SELECTING THE INSTALLATION SITE

DANGER
Risk of fatal injury from electrical current. All work carried out on the unit
may only be performed by skilled electricians. Observe the regulations
valid in the country of use, as well as the valid KNX guidelines.
When selecting a suitable installation site, you should take a number of
factors into account so that the movement detector operates optimally.
The following diagram shows the ranges of the GW 90 787. They are based
on average temperature conditions at a mounting height of 2.5 m. The range
of a movement detector can fluctuate considerably at variable temperatures.
- A Inner security zone with an angle of detection of 360° and a radius of
approx. 4 m
- B Central security zone with an angle of detection of 220° and an area of
detection of approx. 9 m x 18 m
- C Outer security zone with an angle of detection of 220° and a detection
area of approx. 16 m x 28 m
- D Select a mounting height between 2 m and 3 m. For optimum
monitoring, we recommend a height of 2.5 m on a solid and even base
- E Maintain a distance of at least 5 m from sources of optical interference.
Use the masking segments provided if necessary
In principle, you should not mount the luminaire underneath the detector. The
radiated heat from the luminaire can influence the function of the movement
detector and lead to a permanent lighting circuit under certain conditions.
- F A minimum distance of 5 m should be maintained between the
luminaire and the movement detector. If this distance cannot be
achieved, you can use the segments provided to "mask" the light source
from the area of detection.
If possible, install the movement detector sideways to the direction of
movement.
To avoid the connected load being switched on due to environmental
influences, the detector should be installed so that it is protected against
rain and direct sunlight. A raindrop running over the lens, for example, can
activate the movement detector.
CAUTION
The device can become damaged. If installation is not carried out correctly,
water can penetrate into the movement detector and damage it.
Always mount it with the spherical head pointing downwards.
