4. INSTALLATION
Refer to appropriate NFPA, FM Global, and/or any other applicable installation standards.
5. OPERATION
During fire conditions, when the temperature around the sprinkler reaches its operating temperature, the heat-sensitive liquid in the
glass bulb expands, causing the bulb to shatter, releasing the pip cap assembly. Water flowing through the sprinkler orifice strikes
the sprinkler deflector, forming a uniform spray pattern to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
7. AVAILABILITY
Viking Sprinkler Model VK377 is available through a network of domestic and international distributors. See The Viking Corporation
web site for the closest distributor or contact The Viking Corporation.
8. GUARANTEE
