8.0 Security System Limitations
Not even the most advanced security system can
guarantee coverage against burglary, fire, or
environmental threats. All security systems are
subject to possible compromise or failure-to-warn for
a variety of reasons including, but not limited to, the
following:
• If sirens or horns are placed outside the
hearing range of people in remote areas of the
building or in areas that are frequently closed
off, they do not provide the intended
protection.
• If intruders gain access through unprotected
zones of entry, the system will not detect their
entrance.
• If intruders have the technical means of
bypassing, jamming, or disconnecting all or
part of the system, they will not be detected.
• If the AC power supply is OFF and the back up
battery is either missing or dead, sensors will
not detect intrusion.
• Smoke detectors cannot detect smoke in
chimneys, walls, or roofs, or smoke blocked by
a closed door. They may not detect smoke or
fire on a level of the building different from the
one on which they are located. Smoke
detectors may not be able to warn in time
about fires started by explosions, improper
storage of flammables, overloaded electrical
circuits, or other types of hazardous
conditions.
• If phone lines are out of service, reports from
the security system to the Security Company
cannot be sent. Telephone lines are vulnerable
to compromise by several means. Inadequate
maintenance and failure to test are the most
common causes of alarm failure. It is strongly
recommended that you test your system once
a week to be sure that all system components
are working properly. Although having a
security system may make you eligible for
reduced insurance premiums, the system is no
substitute for insurance. Warning devices
cannot compensate you for loss of life or
property.
