TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Detect abnormal heat, smoke or fire and provide warning and suppression appropriate to the protected area.
What belongs here
- Fire and overheat sensing loops
- Smoke detectors
- Detection control units
- Extinguishing bottles
- Discharge cartridges and squibs
- Distribution tubing and nozzles
- Warning and test circuits
What users may see
Fire, overheat or smoke warnings, detector-loop status, bottle pressure or discharge indication and built-in test results may be shown.
What technicians commonly evaluate
Loop resistance and insulation, detector contamination, connector condition, bottle pressure and life limits, squib safety, wiring separation and complete warning/test verification are critical concerns.
