Integrity Testing

Today, some of the largest and most successful companies trust Prana Fm to service and maintain their fire systems. Those same companies protect their most valuable assets by using Prana Fm to help them achieve that, our service team provides unmatched performance when it comes to Room Integrity Testing, Inspecting and Maintenance of fire systems.

Importance of Room Integrity Testing (Door Fan Test)

Room Integrity Testing is vital to ensure your protected area is properly sealed so your suppression agent won’t escape allowing the fire to possibly re-ignite. To ensure the effectiveness of your Clean Agent fire suppression system, the integrity of the room to hold the gas is a critical factor
Our service providers are trained on how to use Room Integrity Testing equipment. Our commitment to use state of the art testing equipment assures you will receive the most accurate information available. Integrity Testing performed by Prana FM gives you the peace of mind of knowing the fire suppression system will hold the concentration of agent as designed.

We have the solutions and the expertise to deliver on your requirements.

When should integrity tests be done?

An integrity test should be performed immediately after a system has been installed and routinely every year thereafter. Any alteration such as changing a door, putting a cable/s in or even replacing equipment can affect the rooms (enclosures) gas holding ability (Integrity), routine servicing of equipment will not reveal this, so an Integrity Test should be carried out after any alteration and the annual testing dates adjusted to follow annually thereafter.

The purpose of Integrity Test is to determine the time that an extinguishant /air mixture will remain active in an enclosure at the designated protected height (i.e. how long the extinguishing agent will remain in an ‘effective manner’ within an enclosure). This is achieved by equating it to measured leakage occurring from an enclosure; this leakage being that capable of permitting the extinguishing agent to escape from the confines of an area and allowing the concentration to diminish.
As part of the ISO 14520, NFPA and BFPSA Codes of Practice for Gaseous Fire Fighting Systems, integrity testing should be undertaken in a protected area, to determine whether leakage could impact upon the extinguishant performance. Ideally this is done at the onset (when it is first installed) and then regularly as part of the routine maintenance, once a year.

Leakage and smoke ingress are detrimental to an installation’s fire fighting capabilities, and can impact upon the ability to operate as intended, prevent fire or provide effective extinguishant.
