Fire Suppression

If you manage a property or own a business, you probably have heard about the importance of fire protection systems, but do you know the difference between a sprinkler system and a suppression system? Do you know how fire suppression systems work or how to choose the right fire protection system for your establishment? It is imperative that you understand what fire suppression systems are and which work best in different scenarios. The wrong fire suppression system has the potential to cause more harm than an actual fire.

What is a Fire Suppression System?

A fire suppression system is used to stop fire from spreading within a building or extinguish it entirely. A suppression system uses a mix of dry chemicals and/or wet agents in order to quickly neutralise equipment fires before they escalate.

By installing a fire suppression system at your business premises, you can drastically reduce the risk of serious damage being caused by a fire. These fire protection systems can also provide peace of mind that your building is safe from fire, even when it is empty. This is because they function automatically.

A fire suppression system is an engineered group of units that are built to extinguish fires through the application of a substance. Most commonly, a fire suppression system has built-in components that detect fires at the beginning stages through heat, smoke, and other warning signals. These are attached to an alarm system that will alert you when the fire has been detected and initiate steps for action to further suppress the fire.

The majority of fire suppression systems will automatically release the application of an external substance to extinguish the fire after the detection and/or alert. However, some fire suppression systems have a manual application release.

The Benefits of an Automatic Fire Suppression System

  • Safe and easy to use: these systems are designed to activate automatically, so they don’t require a person to initiate an activation.
  • Early detection: compared to fire detection systems of the past, these modern fire suppression devices offer immediate response to fire and smoke.
  • Eliminate fuel sources: removing the electrical or fuel source contained within equipment will ensure the fire isn’t continuing to be fed. Fire suppression systems eliminate the fuel source quickly, limiting any damage.
  • Suitable for most locations: fire suppression systems can be installed in almost any area and are most suited to environments such as data centres, archive rooms and server stores.
  • Tested and compliant: fire suppression systems are tested in laboratory settings to ensure they work efficiently to extinguish a fire. All of our systems are also designed to be compliant with industry regulations.

Types of Fire Suppression Systems

Sprinkler systems. Water mist systems. Foam systems. Gaseous suppression systems. Hydrant and hose reel

  • Fire Sprinkler Systems
    Fire sprinkler systems are intended to actively provide a means to suppress or extinguish fire in an emergency situation. The four main types of sprinkler systems are:- wet system, dry system, pre-action system and deluge system.
  • Gas Suppression Systems
    Gas suppression systems are commonly employed in areas that are highly volatile, critical or contain sensitive equipment where non-fire damage from water is as detrimental to the equipment or materials as fire.
  • Hydrants & Hose Reels
    Fire hydrant and hose reel systems are an installation of pipes, water tanks, pumps, hydrant outlets and/or hose reels in a building to provide a ready means by which a flow of water can be delivered in any part of the building for the purpose of fire fighting.

Clean Agent fire suppression systems

Clean Agent fire suppression systems use environmentally friendly chemical reagents to extinguish fires in sensitive spaces like data centers. The clean-up is minimal, water-free, and safe for the environment.


Clean agents are colorless, odorless, electrically non-conductive, leave no residue, and are safe for humans. Clean agents interrupt the chemical chain of fire, accelerating suppression and absorbing heat, without damaging sensitive equipment or electronics. Protect high-value assets like data centers or priceless artifacts in a museum with waterless, environmentally friendly clean agents. Keystone proudly designs and installs clean agent fire suppression systems from the industry’s leading fire suppression manufacturer, Kidde Fire Systems.


Wet chemical agents overcome flames quickly and clean up easily. A wet chemical fire suppression system reduces downtime better than a dry chemical system. Today’s high temperature cooking appliances present unique fire protection challenges for your employees, your customers, and your business. Thus, a restaurant fire suppression system is crucial to ensure that your business operates safely and effectively. Restaurant fire suppression systems are specifically designed to handle the suppression needs of kitchens to quickly extinguish fires and clean up easily, reducing downtime.


Dry chemical suppression systems are a great choice for areas where sprinklers and water are not preferred. They are specifically designed to meet the unique demands of rigorous industrial hazards typically found in manufacturing environments. While dry chemical systems have one of the least desirable cleanup profiles, they are one of the least expensive fire suppression systems to install and maintain. IND systems, as they are known, offer the choice of two dry chemical agents, ABC Powder and BC Powder. ABC Powder (monoammonium phosphate) is a multipurpose agent and can be used for Class A hazards like wood, paper, and other ordinary combustibles. BC Powder (sodium bicarbonate) is most effective on Class B flammable liquid fires and Class C electrical fires.

Gas Fire Suppression – FM200 and Novec 1230

A gaseous fire suppression system extinguishes a fire through releasing an agent. This agent works by either reducing the oxygen levels in the area, reducing the chemical reaction within the atmosphere or cooling the fire enough so it dissipates.

We design, install and maintain two main types of gaseous fire suppression systems; Novec 1230 systems and FM200 systems. Both of these systems are synthetic gas suppression systems, and are designed to work quickly and efficiently, and require minimal clean up afterwards

Novec 1230 suppression systems are environmentally friendly and both the Noves 1230 and FM200 are safe to use in areas where personnel are present.

VESDA Detection

VESDA (very early smoke detecting apparatus) is the world’s leading air aspirating smoke detection equipment. Combined with a FM200 or Novec 1230 fire suppression system, VESDA smoke detection provides a highly reliable fire safety system for your business.

Room Integrity Testing

However, before any fire suppression system can be designed and installed, the area to be protected must be subjected to a room integrity test. A room integrity test ensures that the fire suppression system will work properly and extinguish a fire by checking enough gas is contained within the designated space for a set period of time.

Electrical fire suppression

Special suppression systems can be installed to extinguish fires in areas at risk of electrical fires. An electrical fire suppression system is the ideal solution if you’re looking to protect an enclosed room, which contains a lot of electrical equipment. For example, you may elect to use this fire protection system to protect a server room or telecoms enclosure.
