INSTALLATION <br /> Refer to appropriate NFPA Installation Standards. <br /> 5. OPERATION <br /> During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the glass to shatter, releasing the pip cap and <br /> sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern <br /> to extinguish or control the fire. <br /> 6. INSPECTIONS, TESTS AND MAINTENANCE <br /> Refer to NFPA 25 for Inspection, Testing and Maintenance requirements. <br /> 7. AVAILABILITY <br /> The Viking Microfasr Quick Response Upright Sprinkler VK350 is available through a network of domestic and international distributors. <br /> See The Viking Corporation web site for the closest distributor or contact The Viking Corporation. <br /> 8.
