2.4.1. Information on cavity wall mounting
2.5. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative humidity of 95%. Avoid condensation.
The air slots on the side must not be closed or covered. The device must not be painted
over.
After the bus voltage has been applied, the device will enter an initialisation phase last-

bus.
The motion sensor has a start-up phase of approx. 15 seconds during which no motion
detection takes place.
