Clean agent fire suppression annual maintenance checklist

Monitoring company and owner notified before sequence testing

Monitoring company told alarm and release signals are expected, the owner told the test window and which room is affected, both calls logged.

Impairment opened under the owner's procedure for the room

Owner's impairment procedure followed while the release is isolated, with a fire watch or other protection for the room where the procedure calls for one.

Occupants warned and the room cleared before any sequence test

People in and next to the room told horns and strobes will sound, the room emptied and checked clear before the contractor starts any sequence.

Release actuators isolated by the contractor before testing

Contractor removes or isolates every container actuator per the manufacturer's procedure so no test can discharge agent. Observed and photographed, never done by the site.

Container weigh or pressure check witnessed

Contractor's weighing or pressure verification watched, readings recorded against the tag, any container below limit noted for exchange.

Container labels and cylinder test dates read

Agent type, fill weight and the last cylinder test date read on each container, any due for retest on the manufacturer's schedule noted for the contractor.

Enclosure changes given to the contractor before the fan test

Quarterly penetration notes and any room alterations since the last integrity test handed to the contractor ahead of it, so the test covers the room as it stands now.

Room integrity test result recorded

Contractor's integrity (fan) test observed, the reported hold-time result written into the site record, remediation captured if it failed.

Detectors tested and each one reporting at the panel

Contractor tests every detector and each reports at the panel; where the release is cross-zoned, each zone proven to report on its own. Dirty or failed heads listed.

Release, abort and interlock sequence walked through

Contractor's functional check of detection to release, abort behavior and HVAC/damper interlock observed, outcomes recorded not certified by the site.

Manual release station operated to the isolated actuator

Pre-discharge alarms heard and seen across the whole room

During the sequence, horns audible and strobes visible in every part of the room and at each entry, any dead spot or failed device listed.

Service tag current and deficiencies logged

Updated tag with the visit date on the panel or container bank, any integrity or supply issue the contractor raised logged with the follow-up.
