How Zonecheck Works -
The Zonecheck solution is simply to connect a pump to
either side of the flow switch to create a loop, then by
switching on the pump, an artificial pressure difference
can be created across the flow switch. This in turn
generates a water flow around the loop, causing the flow
switch to operate, but this time without any loss of water
from the system.
In a standard flow switch test, water is discharged from
the sprinkler system to create a flow past the flow switch
causing it to operate.
Zonecheck Simply re-circulates the existing water around
the flow switch (irrespective of the static pressure),
creating a closed system with no water discharge.

The Automatic Flow Switch Test System
| Zonecheck® |
Zonecheck -
A closed loop system that re-circulates water to simulate sprinkler head operation and tests the flow switch without
discharging water.
Flow-switches installed in a sprinkler system are required to be tested on a quarterly basis, and for that test to be valid,
sufficient water must pass the Flow-Switch to activate it, (equal to one Sprinkler head in operation)
Prior to a conventional routine test, the pressure on both sides of the Flow Switch is equal, maintaining an equilibrium
with no water flowing.
During a routine test, water is discharged from the Down Stream end of the pipe, causing a drop in the pressure.
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.
Zonecheck ® simplifies testing by re-circulating the water within the pipe around the flow switch, to simulate the flow of
the sprinkler head in operation.
