The Viking Water Motor Alarm Package F-2 is a mechanical fire protection notification device engineered to provide immediate, audible alerts during water flow events in commercial and industrial fire sprinkler assemblies. Operating entirely without electrical power or backup batteries, this mechanical gong automatically sounds a persistent alarm when a sprinkler activates, ensuring continuous life safety notification and emergency response even during total electrical grid failures.
This assembly satisfies critical design, installation, and periodic testing mandates governed by NFPA 13 for the installation of sprinkler systems and NFPA 25 for the inspection, testing, and maintenance of water-based fire protection systems. The inclusion of a 3/4" NPT strainer protects internal components from line sediment and debris, supporting long-term operational integrity and compliance with rigorous industry safety codes.
