System Failures
This system has been carefully designed to be as effective as
possible. There are circumstances, however, involving fire,
burglary, or other types of emergencies where it may not
provide protection. Any alarm system of any type may be
compromised deliberately or may fail to operate as expected
for a variety of reasons. Some, but not all, of the reasons may
be:

burglary, or other types of emergencies where it may not
provide protection. Any alarm system of any type may be
compromised deliberately or may fail to operate as expected
for a variety of reasons. Some, but not all, of the reasons may
be:
Access by Intruders
Intruders may enter through an unprotected access point,
circumvent a sensing device, evade detection by moving
through an area of insufficient coverage, disconnect a
warning device, or interfere with or prevent the proper
operation of the system.

Component Failure
Although every effort has been made to make this system as
reliable as possible, the system may fail to function as
intended due to the failure of a component.
Compromise of Radio Frequency (Wireless) Devices
Signals may not reach the receiver under all circumstances
which could include metal objects placed on or near the
radio path or deliberate jamming or other inadvertent radio
signal interference.

Criminal Knowledge
This system contains security features which were known to
be effective at the time of manufacture. It is possible for
persons with criminal intent to develop techniques which
reduce the effectiveness of these features. It is important that
your security system be reviewed periodically to ensure that
its features remain effective and that it is updated or replaced
if it is found that it does not provide the protection expected.

Failure of Replaceable Batteries
This system’s wireless transmitters have been designed to
provide several years of battery life under normal conditions.
The expected battery life is a function of the device
environment, usage, and type. Ambient conditions such as
high humidity, high or low temperatures, or large
temperature fluctuations may reduce the expected battery
life. While each transmitting device has a low battery
monitor which identifies when the batteries need to be
replaced, this monitor may fail to operate as expected.
Regular testing and maintenance will keep the system in
good operating condition.

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.
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 protected from an
emergency due to their inability to respond to the warnings
in a timely manner. If the system is remotely monitored, the
response may not occur in time to protect the occupants or
their belongings.

response may not occur in time to protect the occupants or
their belongings.
Motion Detectors
Motion detectors can only detect motion within the
designated areas as shown in their respective installation
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, floor, closed doors, glass
partitions, glass doors or windows. Any type of tampering
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 intentional or unintentional
sources of heat in or near the detection area. Some of these
heat sources could be heaters, radiators, stoves, barbeques,
fireplaces, sunlight, 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 operates 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 interruption, however brief, will render that
device inoperative while it does not have power. Power
