calculate a distance between radiant -sensing fire detector and the fire release

[zarroukbouhlel]

thanks for your explanation , my problem is near from the solution , it remain how can i determinate the fire release HRR , i don't know i use the max of HRR from the rate heat release curve or what ? , also i searched in some flame detectors datasheet but i dont found the test fire relitives values provided by the testing agency .
thanks in advance

Pickup a copy of the SFPE Handbook as it has all of the formulas. Then do a "Google" search for the term "Heat Release Rate Formula" and you come across a number of references, including the below PDF's:
