Tyco WMA-1 Aluminum Finish Water Motor Gong for Fire Sprinkler Systems
The Tyco WMA-1 Water Motor Alarm in aluminum finish is a mechanical fire alarm designed to provide a loud and reliable signal when a fire sprinkler system activates. Instead of requiring electricity, this water motor gong uses flowing water from the sprinkler system to power a striker that hits the gong repeatedly, producing a sharp ringing tone that can be heard clearly during an emergency. With its aluminum finish, the gong maintains a professional appearance while offering the durability required for long-term fire protection.
Durable Aluminum Alloy Construction
This model features an aluminum alloy gong paired with a cast iron housing, galvanized steel nipples, and cast iron fittings. The natural aluminum finish makes it a strong, corrosion-resistant option that performs reliably in both interior and exterior fire protection applications. With a gong diameter of 8.5 inches, the Tyco WMA-1 delivers a penetrating alarm tone while maintaining a lighter overall weight of just 9.8 pounds for easier installation.
Designed for Versatility
The Tyco WMA-1 aluminum finish water motor alarm operates at pressures up to 300 PSI, making it suitable for a wide range of fire sprinkler system designs. It includes a 3/4 inch NPT water inlet and a 1 inch drain outlet for proper water flow and discharge. The alarm can be installed on walls up to 18 inches thick, giving contractors and facility managers flexibility for different building conditions without requiring additional modifications.
Code-Compliant with Third-Party Approvals
This water motor gong is UL Listed and FM Approved, meeting the rigorous requirements for safety and performance in NFPA 13 fire sprinkler systems. The Tyco WMA-1 aluminum finish version provides an audible alarm for systems with more than 20 sprinklers, ensuring compliance with code requirements and enhancing building safety without relying on electrical connections.
When Water Motor Gongs Are Required
Water motor gongs, also known as water motor alarms, are typically required by NFPA 13 and local fire codes for fire sprinkler systems exceeding 20 sprinklers. These alarms are often installed on exterior walls where they provide an audible warning to occupants and passersby while also helping firefighters locate fire department connections. The aluminum finish version offers the same performance as the red-painted model but with a natural metallic look that can suit architectural preferences or specific installation environments.
