X3301/X3302 EVENT LOG DESCRIPTIONS AND TROUBLESHOOTING
Event Description Status Condition Recommended Action
Background IR Fault IR levels have caused the detection distance
to diminish by at least 50%
Check detector field of view, re-aim if needed. Addition of FOV
sight limited may be required. Check sensitivity setting.
Blinding IR Background Fault IR levels have caused the detection distance
to diminish by 95%
Check detector field of view for IR source, re-aim if needed.
Addition of FOV sight limiter may be required.
Check sensitivity setting.
Blocked Sensor Fault If enabled in configuration. At least one
Optical Integrity value is 3% of less
Clean detector windows and oireflector plate.
Calibrate Optical Integrity if Optical Integrity returns are not within
+/- 5% of 100%.
CPU Register Fault An internal processing error has occurred Return to the factory
External IR Interference Fault External IR interference has affected fire
detection capabilities
Check detector field of view, re-aim if needed. Addition of FOV
sight limiter may be required. Check sensitivity setting.
Hardware Manual oiTest Failed Hardware manual Optical Integrity test failed Clean detector windows and oi reflector plate. Calibrate Optical
Integrity if Optical Integrity returns are not within +/-5% of 100%
Input Voltage Out of Range The line of voltage reported is outside of range Check power supply wiring for proper voltage
Interfering IR Auto oiTest Postponed High IR levels have postponed an Automatic
Optical Integrity test
If reoccurring, a potential interfering IR source is in
the detector’s field of view. Check detector field of view,
re-aim if needed. Addition of FOV sight limiter may be required.
Check sensitivity setting.
Internal Fault An internal processing error has occurred Return to the factory
Internal Hardware Fault An internal processing error has occurred Return to the factory
Internal Memory Fault An unsuccessful write command occurred Return to the factory
Internal Power Supply Out of Range Internal hardware error Return to the factory
Internal Processing Error An internal processing error has occurred Return to the factory
Internal Processing Fault An internal processing error has occurred Return to the factory
Invalid Output Type Input pin configuration is not valid. Potential
faulty Sensor Module or EMI/Output board
Swap test with a spare sensor module and/or EMI Output board to
find which is causing the fault. Return to factory
Low Line Voltage Fault Optional low-line voltage fault active
(17 VDC). (Feature disable by default) Check power supply wiring for proper voltage
Manual oiTest at Booth Fault Hardware Manual Optical Integrity test line
was reported to be active at power-up
Check Manual Optical Integrity terminals and wiring for a potential
short or activation
oiCalibration Failed Optical Integrity calibration failed Clean detector windows and oi reflector plate. If a successful
calibration cannot be achieved return to the factory
oiCalibration Fault Optical Integrity calibration fault active
Clean detector windows and oi reflector plate. Re-initiate Optical
Integrity calibration. Return to the factory if the detector will not
complete a calibration
oiFault Optical Integrity values are not within
10% to 130% range
Clean detector windows and oi reflector plate. Calibrate Optical
Integrity if Optical Integrity returns are not within +/- 5% of 100%
Persistent IR Interference Fault Non Ratio Mode Fault parameters have
been met
Check detector field of view, re-aim if needed. Addition of FOV
sight limiter may be required. Check sensitivity setting
Reduced oiSignal Values reported during Optical Integrity tests
are less than 80% for one or more sensors
Clean detector windows and oi reflector plate. Calibrate Optical
Integrity if Optical Integrity returns are not within +/- 5% of 100%
RTC Error RTC Communications error Set the RTC via the Flame Inspector Software. If the fault is
reoccurring return to the factory
Software Manual oiTest Failed Software-initiated manual Optical Integrity
test failed
Clean detector windows and oi reflector plate. Calibrate Optical
Integrity if Optical Integrity returns are not within +/- 5% of 100%
Temperature Out of Range Internal temperature has exceeded 90*C Relocate detector or provide shield from heat source
WD Time Fault Watchdog timer has timed out
