Viking VK545 Standard Response Recessed Dry Pendent Fire Sprinkler

The Viking VK545 Standard Response Recessed Dry Pendent Fire Sprinkler provides reliable fire suppression in cold and unheated environments where freezing temperatures threaten traditional wet pipe assemblies. Designed to install in dry, wet, pre-action, and deluge fire protection networks, this unit keeps water sequestered above the heated space boundary until thermal activation occurs, preventing pipe freeze-ups, bursting, and corrosion.

This sprinkler satisfies NFPA 13 installation requirements for commercial and industrial facilities such as cold storage rooms, warehouses, and parking garages. Its engineered dry pendent configuration and standard response mechanism deliver effective water distribution while satisfying strict life safety codes.
