UL/FM Alarm Check Valve

The Wall Type Indicator Post (Models MH-1510FA/MH-1510A) is a UL/FM-approved wall-mounted fire hydrant system, designed for reliable water supply in commercial, industrial, and urban public spaces—supporting fire truck and hose connection for efficient fire suppression.

UL FM Fire Alarm Check Valve is a critical supervisory device installed on a fire sprinkler system. It's not one single object, but rather a system component with a specific purpose and certification.
