Viking VK544 Standard Response Dry Pendent Fire Sprinkler

The Viking VK544 Standard Response Dry Pendent Fire Sprinkler provides dependable fire suppression in unheated or cold spaces prone to freezing temperatures, such as parking garages, cold storage areas, and attics. Installed directly into dry pipe or preaction fire suppression systems, the dry pendent design keeps water out of the nipple and barrel until the thermal element activates, effectively eliminating freeze damage risks and ensuring continuous system readiness.

Engineered for strict industry compliance, this sprinkler meets rigorous life safety regulations under NFPA standards and holds UL Listing and FM Approved certifications. It satisfies mandatory commercial and industrial code requirements for fire protection in environments where standard wet pipe systems are unsuitable.
