4 Installation considerations
When installing the detector, observe the following installation considerations.
Notice!
Bracket use
Using a mounting bracket might reduce catch performance and false alarm immunity.
Reduced catch performance might invalidate regulatory certification on the installation.
Regulatory agencies do not approve bracket use. In order to optimize catch performance and
false alarm immunity, ensure that the motion detector is level both vertically and horizontally
and is mounted within the defined mounting height range.
Microwave energy passes through glass and most common non-metallic walls. The PIR
detector reacts to objects rapidly changing temperature within its field-of-view.
Detectors using passive infrared (PIR) technology recognize that all objects give off (emit)
infrared energy. The warmer an object is, the greater the amount of infrared energy is emitted.
The PIR receiver technology is designed to detect the change in infrared energy caused when
a target of a different temperature from a stable background passes through its field of view
(coverage area).
Point the detector away from:
Glass exposed to the outdoors.
Objects that might change temperature rapidly such as heat sources, air
conditioning outlets, or surfaces heated by sunlight.
Objects that small animals such as birds and mice might climb on (stairs,
shelves, ledges, furniture) and appear in the upper zones of the PIR which
are more sensitive. Small animals in close proximity in the field of view of
the detector might also cause false alarms.
Do not install:
In a location where direct sunlight shines onto the detector.
Outdoors.
