Fire sprinkler is a key component part of automatic fire extinguishing system, it aims to detect fire and control or extinguish the fire through sprinkler.

Pendent Sprinkler is a small, thermo sensitive, glass-bulb spray sprinkler available in several different finishes and temperature ratings to meet design requirements. During fire, the heat-sensitive liquid in the glass bulb expands, causing the glass bulb to shatter. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern in order to control or extinguish fire.
