The sprinkler is composed of sprinkler frame, sealant and glass
bulb. It is to be installed in the protective district via
ductwork, acting as a fire detector and auto sprayer. In case of
fire inside the protective district, the atmosphere temperature
rises up and the liquid inside the glass bulb expands after being
heated and explodes after reaching the operating temperature of the
glass ball. The sealant drops and the sprinkler sprays to the
protective district for fire extinguishments subject to the preset
shape of spraying.

During installation, should pay attention not to damage the bulb to avoid affect the thermal performance. In the
process of wrench and twist, do not use the spanner to wrench the supporting arm to deformation and affect the
sealing performance (note: the bulb temperature can be chosen according to the needs of users)
