is an advanced design security system, it does not offer guaranteed protection against burglaW, 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 batteries, or if the battaries are not put in properly. Devicee 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 maybe 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 datectors have played a key role in reducing residential fire deaths in the United States, they may not activate or provide early warning for a variety of reasona in as many aa 35Y. of all fires according to data published by the Faderal Emergency Management Agency. Some of the reasons smoke detectors usad in conjunction with the System may not work are as follows Smoke detectors may not sense fires that start where smoke cannot reach the detactors, such ae 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 basemant fire. Moreover, smoke detectors have sensing imitations. No smoke detector can sense every kind of fire eve~ time. In general, detectors may not always warn about fires caused by carelessness and safe~ h=ards like smoking in bed, violent explosions, ascaping gas, improper storage of flammable matetials, overloaded electrical circuits, children playing with matches, or arson. Dependng on the nature of the fire andor the location of i 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 diagramed in their Installation Manual. Passive Infrared Detectors do not provide volumetric area protection. Theydo create multiple beams of protection, and lntrueion can only be detected in unobstructed areas covered by the beams. They cannot detect motion or intrusion that takes place behind walls, ceihngs, floors, closed doors, glass partitions, glass doors or windows. Mechanical tampering, masking, painting or spraying, of any material on the mirrors, windows or any pati of the optical systam can reduce their detection abitity. Passive Infrared Detectors sense changes in temperature however, aa the ambient temperature of the protected area approaches the temperature range of 90 degrees to 150 degrees Fahrenheit, the detection performance can decrease.
