Response to different fire scenarios 

The following tables show test results of detection distances and times for different fire scenarios. Each table 
lists results for a different sensitivity setting. For liquid fires the size of fire refers to the size of the pan, filled 
with the fuel. For gas fires the length of the plume is listed.
