Most of the Fires I have seen were motion detectors activated It was always a smoky type fire.
example:
A trash can were an ashtray was dumped into ccan and one of the butts were still hot enough to start smoldering.
A fire in a dumpster where smoke entered into a industrial type building and
set off motion.
the principal behind motions the manufactuers tell us is they see changes in heat a motion sees an intruder as heat and movement thru rays of the detector and 2 sets detector off.
At least thats how I understand it.Im sure the above refrenced report will shed much more light on the subject
