2.
Generators are preferably mounted on the wall or at the ceiling, with the discharge opening pointing
downwards at an angle from the ceiling or wall respectively (cf. ‘discharge direction’ below). The higher
and or bigger the enclosed space, the more vertically downwards the generator should be directed. If a
space is protected by one generator only, it might be best to mount the generator pointing downwards in
the centre of the ceiling.
3.
The units need to be evenly distributed in the area.
One larger generator could be more cost effective than two smaller, the use of two generators could be
more effective than using four, but there are no absolutes. The deciding factor on the number of generators
in the design should be based on whether the chosen number could fill the area with aerosol rapidly and
evenly. After all, every nook and cranny need to be filled with sufficient aerosol. When in doubt, do not
hesitate to contact the AF-X Systems experts.

Determination of the correct discharge direction
There are always several solutions. The challenge is to come up with the optimal mix of choices in type, position
and discharge direction and length that makes maximum use of AF-X Fireblocker’s qualities and is in accordance
with the Statement of Requirements as well as the local rules and regulations.

Preferably, generators are mounted to the wall just under the ceiling with the discharge opening directed
downwards.
If a free downward outflow is not possible, the generators can be mounted on the ceiling, also with the
discharge opening directed downwards.
5.
Generators need to be positioned in such a way that all discharged aerosol is dispersed unhampered and
in full in the area to be protected. This also implies that the generators always need to be projected
towards unobstructed space, away from windows, doors, grates, vents, lids, valves, man-holes, transom
windows or other openings. This includes openings that are usually closed or pushed closed with door-
closers or automatically by the FECP before extinguishing starts.
