An Upright Fire Sprinkler is a type of sprinkler head used in fire protection systems, designed to provide effective fire suppression in various environments. It is mounted above the ceiling, with the sprinkler head facing upward. When activated by heat, the sprinkler discharges water in a downward spray pattern to cover the area below.

This design is typically used in spaces with high ceilings or areas where overhead obstructions may interfere with other types of sprinkler heads. The water spray is dispersed in a circular pattern, ensuring wide coverage of the affected area. Upright sprinklers are commonly found in warehouses, industrial buildings, and large commercial spaces.

The heat-sensitive element in the sprinkler head, often a glass bulb or fusible link, breaks when exposed to temperatures around 155°F (68°C), triggering the water flow. Upright fire sprinklers are ideal for environments where efficient, widespread water distribution is crucial for early fire suppression.
