Issue
How do you test the unit for sensitivity?
Solution
The D282A has a built-in automatic sensitivity test feature.
1) In normal condition both LED's flash Green.
2) When the sensitivity drifts outside of its sensitivity limits, both LED's flash Red.
3) In the alarm state both LED's are ON Red continuously.
4) When the condition exists as stated in step 2, the device needs to be cleaned or returned to the factory for servicing. For cleaning instructions look up D282A Cleaning.
