Report Abuse. Sprinklers do not detect smoke. Some operate by a fuse that melts, from the heat of a fire, to release water, others operate by a sudden drop in water or air pressure in the pipe which is controlled by a alarm system, when activated.
Unfortunately, some causes of smelling cigarette smoke when nobody is smoking are very serious. âThese phantom smells can be caused by damage to the olfactory nerve by chemicals, or infection with a virus or bacteria, or trauma. A tumor of the brain or the olfactory nerve can also cause phantom smells.
