How is it used?

The monitor is deployed directly at the scene and connected to a 2.5" water supply line. Once in position, the operator adjusts elevation and rotation to direct the stream, then opens the valve to deliver high-flow water or foam for structural firefighting applications.

Who used it?

The Mercury Quick Attack Monitor is used by firefighting professionals involved in structural firefighting operations who require a portable, high-performance monitor that can be quickly deployed and repositioned as conditions change.

Maintenance Information

Routine maintenance involves inspecting the valve, handle, and inlet and outlet connections for wear or debris, ensuring smooth movement of elevation and rotation components, and verifying that all seals and fittings remain in good condition.

Storage Information

When not in use, the monitor can be stored using the attached strap and bag. It should be kept in a clean, dry environment to help preserve materials and maintain reliable performance.
