Viking VK470 Residential Pendent Fire Sprinkler Torque-Assist

The Viking VK470 Residential Pendent Fire Sprinkler with Torque-Assist is a ceiling-mounted fire suppression component designed for wet pipe fire protection assemblies in one- and two-family dwellings. Installed pendent-style to hang below the ceiling line, it discharges water in a wide, round spray pattern to cover the floor area below. The unit operates via a thermosensitive glass bulb that expands and shatters at a rated temperature, triggering rapid water discharge for early flame control.

This sprinkler is engineered to satisfy residential fire safety code requirements specified in NFPA 13D. Proper installation ensures compliance with local life safety codes, providing reliable activation and maximized protective coverage for residential building layouts.
