Room Integrity Fan Testing
The largest failure of gaseous fire suppression systems is as a result of loss of extinguishant through openings in the protected room.
Gaseous fire suppression systems rely on their ability to correctly extinguish a fire in a room or enclosure by achieving a minimum concentration and retaining this concentration for a specified soak period.
Many fire suppression systems fail because they either don’t achieve the correct minimum concentration or more likely, because they lose the correct concentration before the expiry of the specified soak period thus allowing the fire to rekindle.
Rather than perform an actual discharge test of the fire suppression gas which can prove to be quite costly and difficult to arrange, it is possible to perform a Room Integrity Fan Test. This is an approved alternative to performing an actual discharge test in commissioning of a fire extinguishing system.
