SPRINKLER OPERATION
The operating mechanism is a frangible glass bulb which contains
a heat responsive liquid. During a re, the ambient temperature
rises causing the liquid in the bulb to expand.
When the ambient temperature reaches the rated temperature
of the sprinkler, the bulb shatters. As a result, the waterway is
cleared of all sealing parts and water is discharged towards the
de ector. The de ector is designed to distribute the water in a
pattern that is most effective in controlling the re.
