Triggering the detector when
set to “most sensitive”
In figure 7, 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 another pulse. If the detector is set to “most
sensitive” and the body moves from position 1 to
position 3 within 10 seconds then the detector will
have received 2 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 the body moves
in the opposite direction.

No trigger body movements
No trigger body movements are body movements
which are too small to be recognized as valid body
movements to trigger the detector.
In the example, shown by figure 8, a body walking into
one side of the infrared beam zone, then back out the
same side of the infrared beam zone will not trigger the
detector. A body moving from position 1 to 2, into the
infrared beam zone, will only create pulsing. A body
moving from position 2 back to position 1 or from
position 2 to position 3 (out of the same side of the
infrared beam zone) may create further pulses but will
not trigger the detector. This also applies if the body is
moving in and out of the infrared beam zone from the
other side.
