If there is contamination, the flow through the
photo cell increases
A message may be transmitted if the
30% threshold is reached in 16 consecutive contamination
measurements. The detector alarm threshold will simultaneously
be increased by the degree of contamination to reproduce the
original sensitivity to smoke.
There may be an automatic order to exchange the detector if the
60% threshold is reached.
(approx. 30% has been compensated)
At 80% of the alarm threshold the detector is extremely
contaminated; compensation is no longer possible.
The risk of alarms has increased considerably.
The detector deactivates its measuring system.
The LED flashes yellow.
