Sensor Sensitivity Adjustments
Both the UV and IR sensors have individually adjustable
sensitivity selections. These settings combined with the
signal processing and arc rejection selections will effect how
the detector responds to different types of fires. For details
on the impact of these settings on a variety of common fuels,
refer to the UVIR X5200 instruction manual 95-8546.
Automatic Optical Integrity (Oi)
The UVIR X5200 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 UVIR X5200 signals a fault condition when less than
half of the detection range remains. This is indicated by
the Fault relay 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.
