| 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 |
Figure 5 – least sensitive | the detector will have received 3 pulses in 10 seconds. This | ||
trigger | 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. |

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

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.
