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.
A sprinkler system will control a fire with a fraction of the water used by fire department hoses. On average, the fire department will use eight times the amount of water compared to a sprinkler for the same fire. In the largest study in the US (The Scottsdale Report) 92% of fires were controlled with two or less sprinklers.
