An upright sprinkler comes with a water deflector at the top so that water coming out of the orifice shoots upward and then spreads in a circular pattern. Upright sprinklers, used mostly in warehouses or large structural buildings, do not hide behind the ceiling.

The pendent sprinklers produce a hemispherical water distribution pattern below the deflector. During a fire the thermal-sensitive liquid in the glass bulb expands, causing the bulb to shatter, releasing the button and spring seal assembly.

The head of sidewall sprinklers provide one side (parabolic) water distribution outward from a wall. The sprinklers are available in various temperature ratings and finishes to meet several design requirements.

Concealed pendent sprinklers have a low profile and aesthetically pleasing design. All that is seen at the ceiling is a 3-5/16″ diameter ceiling plate, colour finished to match the specifier’s exact requirements.
