Operation:
Upon fire initiation within a protected hazard, the temperature inside the hazard rises fusing the solder
between the cover plate and its assembly. A spring on the Sprinkler Cover Plate Assembly ensures
the ejection of the cover plate from its assembly. The rising heat causes the liquid inside the Thermo-
Sensitive bulb to expand. The liquid expansion causes the glass bulb to break, releasing the bulb seat
assembly. The water discharges through the sprinkler orifice striking the deflector producing a uniform
distribution pattern within the hazard area.
