Security System Limitations - Bosch D621 User Manual

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 which 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 are not 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 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.
