BellCheck is an automatic alarm valve test system that significantly reduces water wastage when undertaking mandatory weekly tests on automatic alarm valves in order to comply with AS1851-2005.
The only water used with the BellCheck system is the water required to test the alarm gong. This results in a water saving of over 90% compared to the traditional method.
BellCheck is the only approved system designed to simulate exactly one sprinkler head in operation, with no excessive flow condition, regardless of the actual operating pressures of the sprinkler installation.
The practical benefit of BellCheck, over and above code compliance, is to accurately ensure that in the event of discharge of just one sprinkler head that the building owner can be 100% sure that the sprinkler alarm valve will activate.
By the simple operation of a key switch, the BellCheck pump re-circulates water from above the alarm valve to the underside of the alarm valve causing the alarm valve to lift simulating the exact operation of one sprinkler head without discharging water from the system to drain.
This can result in a saving of up to 9,100L of water per year / valve set on weekly testing.
