4 Planning
In this chapter you will learn how to arrange the flame detector for optimum room
monitoring and how you determine the mounting site and appropriate parameter
set.
Sequence
1. Establish flame detector arrangement [ 27]
2. Defining the place of mounting [ 31]
3. Mask deceptive phenomena [ 35]
4. Determine parameter set [ 36]
Information on the individual steps can be found in the specified chapters.
4.1 Establish flame detector arrangement
Select the flame detector quantity, arrangement and alignment such that the area
is equally monitored. The monitoring area of a flame detector is shaped like a
rotationally symmetrical taper with an opening angle of 90°.
Figure 7: Monitoring area of flame detector
In a typical application, the flame detector is fitted at an angle of 45° to the wall in
one of the ceiling corners.
Observe the following points during detector arrangement:
Line of sight to area which is to be monitored
Arrangement of several flame detectors
Deceptive phenomena
Information on these points can be found in the following chapters. You will find
several examples of application after this.
