5. OPERATION
During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the glass to shatter, releasing the pip cap and
sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern
to extinguish or control the fire.

Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
