Fig. 4.18: Pipe system in front of the air inlet of a climatic cabinet with circulating air
High aspiration potential
If the climatic cabinets have a high aspiration potential the flow speed
near the air inlets or air outlets is very high. Therefore, a high pressure is
produced which affects the response behaviour during the smoke detec-
tion. In such cases the
pipe system is to be removed from the pres-
sure area
or is installed in a distance at which the air speed is
≤
2 m/s
(refer to Fig. 4.18). If this is not possible for constructional reasons an air
return is to be installed.
The pipe system in the floor void is also to be installed outside of the
pressure area. The distance to the air outlet can be up to 1 m.
