What is the maximum distance from wall to sprinkler head?
Again, normally, standard spray sprinklers can be placed up to 7. Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below. This is done to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.
What are the 4 types of sprinkler heads?
The four main types of fire sprinkler heads are Pendent, Upright, Sidewall, and Concealed. Each type is designed for a specific orientation and application, ensuring optimal water distribution to suppress a fire effectively. The most common sprinkler head uses a small glass bulb filled with a glycerin-based liquid. This bulb contains an air bubble to allow for normal thermal expansion. When exposed to fire-generated heat, the liquid expands until it shatters the bulb, releasing the plug and allowing water to flow.
