4. INSTALLATION
Refer to appropriate NFPA or EN 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 over a specific area of coverage determined
by the water supply pressure at the sprinkler to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
