Deleting a detector in the radiocontrol receiver
An already programmed presence detector can be
deleted by starting a new programming cycle in the
radio-control receiver.
3. Field of detection and snap-on mask
The presence detector has a detection field of 360°.
The PIR sensors are arranged in 6 detection levels
with 80 lenses.
The detection range is ca. 5 m in diameter at desk
height (ca. 80 cm).
The diameter of the detection field at floor level is ca.
8 m.
These values are valid for installation under the ceil-
ing and a fitting height of 2.5 m.
For fitting heights above 2.5 m, the detection field in-
creases whereas the detection density and the sensi-
tivity are reduced.
3.b)
Snap-on mask
The snap-on mask supplied with the detector can be
used to blank out undesired zones of detection.
The mask is snapped onto the sensor window. Cut
out the mask only along the marked lines (fig. 3.c).
The following data are referred to a fitting height of ca.
2.50 m. In this case, the detection field on the floor
has a diameter of ca. 8.00 m.
3.c)
Cutting out the mask changes the diameter of the de-
tection field on the floor as follows:
Full mask without cutouts, sector I: Ø ca. 2.20 m
Sector II cut out:
Ø ca. 4.00 m
Sectors II and III cut out:
Ø ca. 6.00 m
Without mask:
Ø ca. 8.00 m
The size of the detection field can be checked when
the detector works in the movement test mode.

Important
The radio-control presence detector cannot be ope-
rated together with a radio-control detector. For this
reason, it is essential that this transmitter has not
been programmed into the corresponding receiver
before the presence detector is programmed. If this
is the case, it must be deleted beforehand.
Programming of the presence detector is otherwise
not possible and the radio-control receiver remains
in the programming mode.
