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.
Sprinklers are attached to pipes installed in a building's walls (like plumbing) that keep water ready in case of fire. Sprinklers have a fusible link that melts from heat given off by a fire. This opens the sprinkler, and water flows out in a spray pattern, putting water directly on the flames. Only the sprinkler(s) closest to a fire will open.
