A Fire Suppression system suppresses a fire through releasing an agent to either reduce the oxygen, reduce the chemical reaction within the atmosphere or cool the fire.

Once a fire has been detected, by either the manual or automatic detection, a notification is sent to the panel which in turn releases the agent.

Fire sprinkler and fire suppression systems share a common purpose. Parts of their systems may look similar, but fire sprinkler and suppression systems are very different in the way they extinguish or control fires and their applications. There are even several types of fire sprinkler and suppression systems.

The main differences between a fire sprinkler and fire suppression systems are how they extinguish fires and when each system would be ideal to use. Fire sprinklers use water to extinguish and control fires, while fire suppression systems can use a number of different agents. It is important to determine if water from fire sprinklers will cause additional damage to the property before deciding on using a sprinkler or suppression system.

We know from experience that choosing the correct fire suppression system for your organisation can be a bit of a minefield, from knowing why you need one, to which type of system is required and choosing a reliable and trustworthy company to fit it.

Types of Fire Suppression System

1. Gas System – FM200/Novac 1230/Inergent/Co2 Flooding.

Gas systems are stored as a liquid, with nitrogen used to pressurise it. gas fire suppression, when released the FM200/Novac 1230/Inergent/Co2 chemical agent, has a chemical reaction with the fire and extinguishes it. This type of system is best suited to data rooms, switch rooms or communication rooms

2. Water mist System

Water mist systems are commonly replacing sprinklers in big data rooms, other large areas and local applications. These systems can be used for flammable liquids and electrical rooms, the mist evaporates and causes a starving of oxygen effect rather than cooling.

3. Foam Deluge System

Foam deluge systems are mainly suitable for large applications where you cannot use water or gas. These tend to be external such as transformers, oil tanks and oil storage silos. A simple sprinkler type application disperses a foam concentrate mixed with the water to provide the typical expanding agent (the same as with extinguishers).

4. Pneumatic Heat Detection Tube

pneumatic heat detection tube very simple, cost-effective and easy to install solution, this is entry-level equipment for fire suppression. Basically an extinguisher with a valve and a length of heat detection tube which acts as the detection and propellant feed for the agent to be used. When a flame or temperature reaches a certain level around the pipe it blows a hole in the pipe (a very small pressurised hole) which then propels the agent directly onto the risk. Ideal for vehicles, small machinery, electrical switch cabinets, fume cupboards and areas with no room integrity.
