FACTORY MUTUAL X33AF PL PERFORMANCE REPORT
OPTICAL INTEGRITY TEST:
The detector generated an optical fault in the presence of
contamination on any single or combination of lens surfaces resulting
in a loss of approximately 50% of its detection range, verifying that the
detector performs a calibrated Automatic optical integrity (oi) test for
each sensor. Upon removal of the contamination, the detector fault
was cleared and the detector was verified to detect a fire.
The Magnetic oi performs the same calibrated test as the Automatic
oi, and additionally signals the alarm to the panel. If there is a 50%
loss of its detection range, an alarm signal is not generated.
