The use of gaseous fire extinguishing systems to provide protection for computer and plant rooms is essential given the consequences of fire damage and downtime for such critical equipment. For a fire suppression system to work, the protected room must have sufficient integrity to retain an extinguishing concentration for a specified period after discharge. The British and International Standard BS:IS014520 requires that an enclosure integrity test be carried out at annual intervals. Testing is carried out using a door mounted fan to measure leakage flow and on completion a formal report is issued detailing results and any recommendations.

British Standard Design requirements...
- Install AFD to voids greater than 800mm
- Treat downward projections exceeding 10% of the void depth as wall
BS5839-Part 1:2013 states:
22.2d) If the system Category is such that automatic fire detection should be provided in any area that contains a horizontal void of 800 mm or more in height, automatic fire detection should also be provided in the void.
22.3j) Ceiling obstructions, such as structural beams, deeper than 10% of the overall ceiling height should be treated as walls [see Figure 10a)]. NOTE 10 Within horizontal voids, beams or obstructions that are deeper than 10% of the overall depth of the void regardless of whether the void is above the ceiling or below the floor, ought to be treated as walls that subdivide the void.
