Fire Suppression System Service Tips

Fire Suppression System Service Tips

Why do I need my fire suppression system serviced anyway?

The primary function of fire suppression equipment is to do just what its name implies.  When conditions arise, and fires flare up, the system is designed to automatically or manually suppress the fire until the professionals arrive in the big red truck.  However, we hope that never happens, and all the expenses of fire suppression and protection equipment are spent to never have needed them.

Keys to Keeping Fire Suppression Systems Working

To keep the system in good working order, like anything else, it requires regular maintenance.  Here are a few components of a system that need regular maintenance and why:

  1. Nozzles – They are the point where the fire suppressing agent inside the system tanks is distributed onto the fire.  Spray patterns, flowrates, positioning are all critical components.  Regular maintenance ensures that nozzles are open, clear and aimed at the proper location.  These nozzles above fryers or char-broilers often get filled with grease.
  2. Fusible Links – These are the key to the system automatically detecting a fire on or over the kitchen appliances.  They are made from a metal alloy that melts at specific temperatures, which discharges the system.  They have an undetermined shelf life, but only a 6-month service life.  Due to the constant heating and cooling cycles they undergo in restaurants every day, fatigue and other stresses warrant regular replacement.  In fact, Fire Code and Manufacturer Recommendations REQUIRE fusible link replacement 6 months after installing them.
  3. Micro-Switches – They control electrical shut down of appliances, and ensure proper operation of the fans.  In a fire, we want the exhaust fan running to pull smoke and heat out of the building.  But we want the return fresh air to stop, so it doesn’t feed the fire.  The actual switches will last for years, but often times when remodeling or other electrical work in the building is performed, this important sequencing of fans is interrupted.  Regular maintenance ensures the switches work properly.
  4. Miscellanous components – there are other components such as cartridges, gas valves, and remote pulls that must also be checked or replaced periodically to make sure the system will work normally.

State of Florida’s Fire Suppression System Maintenance Requirements

Finally, semi-annual fire suppression system maintenance is required by your insurance provider and by Florida law.  Failure to properly maintain fire suppression systems per manufacturer’s recommendations may jeopardize insurance policy coverage and/or policy continuation.  Your local Fire Marshall (Authority Having Jurisdiction) can even force your business closure until proper maintenance has been performed and verified.
