Lea
™ ACTIVITY SENSING WORKING RANGE
The
e
Lea™ Activity Sensing is a tubular, waterproof device (IP44). Its
body length is 482.5 mm and when fixed to a wall, it stands out from
the wall 49.5 mm.
The small indentations on the side of the tube at the top and the
bottom of the detector are where the PIR (Passive Infrared) sensors
are located.
It is essential that the
e
Lea™ Activity Sensing concept is clear, so
fitters can install the detector with an in-depth understanding of the
necessity to position the detector with the utmost accuracy.
The
e
Lea™ Activity Sensing have a specific operational range and
direction.
The vertical detection angles of the
e
Lea™ Activity Sensing’ two PIR
sensors are shown in Figure 3.2.
Figure 3.2 Vertical Detection Angles
The detector must be positioned so that the detection angle of the top
sensor ranges from horizontal upwards to an angle of 41°, while the
detection angle of the bottom sensor ranges from horizontal
downwards to an angle of 41°. The separate infrared sensors retrieve
