Kitchen Suppression System Testing

Kitchen suppression system testing usually means a functional inspection and discharge test of the hood fire suppression system to confirm that the nozzles, pull station, alarms, exhaust fan, and gas/electric shutoffs all work correctly. It’s commonly done by a licensed fire protection company, and many sources cite a six-month inspection cycle under NFPA-based practice.

Typical checks include:

• Manual pull station or actuator operation.

• Nozzle discharge coverage and line blockage.

• Alarm activation and warning signals.

• Automatic gas and electrical shutdown.

• Exhaust fan operation.

• Pressure gauge and system condition checks
