ZoneCheck is a world wide patented product that provides a closed loop system to re-circulate water around the Flow Switch to simulate one sprinkler head in operation without the need to discharge any water from the system.
AS1851 requires Flow Switches installed in a sprinkler system to be tested 6 monthly, (FM Global requires this test monthly). During a traditional Flow Switch test, water is discharged from the down stream end of the pipe. This pressure difference across the Flow Switch generates a water flow causing the flow switch to operate. The unique ZoneCheck system is the modern way to carry out this important test quickly, efficiently and inexpensively with zero water wastage.
ZoneCheck provides a true and accurate test of the Flow Switch and compared with a traditional test solenoid/drain arrangement saves up to 300 litres of water per test (dependent on Flow Switch retard setting). The ZoneCheck pump has a flow control orifice which accurately represents just one sprinkler head in operation, irrespective of current system pressure, which is the only true way to test the effective operation of a Flow Switch with one sprinkler head operating.
As no water is discharged from the system, the system pressure remains unchanged, therefore no fire pumps operate and there is no need to perform pressure switch/brigade isolations or recharge the system before during or after the tests. This makes testing a much simpler process than any other method so tests can easily be performed on a more regular basis with no system interruption while ensuring correct system operation at all times.
ZoneCheck is simple and easy to install and comes as a complete pressure tested unit with pump, Flow Switch, and pipe with rolled groove ends for ease of installation. Retrofit and LiveTap versions are also available for existing installations.
