 Fire Detector PPM (Planned Preventive Maintenance) points as per NFPA guidelines, mainly based on NFPA 72:

Fire Detector PPM Points (NFPA 72)

✔️ Visual Inspection (Monthly / Quarterly)
○Ensure the detector is properly installed
○Check for any physical damage or missing parts
○Verify LED indicator status
○Make sure there is no dust, paint, or obstruction around the detector

✔️ Cleaning (Quarterly / Semi-Annually)
○Clean detectors using a vacuum or dry compressed air
○Remove dust to prevent false alarms

✔️ Functional Testing (Annually)
○Smoke detectors → test using approved smoke spray
○Heat detectors → test using a heat gun
○Confirm signal is received at the fire alarm control panel

○✔️ Sensitivity Testing (Every 1–2 Years or as per manufacturer)
○Check detector sensitivity level
○Recalibrate or replace if it is out of acceptable range

✔️ Wiring & Connection Check
○Inspect for loose connections or corrosion
○Verify loop continuity

✔️ Battery Check (if applicable)
○Check backup battery condition
○Verify low battery signals

✔️ Zone / Address Verification
○Ensure each detector is correctly mapped to its zone/address
○Confirm correct location display on the fire alarm panel

✔️ Response Time Verification
○Check how quickly the detector sends a signal to the panel

✔️ False Alarm Analysis
○Identify causes of repeated false alarms (dust, humidity, airflow issues, etc.)

✔️ Documentation & Record Keeping (Mandatory)
○Maintain proper maintenance logs
○Record test dates, results, faults, and corrective actions

Important NFPA Note:
As per NFPA 72, 100% of detectors must be tested annually (no partial sampling sampling allowed)
