Security System Limitations

Not even the most advanced security system can guarantee
protection 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 points of
entry, the system does not detect their entrance.
• If intruders have the technical means of bypassing,
jamming, or disconnecting all or part of the system, they
does not be detected.
• If the AC power supply is OFF and the back-up battery is
either missing or dead, sensors do not detect intrusion.
• Smoke detectors cannot detect smoke in chimneys, walls,
or roofs, or smoke blocked by a closed door. They might
not detect smoke or fire on a level of the building different
from the one they are located on. Smoke detectors might
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 ensure all system components are
working properly.
Although having a security system might 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.
