Sidewall Sprinkler
A Sidewall Sprinkler is installed at the pipeline’s terminus to spray water to put out or suppress the fire. With only a partial deflector, a sidewall sprinkler is mounted on the wall beside or beneath a beam so that the water flowing out of the orifice shoots horizontally. Small rooms, hallways, and other areas where sprinkler pipes run up walls but not in the ceiling are protected by sidewall sprinklers.

Small rooms, hallways, and other areas where sprinkler pipes run up walls but not in the ceiling are protected by sidewall sprinklers.
For regular installation, sidewall sprinklers are intended for usage in low-risk situations. The plan offers a crescent-shaped water discharge pattern for placement right below a smooth ceiling, down a wall, or along the side of a beam.
Standard response (5 mm glass bulb) and rapid response (3 mm glass bulb) are the two temperature response types. It is the perfect option for standard coverage applications because of its rapid response type glass bulb and specific deflector, which combine speed of operation and area of coverage.
The sprinkler has high corrosion resistance thanks to the chrome plating in the majority of hostile conditions.
Feature
- Designed for use in light and ordinary hazard commercial occupancy
- Laser etched lot number on frame
- Solder link type
