Room integrity testing – Blower door test

Room integrity testing and maintenance of the extinguishant concentration

Gielle does not only design, supply and install some of the most technically advanced fire suppression systems available, we also test and maintain equipment to check if your system is capable of responding to a fire emergency.

Your gas suppression system will only work effectively if the room containing your IT or electronic equipment has only limited leakage. If the room leaks, the fire suppression agent will escape before the fire is effectively controlled.

Room integrity testing (door fan test) is a procedure of analysis and verification of the sealing characteristics of a room, mandatory according to current regulations. It analyzes the behavior of the room during a pressure variation between inside and outside, which occurs during the discharge of gas, to verify if there is an air flow through the defects of the walls of the room that can make the gas discharge inefficient

With any gas fire suppression system – such as Inergen, 3M™ Novec™ 1230 or FM200 – the room must be sufficiently air tight to hold these gases at the designed concentration while they suppress the fire. Building joints and cable penetrations move over time introducing leak points that may not be noticed during normal building inspections.

Building maintenance activities may also inadvertently create places where gases can leak. That is why World Standard AS1851-2005 “Maintenance of fire protection systems and equipment” requires an Enclosure Integrity Test each year.

Vigilant facility managers take their duty of care seriously and checks that all parts of the fire detection and suppression system are ready to respond to protect critical assets. Our Room Integrity Testing calculates the leaktightness of a room. It predicts how long the extinguishing agent will remain at the correct concentration to effectively suppress the fire. Testing is quick and unintrusive. Room Integrity Testing can be organised at a time that will not disrupt your normal operations. It is an essential, yet simple, component of your fire protection regime.

Gielle Door Fan Test – easy, quick and reliable testing of room tightness

Quick and reliable extinguishing can be accomplished by building up and maintaining the required extinguishing concentration for a certain time. The room to be protected, therefore, needs to be sufficiently airtight. The Gielle Door Fan Test offers a simple, cost-effective, and environmentally friendly method for measuring room tightness and can also be used to directly locate leaks.
