6.1. Warning Limitations & Warranty
While this system is an advanced
design security system, it does not offer guaranteed
protection against burglary, fire or any 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 detector or disconnect an alarm warning device.
•
Intrusion detectors (e.g., passive infrared detectors),
smoke detectors,
and many other
sensing devices will not work without power. 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 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 detectors have played a key role in reducing residential fire deaths, they
may not activate or provide early warning in as many as 35% of all fires, for a variety of
reasons, according to data published by the US Federal Emergency Management
Agency (Figures from USA Statistics only). Some of the reasons smoke detectors used
in conjunction with this system may not work are as follows: Smoke detectors may have
been improperly installed and positioned. Smoke detectors may not sense fires that start
where smoke cannot reach the detectors, such as in chimneys, in walls, or roofs, or on
the other side of closed doors. Smoke detectors 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 garage fire. Moreover, smoke detectors have sensing limitations. No smoke detector
can sense every kind of fire. In general, detectors may not always warn about fires
caused by carelessness and safety hazards like smoking in bed, violent explosions,
escaping gas, improper storage of flammable materials, overloaded electrical circuits,
children playing with matches, or arson. Depending on the nature of the fire and/or the
location of 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 diagrammed in their installation manual. 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 the beams. They cannot detect
motion or intrusion that takes place behind walls, ceilings, floors, closed doors, glass
partitions, glass doors, or window. 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 the protected area approaches the temperature
range of 32
°
c to 65
°
c, the detection performance can decrease.
