Hello,
What is the meaning of the maximum surveillance area of a smoke detector (A max) as it is defined in CEA 4040?
In Table 2 there are 2 possible values of Amax, but in Figure 7, there are many more.
Is there a difference between the definitions of Amax in Table 2 and Figure 7?
If i take for example a room of 25sqm and 3m height, flat ceiling, from Table 2 i find Amax=80sqm.
I cannot lookup this value in Figure 7…
The CEA 4040 document can be found here (in English).
Thank you
