UL 300 Standard

Underwriters Laboratories (UL) introduced the UL 300 Standard in 1994, updating the testing procedures and requirements for kitchen fire suppression systems. 

With dramatic shifts in cooking methods and appliance quality, new standards were required to effectively extinguish fires. Make sure your fire suppression system meets these standards.

The Most Popular Restaurant Fire Suppression Systems

If you’re looking for reliable fire suppression systems for restaurants, here are some of the top choices on the market today:

ANSUL R-102 Restaurant Fire Suppression System

The R-102 system uses a low-pH liquid agent that not only extinguishes flames and cools heated surfaces but also reacts with grease to create a foam barrier that prevents grease fires from reigniting after their initial suppression.

This system is extremely appliance-friendly, and it can be adapted to a wide range of settings.

ANSUL PIRANHA Dual Agent Fire Suppression System

This advanced fire suppression system combines a liquid chemical fire suppressing agent with the superior cooling power of water. 

The liquid chemicals are deployed first, helping to quickly tamp down any flames and create a vapor barrier to prevent reignition. 

The second step is a water spray, helping to rapidly cool all cooking surfaces and flammable materials and preventing flares from erupting again.

The PIRANHA Dual Agent system provides twice as much coverage as other systems, and the combination of suppression methods can cool down cooking oils up to 15 times faster. This also allows you to reduce the need for chemical suppression agents by up to 60%.


The KITCHEN KNIGHT II system uses a potassium carbonate solution to quickly knock down fires and prevent flares after flames are extinguished. This system is easy to install, thanks to its cylinder control head and unbalanced piping network. 

The KITCHEN KNIGHT II can also be triggered automatically and manually, adding an additional layer of safety if staff feels the need to trigger the system before the sensors detect a fire.

ANSUL Restaurant Electric Detection (RED)

Adding electric detection to your fire suppression system helps you to monitor your kitchen 24/7, even if you’re maintaining a facility with several remote kitchens, like stadiums or other large structures.

ANSUL’s RED technology integrates seamlessly with both the R-102 and PIRANHA systems, so you can rest assured that your fire suppression systems are ready to go at all times. You’ll also know the moment one of your suppression systems is deployed.
