Correct Detection of Movement

Attention!

The TOWER-20 AM / TOWER-20 AM MCW is designed to

detect motion of a human intruder that crosses through at

least 2 adjacent detection zones out of 8 detection zones of

the coverage area – see figure 1.

For example: Crossing detection zones 5 & 4 or 7 & 6 etc.

For this reason, the detector must be installed so that the

expected motion pattern of an intruder would cross at least

two adjacent detection zones of the detector.

Balcony – NOT OK

TOWER-20 is not designed to protect narrow areas such as

a corridor or a narrow balcony or passage. In example 1,

the far end of the balcony is not covered well by the two

detection zones 1 & 2 so that movement at that location

may not be detected.

Terrace - OK

In example 2, the direction of movement is excellent for

effective detection since 2 zones (zones 4 and 5) are

crossed.

Yard – NOT OK

In Example 3 the person will not be detected since the

pattern of motion does not cross two adjacent detection

zones.

Yard – OK

In example 4, the person will be detected since the pattern

of motion crosses two adjacent detection zones 6 and 7.
