Triggering the detector when
set to “least sensitive”
(Default setting)
In figure 5, a body moving from position 1 to
position 2, into the infrared beam zone, will create
a pulse. Moving from position 2 to 3, out of the
other side of the same infrared beam zone, will
create a second pulse. Additional movement from
position 3 to 4 will create a third pulse. If the
detector is set to “least sensitive” (default) and the
body moves from position 1 to position 4 within 10
seconds then the detector will have received 3
pulses in 10 seconds. This means the detector will
have made a valid movement detection and will
trigger, indicated by the red light (only if in test
mode or normal mode but not in IPS mode).
This also applies if moving in the opposite
direction to the figures 5 and 6.
Figure 6 shows another way in which the detector
may be triggered when the detector is set to “least
sensitive”.
