A pendant sprinkler head is a type of fire sprinkler commonly used in architectural design for fire protection systems. It is installed on the ceiling with its head facing downward, allowing water to be discharged in a circular pattern below.
This design is particularly effective for covering large areas and ensuring even water distribution. Pendant sprinklers are often chosen for spaces with finished ceilings, such as offices, hotels, and residential buildings, where they blend seamlessly with the ceiling surface.
Additionally, they come in various styles and finishes to complement interior aesthetics while prioritizing safety and compliance with fire codes.

A pendant sprinkler head detail drawing in construction typically shows the installation and components of the sprinkler system, focusing on how the pendant sprinkler integrates with the ceiling, piping, and structural elements.
Key elements in the drawing include:
- Sprinkler Head: The pendant head itself, positioned below the ceiling, with its deflector plate designed to distribute water evenly.
- Escutcheon Plate (if used): A decorative and functional cover that conceals the gap between the sprinkler head and the ceiling.
- Branch Pipe: The horizontal pipe that supplies water to the sprinkler head, connecting it to the main water line.
- Drop or Arm-over Pipe: A vertical pipe section that connects the branch pipe to the sprinkler head, ensuring proper positioning below the ceiling.
- Ceiling Structure: Indication of the ceiling material and thickness, whether it’s drywall, concrete, or a suspended ceiling system.
- Clearance Requirements: Dimensions showing the required clearance around the sprinkler head, ensuring unobstructed water spray in case of activation.
- Hanger Support: Details of pipe hangers or supports that secure the pipes to the building structure.
- Notes and Annotations: Any installation guidelines, fire code references, or special conditions required by the design.
