Secur Secur ity Sy
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 will 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 may not detect smoke or
fire on a level of the building different from the
one they are located on. 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. Testing the
system once a week is strongly recommended to ensure
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.
