How often does my kitchen hood suppression system need to be professionally inspected?
Kitchen hood fire suppression systems are required to be serviced and/or inspected twice a year.

What does the inspection consist of?
A state licensed and certified FSS technician will do the following:


  • Review of all appliances, duct and plenum to insure they are properly covered with correct type and positioning of nozzles.
  • Ensure pressure gauge on cylinder is in proper range and cylinder is in good condition.
  • Perform system test without discharge to insure proper operation of the system components:
    • Manual pull station
    • Automatic gas valve
    • Electric shunt
    • Micro switch (controls make-up air, exhaust and fire alarm)

  • Clean nozzles to insure they are not plugged and verify protective caps are in place.
  • Verify proper placement and number of detection links.
  • Clean detection links (these are replaced annually).
  • Inspect piping that it is secure and free of damage.
  • Check for proper clearance between fryers and any cook tops or open flame.
  • Inspect cartridge weight of agent.
  • Verify dates on agent supply cylinder, wet chemical cylinders are required to be replaced or tested hydrostatically every 12 years.
  • Before leaving site, FSS technician will confirm the system is operational and current inspection tags are in place.
  • A copy of your inspection report will be provided to you at the time of each service.
