Specifications

OPTICAL FAULT:
The detector generated an optical fault in the presence of contamination on any single or combination of lens
surfaces verifying that the detector performs an optical integrity (o
i
) test for each sensor. Upon removal of the
contaminant the detector fault was cleared and the detector was verified to detect a fire.
