ZoneCheck is a remote flow-switch testing device. It works by using a closed loop system that
re-circulates water to simulate sprinkler head operation and tests the flow-switch without discharging water. 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.
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.
