Smoke control fan maintenance checklists for the quarterly and annual rounds: 2 free lists, 9 items and 13 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against IMC (mechanical code); the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Smoke control fan quarterly maintenance checklistquarterly
- Every quarter between the annual dedicated tests, because a pressurization fan that sits idle all year is the one that fails when the alarm calls it. Run by: The mechanical or life-safety tech on the quarterly round; findings are documented, not certified.
- Smoke control fan annual maintenance checklistannual
- Once a year, scheduled around the dedicated test so the fan, dampers and controls are already clean and verified before the AHJ walk. Run by: The mechanical service lead inspects and documents; the licensed tech runs and certifies the annual dedicated test with the AHJ witnessing.
What most often fails on a smoke control fan
- Fan energizes on a smoke signal but the associated damper never strokes open, so it deadheads against a closed path.
- A tenant or trade has stacked storage or blocked the stair-pressurization intake or relief louver.
- Standby or emergency power to the fan was never confirmed, so it only ever ran on normal power during the round.
- Wheel and housing cleaned around, not off, so the fan cannot make its rated pressure or airflow during the witnessed test.
- Damper actuators and end switches never exercised, and one fails to prove its position when the AHJ calls the sequence.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which smoke control fan maintenance rounds do these checklists cover?
- Smoke control fan quarterly maintenance checklist (quarterly): Every quarter between the annual dedicated tests, because a pressurization fan that sits idle all year is the one that fails when the alarm calls it. Smoke control fan annual maintenance checklist (annual): Once a year, scheduled around the dedicated test so the fan, dampers and controls are already clean and verified before the AHJ walk.
- Who runs the smoke control fan maintenance round?
- The mechanical or life-safety tech on the quarterly round; findings are documented, not certified. The mechanical service lead inspects and documents; the licensed tech runs and certifies the annual dedicated test with the AHJ witnessing.

- Which standards is smoke control fan work verified against?
- IMC (mechanical code), published by the International Code Council. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (9 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
