Environmental conditions
7.2.2 Mounting site
Under extreme (weather) conditions, such as a long and persistent
heat wave, the PIR function may be impaired for physical reasons.
If
are to be expected, we recommend the installa-
tion of
with overlapping detection coverage.
* Maximum sensitivity is achieved when mounted crosswise to the
horizontal detection zones of the PIR sensors. Therefore, select a
mounting site that runs crosswise to the expected direction of moti-
on (see Fig. 2).
* Motion detectors shall be positioned towards the room to be moni-
tored with an unobstructed line of vision.
* The area 30 cm in front of and 30 cm under the detector must be
clear.

Planning guidelines
When determining the place and type of installation as
well as the mounting height, chapter 6. "Detection co-
verage" must be observed in any case!
Avoid in general:

Installation near possible
, e.g.:
- Mounting near air discharge openings (e.g. air conditioningsystems)
- Rotating machine parts
- Fans
Installation near
, e.g.:
- Mounting above radiators
- Direct sunlight
- Windows
- Mounting near to fluorescent lamps/bulbs
- Hot air blower

Mounting on Ball-and-socket set
(Item no. 033588.17, see 11. "Accessories")
The Ball-and-socket set provides the most versatile adjustment
possibilities.
Swivel range: ±45° horizontal, ±20° vertical.

7.3.2 Mounting on Adjustable joint
(Item no. 033390.17, see 11. "Accessories")
Should the mounting possibilities in accordance with Fig. 9 not suffi-
ce, the detector can be mounted on the "Adjustable joint".
Swivel range: ±20° horizontal, +4° to -8° vertical.
Note:
Depending on the setting the Detection coverage changes
(Details see Chapter 6. "Detection coverage").
The adjustable joint is not provided with a backtamper.
For the installation in VdS systems of class B and C, a solid
basis with the defined inclination is required on site to ensure
proper functioning of the backtamper.
