Big "donkey's buttl" Fan, 10 feet wide

That appears to be mostly about how the fan effects a fire as well as the effect on a sprinkler system. What about any effects on fire detection? That is what my comment was about in my last post.

Detection probably still works with increased air movement but may be delayed because heat and smoke will not concentrate as much as with still air, which means more burning time before an alarm occurs.

I don't know what really happens but this seems logical it could be a potential problem.

It's easy to miss, but they indicate a 2-3 minute delay in activation, which other wise runs around 60 seconds for the test fire.
