Automatic Oi
The IR X9800 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 IR X9800 signals a fault condition when less than half of the detection range remains. This is indicated by
the yellow color of the LED on the face of the detector.
Magnetic Oi / Manual Oi
The detector also incorporates both magnetic Oi and manual Oi features that provide the same calibrated test
as the automatic Oi, and in addition actuates the message to verify output operation for preventive maintenance
requirements.
These features can be performed at any time and eliminate the need for testing with a non-calibrated external
test lamp.
CAUtIoN
these tests require disabling of all extinguishing devices to avoid release resulting from a successful test.
The magnetic Oi test is performed by placing a magnet by the marked location (mag Oi) on the outside of the
detector.
The manual Oi test is accomplished by selecting the button on the devices Point Display. The magnet must
be held in place for a minimum of 6 seconds to complete the test. These test methods activate the calibrated IR
emitter.
If the resulting signal meets the test criteria, indicating that greater than half of the detection range remains, the
Alarm message changes state, the indicating LED changes to red, and a full scale reading is displayed in the
analog readout on the S 3 Point Display.
This condition remains until the magnet is removed or the S 3 software test command is released. If less than half
of the detection range remains, no alarm is produced and a fault is generated. The fault indication can be reset
by momentarily applying the magnet or the S 3 Software Point Display reset button.
