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 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
nor the fire points detect the presence of smoke.
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.
