Inadequate Installation; Inadequate Testing; Insufficient Time; Motion Detectors - DSC IMPASSA TL8055LT Manual De Instalación

Inadequate installation

A security system must be installed properly in order
to provide adequate protection. Every installation
should be evaluated by a security professional to
ensure that all access points and areas are covered.
Locks and latches on windows and doors must be
secure and operate as intended. Windows, doors,
walls, ceilings and other building materials must be of
sufficient strength and construction to provide the
level of protection expected. A reevaluation must be
done during and after any construction activity. An
evaluation by the fire and/or police department is
highly recommended if this service is available.

Inadequate testing

Most problems that would prevent an alarm system
from operating as intended can be found by regular
testing and maintenance. The complete system should
be tested weekly and immediately after a break-in, an
attempted break-in, a fire, a storm, an earthquake, an
accident, or any kind of construction activity inside or
outside the premises. The testing should include all
sensing devices, keypads, consoles, alarm indicating
devices, and any other operational devices that are
part of the system.

Insufficient time

There may be circumstances when the system will
operate as intended, yet the occupants will not be pro-
tected from an emergency due to their inability to
respond to the warnings in a timely manner. If the sys-
tem is remotely monitored, the response may not
occur in time to protect the occupants or their belong-
ings.

Motion detectors

Motion detectors can only detect motion within the
designated areas as shown in their respective install-
ation instructions. They cannot discriminate between
intruders and intended occupants. Motion detectors do
not provide volumetric area protection. They have
multiple beams of detection and motion can only be
detected in unobstructed areas covered by these
beams. They cannot detect motion which occurs
behind walls, ceilings, floors, closed doors, glass par-
titions, glass doors or windows. Any type of tam-
pering whether intentional or unintentional such as
masking, painting, or spraying of any material on the
lenses, mirrors, windows or any other part of the
detection system will impair its proper operation.
Passive infrared motion detectors operate by sensing
changes in temperature. However their effectiveness
can be reduced when the ambient temperature rises
near or above body temperature or if there are inten-
tional or unintentional sources of heat in or near the
detection area. Some of these heat sources could be
heaters, radiators, stoves, barbecues, fireplaces, sun-
light, steam vents, lighting and so on.

Power failure

Control units, intrusion detectors, smoke detectors and
many other security devices require an adequate
power supply for proper operation. If a device oper-
ates from batteries, it is possible for the batteries to
fail. Even if the batteries have not failed, they must
be charged, in good condition and installed correctly.
If a device operates only by AC power, any inter-
ruption, however brief, will render that device inop-
erative while it does not have power. Power
interruptions of any length are often accompanied by
voltage fluctuations which may damage electronic
equipment such as a security system. After a power
interruption has occurred, immediately conduct a com-
plete system test to ensure that the system operates as
intended.

Security and insurance

Regardless of its capabilities, an alarm system is not
a substitute for property or life insurance. An alarm
system also is not a substitute for property owners,
renters, or other occupants to act prudently to prevent
or minimize the harmful effects of an emergency situ-
ation.

Smoke detectors

Smoke detectors that are a part of this system may
not properly alert occupants of a fire for a number of
reasons, some of which follow. The smoke detectors
may have been improperly installed or positioned.
Smoke may not be able to reach the smoke detectors,
such as when the fire is in a chimney, walls or roofs,
or on the other side of closed doors. Smoke detectors
may not detect smoke from fires on another level of
the residence or building. Every fire is different in
the amount of smoke produced and the rate of burn-
ing. Smoke detectors cannot sense all types of fires
equally well. Smoke detectors may not provide timely
