UL/FM Alarm Check Valve
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.
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.
