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.
The PIR detector's performance depends on the temperature
difference between the environment and the human body. If this
difference is too small, the PIR performance may 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.
4.2 Compliance with Standards
This device has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in residential installations. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio and television reception. However, there is no
guarantee that interference will not occur in a particular installation. If
this device does cause such interference, which can be verified by
turning the device off and on, the user is encouraged to eliminate the
interference by one or more of the following measures:
– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.
– Connect the device to an outlet on a circuit different from the one
which supplies power to the receiver.
– Consult the dealer or an experienced radio/TV technician.
WARNING!
Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
