Upright fire sprinklers stand upright...imagine that! An upright sprinkler sprays water upwards and the deflector deflects the water back down. Upright fire sprinklers are suited for areas that are difficult to access, like around beams, ducts, and other ceiling obstructions, or in ceilings without a finish (eg., no drop ceiling or drywall). These sprinklers are commonly found in buildings with exposed ceilings, like many chic restaurants or mechanical rooms. It may be useful to think of an upright fire sprinkler like an upside down pendent fire sprinkler, only with a concave deflector.

Take a peek at the two upright fire sprinklers below. The left is the TY313, which is quick response and the right is the TY315, which is standard response, both of which are shown in brass. Just like the pendent fire sprinklers, you can see the size difference in the bulbs, which, as you should know by now, correlates to the response type. If you look at the deflector, it's curved so that the water will deflect downward. Don't they look like upside down pendent sprinklers?

Just like pendent fire sprinklers, upright fire sprinklers are available in the temperature range of 135 to 360 degrees Fahrenheit. While they are available in chrome and white, the most common finish for an upright fire sprinkler is simply brass.
