In what systems or equipment is the Alarm Check Valve typically used?
The Alarm Check Valve (ACV) is typically used in wet pipe fire sprinkler systems, which are the most common type of fire protection system in buildings. These systems are filled with water under pressure, ready to discharge immediately when a sprinkler head is activated by heat from a fire. The ACV is installed in the main water supply line of the system and serves two key purposes: it ensures water flows in one direction to prevent backflow, and it activates an alarm when water begins to flow, signaling a fire event.
Additionally, ACVs are often integrated with fire alarm systems and water flow indicators to provide early detection and notification of fire incidents. They are commonly found in commercial, industrial, and residential buildings, such as offices, warehouses, schools, and hospitals, where reliable fire protection is essential. The ACV is a critical component for maintaining system integrity and ensuring rapid response during emergencies.
