Sprinklers are among the most effective fire protection systems available, ready to snuff out developing flames at a moment’s notice. While most sprinkler heads are similar in appearance, there are several varieties suited to different needs and preferences. Take a look at this guide on the different systems when you're ready to install fire protection in your building.

A Guide to Sprinkler Head Types

1. Upright

Upright sprinklers point straight up from the pipes supplying them, spraying water onto the underside of a convex disc that disperses it in a dome-like pattern. They’re best suited for difficult-to-access areas or areas containing obstructions that might interfere with the effectiveness of sidewall or pendent fire sprinklers. Uprights are often preferred in cold or ice-prone areas, since the heads won’t collect dust or ice that could prevent them from functioning.

2. Sidewall

These sprinklers are mounted perpendicularly to walls, typically in areas where overhead pipes are not available or where aesthetic concerns prevent the use of other types. They’re equipped with semi-circular deflector discs, which produce a crescent-shaped pattern. Sidewall sprinklers are usually seen in hallways, closets, utility rooms, and other restricted areas or spaces where water pipes run through walls. They’re typically found in hotels, restaurants, and other commercial buildings or buildings accessible to the public.

3. Pendent

The most common type of sprinkler, pendents hang exposed from overhead pipes and use convex discs to disperse pressurized water over large areas. These sprinklers typically provide the greatest amount of coverage among sprinklers and are popular for fire control measures in buildings at industrial sites and commercial locations.

4. Concealed Pendent

Operating on the same principle as normal pendent sprinklers, these are recessed into ceilings and covered with a detachable plate. At 20 degrees below the sprinkler system activation temperature, the plate will break away and expose the sprinkler heads so that water can be dispersed freely when temperatures become hot enough to activate them. The concealing plate makes these a popular choice for office spaces and public buildings where management wants to present a clean, professional appearance.
