Description

UL listed concealed sprinkler act in the same manner as regular fire suppression systems with the fire detection and extinguishing function, but these are designed to be hidden from plain sight. They are designed for spaces that do not want to interfere with clearance levels or aesthetic appeal.

Normally type used: 68 Degree with Standard response.

This sprinkler is UL Listed.

Operation of sprinkler spray nozzle
In case of fire, the thermosensitive liquid in the glass bulb will quickly expand, which will result in the blasting of glass bulb and discharging the seal assemblies, such as stopper and springs. The water flowing through sprinkler orifice will lash against the sprinkle-nozzle deflector, which will then form uniform sprinkling water flow to control or extinguish the fire.
