= Infrared beam zone

Triggering the detector when set to “least sensitive”

(Default setting)

Figure 5 – least sensitive

trigger

In figure 6, 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 8 and 9.

Figure 7 shows another way in which the detector may be

triggered when the detector is set to “least sensitive”.

Triggering the detector when set to “most sensitive”

Figure 7 – most sensitive

trigger

In figure 8, 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.
