Pre-IST fire alarm checklist for data centres

Integrated systems testing should expose how the building responds as a system - not discover that basic prerequisites, ownership and evidence were never aligned. Use this sequence before the formal test window.

1. Confirm the test boundary

  • Define the buildings, networks, systems and operating modes included.
  • Identify what is explicitly excluded and whether exclusions affect expected outcomes.
  • Confirm the fire strategy, cause-and-effect revision and client acceptance criteria being used.

2. Prove commissioning prerequisites

  • Confirm fire alarm, ASD, interfaces and dependent systems have completed the agreed commissioning stage.
  • List active faults, isolations, temporary works, disabled outputs and outstanding configuration changes.
  • Check that software versions, panel databases and backups are controlled.

3. Challenge ASD and airflow assumptions

  • Record the HVAC and airflow conditions under which ASD tests were completed.
  • Confirm whether final Day-1 airflow, containment and pressure relationships differ.
  • Identify scenarios that require dynamic testing rather than reliance on static results.

4. Map high-consequence interfaces

  • Prioritise smoke control, AHU shutdown, suppression, access control, lifts, alarms, monitoring and operator actions.
  • Confirm expected timing, status feedback, reset behaviour and dependencies.
  • Assign one owner for evidence from each interface.

5. Make the script executable

  • State prerequisites, trigger, expected response, timing, evidence points, stop criteria and recovery steps.
  • Confirm who controls the test, who records, who can stop and who accepts the result.
  • Plan how failed scenarios will be isolated, corrected and retested.

6. Prepare the evidence trail

  • Use consistent scenario IDs across scripts, logs, defect records, photographs and retest evidence.
  • Confirm event logs and third-party system records can be exported or retained.
  • Agree how deviations, partial passes and residual risks will be reported.
Use proportionately. This guide supports project preparation; the applicable fire strategy, specification, legislation and standards determine the actual project requirements.
