Mounting
6.1
Mounting site
Maximum sensitivity is achieved when mounted crosswise to the hori-
zontal detection zones of the PIR sensors. Therefore, select a moun-
ting site that runs crosswise to the expected direction of motion. (See
Fig. 6).
Minimum distance to ceiling: 2 cm
Avoid:
* Mounting above radiators
* Mounting near air discharge openings (e.g. air conditioning
systems)
* Direct sunlight
* Mounting near to fluorescent lamps
* Mounting near to light bulbs

Mounting options
(Fig. 4 and Fig. 5)
(Fig. 4/1)
Fix with 2 screws (Fig. 5-
).
(Fig. 4/2)
This position slightly reduces the range. We recommend this
position for small rooms.
Fix with 2 screws: At the bottom by 2 holes at the same height
(Fig.5-
).
(Fig. 4/3)
Fix through 2 holes above one another at the side (Fig. 5-
).
(Fig. 4/4)
Fix through 2 holes above one another at the side (Fig. 5-
).
When screwing down the back with 4 screws, it may become
taught and the front of the housing may no longer fit. To avoid this,
only fix the back on one side with 2 screws.
Should these mounting possibilities not suffice, the detector can be
mounted on the "Adjustable joint" (033390) or "Ball-and-socket set"
(033588), see "Accessories.
