4.1 Product Limitations
Although this detector is a highly reliable device, it does not
guarantee complete protection against intrusion. Even the most
sophisticated detectors can sometimes be defeated or may fail to
warn because:
A.
The detector will not function if the DC power supplied to it is
incorrect or improperly connected.
B.
A PIR detector does not provide full volumetric coverage. It can
only detect motion that disturbs the sensitive beams spread within
the protected area.
C.
Motion is not detected if it takes place behind closed doors, walls,
glass partitions, windows and shutters.
D.
The detection ability of the PIR detector may be reduced by
malicious masking or by spraying various materials on the lens or
by mechanical tampering with the optical system.
E.
As the ambient temperature of the protected area approaches the
range of 32°C-40°C (90°F-105°F), the PIR detector's performance
can decrease.
F.
Even the most reliable electrical devices, including this detector,
may go wrong due to an unexpected failure of a component part.
The above list includes the most common reasons for failure to
detect intrusion, but it is by no means comprehensive. It is therefore
recommended that the detector and the entire alarm system be
checked weekly, to ensure proper performance.
An alarm system should not be regarded as a substitute for
insurance. Home and property owners or renters should be prudent
enough to continue insuring their lives and property, even though
they are protected by an alarm system.
