A Gaseous fire suppression system is often used in Data and electrical switch rooms it is highly effective at protecting your premises from the disruptive forces of fire. The system works by releasing a gas agent into the protected area which reacts with the fire or reduces the oxygen level which then suppresses or extinguishes the fire.

The gas needs to be retained in the protected area for a period in order to extinguish the fire (usually around 10 minutes) and it is therefore important that the room is adequately sealed.

The system is interconnected to a fire detection and alarm system which it is often designed in a two stage format if one detector is activated a sounder will be triggered if two detectors then following a countdown timer activate the suppression system will be triggered. This design keeps any possible false alarm to a minimum.

A manual call point can be used to trigger the gas manually if required.

Benefits of a gaseous fire suppression system include

  • No residue after activation so no cleaning up required
  • Environmentally safe 
  • Quick deployment, clean agents can put out the fire within 10 seconds 
  • Ideal for Data Centres, server rooms and cabinets, switch rooms 

Room Integrity Testing

Testing of the room's integrity for leaks must be carried out at least once a year in accordance with ISO 15004 and BAFE-SP203-3 and more often if the room has been subject to any alteration work. For example, a hole drilled through the wall to accommodate electrical cabling or pipework which hasn't been sealed adequately, or a new door fitted may cause the test (and ultimately the fire suppression system) to fail.

The test involves using specialised equipment. The room is sealed off at the entrance door and a fan unit attached to pressurise the room. Measurements of the leakage are then taken and depending on the results of the predicted retention time the test will pass or fail.
