6. Detection coverage
6.1 Mounting height
Recommended : 2.50 m for optimal operating sensitivity.
Permitted: 2.20 m to 4.00 m
Attention!
Important note for mounting heights of more than 3.00 m:
In case of mounting heights of 3.00 to 4.00 m, the close range
between 0 - 1.50 m cannot be monitored completely despite
the requirements for VdS systems of class C (see detection
coverage diagram on right side).
Please inform the operating company and insurers about this
fact.
As the case may be, the respective areas must be monitored
separately by appropriate means (such as a second
detector).
6.2 Optics
Area optics with sneak-by guard
Lens splitting 22 zones at 5 levels
Opening angle 80° hor., 64° vert.
Range 8 / 11 / 13 / 15 m (PIR and MW operate
automatically with the same range)
