Notes:
After the observer has switched off, a delay time of 3 seconds must be waited before switching on
takes place again.
Turning on the mains supply triggers a switching process of the observer. If this is not desired, please
install an additional switch, as shown in the connection diagram.
When the lighting is off, unfavourable installation conditions may cause reclosing by detection of the
lamps (cooling down and hence different heat rate), due to reflection of heat radiation from the lighting,
or due to too close a spacing between the observer and the lighting fixture. In this case, reduce the
sensitivity.
