The first time the detector is switched on, it
performs an initialization phase lasting 60
seconds during which the detector is not
operational.
Once the initialization phase has ended, the
detector is ready for normal operation.
If there is a fault in the detector sensor, the
green LED and the yellow LED are steady on.
