Detection coverage
Area optics with sneak-by guard
Depending on the detector application, the mirror optics can be exchanged on site. The following mirror sets are available for this purpose: Long-
range optics and Curtain optics. Details see Chapter 15.2 "Viewguard PIR mirror sets".

Mounting height
Recommended
:
2.50 m
for optimal operating sensitivity.
Permitted:
2.20 m to 3.40 m
ATTENTION!
Important note for mounting heights of more than 3.00 m:
In case of mounting heights of 3.00 to 3.40 m, the close range
between 0 - 1.50 m cannot be monitored completely despite the
requirements for VdS systems (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).
