Tutorial 7 - Inverse Square Law and FOV Multipliers

 

 

The Field-Of-View (FOV) Multiplier is a value which extends or degrades the maximum range for flame detectors in the project. A value of 1 indicates no change to the maximum range. This property is useful in conjunction with the inverse square law to perform analyses for varying fire sizes.

 

The FOV Multiplier is a property of risk grades in Detect3D which can be made Visible to appear in the 3D window or can be assigned to zones or sub-zones in the project. This is the same for gas cloud sizes as discussed in Tutorial 6.

 

Learning objects for this tutorial include how to:

• Use Detect3D's inverse square law tool

• Edit the FOV Multiplier value for existing risk grades

• Change the Visible risk grade

• Review coverage of a zone with a risk grade containing a FOV multiplier value
