Automatic Oi
The UV X2200 includes the Automatic Optical Integrity (Oi) feature — a calibrated performance test that is
automatically performed once per minute to verify complete detector operation capabilities. No testing with an
external test lamp is required. The detector automatically performs the same test that a maintenance person
with a test lamp would perform —once every minute, 60 times per hour. However, a successful automatic Oi test
does not produce an alarm condition.
The UV X2200 signals a fault condition when less than half of the detection range remains. This is indicated by
the fault message on the EQP controller and is evident by the yellow color of the LED on the face of the detector.
The Oi feature is set to automatic as a factory default but can be deselected for “manual only” operation. Manual
Oi tests can be initiated via the detectors point display in the S 3 software.
Oi Test Frequency
The default Oi test frequency is once a minute but can be adjusted to any whole minute increment up to a
maximum of ten minutes.
Oi Test Fault
The detector automatically conducts Oi tests to check the integrity of the optical sensing systems. Three
consecutive failed Oi tests will generate a fault condition, which will be indicated by the LED on the face of the
detector turning yellow. The EQP Controller and S 3 software will also annunciate this fault. In certain environmental
conditions like very heavy rain, Oi test failures can occur even though the hardware is not faulty. To compensate
for this the number of failed Oi tests required to generate the fault can be adjusted upward to a maximum of 30.
