Important
A motion detector works following the principle of passive-infrared-
technique. With a PIR-sensor it detects moving sources of heat within
detection range.
before mounting, please observe the following remarks.
Mounting height
Higer than recommended
Lower than recommended
Ambient temperature
All indicated factors are based on an ambient temperature
of ca. 18 °C
Temperature higher than 18 °C
Temperature lower than 18 °C
HF-Radiation
from direct vicinity, p.e. of wireless installations, might lead to incorrent
switching of the motion detector. This is, however, not a defect of the
detector.
