Vanguard designed Clean Agent systems are painstakingly engineered and designed to perform reliably.  However, to ensure the effetiveness of the system, the space must be tested for its capacity to hold the clean agent.  This is "Room Integrity" testing and a service provided by Vanguard for any Clean Agent system.

The test equipment comprises of variable speed fans, expandable door panels, pressure gauges and a dedicated portable computer. The door fan unit is fitted into a doorway of the protected area by means of the expandable door panels designed to fit most door frame sizes, and measures the size of holes in the room and the pressures that may exit across them.

The computer then converts the test readings into an Equivalent Leakage Area, or the total area of all the cracks, gaps and holes in the test area. The data generated is then processed using specifically designed computer software, in compliance with the National Fire Protection Association (NFPA) which predicts the period of time that the concentration will be held in the test area at any given height. This retention time can be further calculated for different heights.

"Room Integrity" tests should be carried out at the design stage of a Clean Agent systems and annually thereafter--and even more frequently if the space may have changed due to renovations, or layout changes.

This testing determines the exact design of the clean agetn system, and may also indicate a need for other work needing to take place in order to seal gaps within the space to be protected.
