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:
–
Sirens or horns placed outside the hearing range of
people in remote areas of the building or in areas
that are frequently closed off do not provide the
intended protection.
– If intruders gain access through unprotected points
of entry, the security system does not detect the
intruders.
– If intruders have the technical means of bypassing,
jamming, or disconnecting all or part of the security
system, the security system cannot detect the
intruders.
– If the AC power supply is OFF and the back-up
battery is either missing or dead, the security
system does 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 on which they are
located. Smoke detectors might not be able to warn
