4. INSTALLATION
Refer to appropriate NFPA Installation Standards.
5. OPERATION
During fire conditions, when the temperature around the sprinkler approaches its operating temperature, the cover plate detaches.
Continued heating of the exposed sprinkler causes the fusible element to disengage, releasing the sealing assembly. Water flowing
through the sprinkler orifice strikes the flow shaper, 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
The Viking Model VK680 Sprinkler 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.
