Fire Protection Alarm Check Valve

A Fire Protection Alarm Check Valve is a specialized device designed to ensure reliable water flow in fire sprinkler and standpipe systems while providing critical monitoring and alarm functions. It combines the features of a traditional check valve-which prevents backflow-with integrated alarm mechanisms to alert personnel of system activation or malfunctions.

The primary role of this valve is to maintain unidirectional water flow, ensuring that pressurized water from the fire pump or city supply moves only toward the sprinkler heads or hoses. This prevents contamination of the water supply and protects system components from damage caused by reverse pressure. Additionally, the built-in alarm system triggers audible and visual signals when water flows through the valve, indicating that the fire protection system has been activated.

Check Valve Body: Constructed from durable materials like bronze or stainless steel to withstand high pressure and corrosion.
Alarm Switch: A mechanical or electronic sensor that detects water movement and activates alarms.
Water Motor Gong (Optional): A traditional mechanical alarm that sounds when water flows, often used in outdoor or industrial settings.
Pressure Gauges: Monitor inlet and outlet pressure to ensure system integrity.
Drain and Test Connections: Allow for routine maintenance and verification of alarm functionality.
