Alarm Checks

Alarm check valves are fire protection system components used in wet pipe sprinkler systems to control water flow and activate alarm devices when water begins flowing due to sprinkler activation. These valves help ensure proper system operation by preventing backflow while allowing system pressure changes to trigger mechanical or hydraulic alarm signaling devices. Commonly used in commercial, industrial, institutional, and residential fire protection systems, alarm check valves are typically installed in system risers and are essential for code-compliant sprinkler system operation. Available in flanged and grooved configurations, alarm check valves are designed for reliable performance in UL Listed and FM Approved fire protection systems.
