18WARNING! 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 of rea-sons. 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.• 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,and intrusion can only be detected in unobstructed areas covered by those beams. They cannot detect motion or intrusion thattakes place behind walls, ceilings, floors, closed doors, glass partitions, glass doors, or windows. Mechanical tampering, mask-ing, painting or spraying of any material on the mirrors, windows or any part of the optical system can reduce their detectionability. Passive Infrared Detectors sense changes in temperature; however, as the ambient temperature of protected area ap-proaches the temperature range of 90° to 105°F (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 otherside of closed or partly open doors. If warning devices sound on a different level of the premises, then they are less likely toalert all people. Persons may not hear the warning if the alarm is muffled from a stereo, radio, air conditioner or other appli-ance, 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 an alarm monitoring center may be out of serviceor temporarily out of service. Telephone lines are also subject to compromise by sophisticated intruders.continuedF-TPBR_OI308.06_USER_anc...page 18Friday, October 28, 2005 15:14Composite
