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).
The unique Zonecheck system is the modern way to carry out this
important test quickly, efficiently and inexpensively with dramatic
water savings makes using Zonecheck the obvious choice for performing
the quarterly flow-switch test.
Zonecheck simplifies testing by re-circulating the water within the
pipe around the flow switch, to simulate the flow of one sprinkler head
in operation, regardless of where the Zonecheck is installed or located
on the system.
Zonecheck is simple and easy to use, requiring no specialist skills
and this flow-switch test system can be operated at any time. It does
not require evacuation of the building and therefore has no effect on
normal functioning of the building.
How it Works
The Zonecheck solution is simply to connect a pump and create a loop
around the water-flow detector, then by switching on the pump, an
artificial pressure difference can be created across the water-flow
detector. This in turn generates a water flow around the loop, causing
the water-flow detector to operate, but this time without any loss of
water from the system.
In a standard test, water is discharged from the sprinkler system to
create a flow past the water-flow detector causing it to operate.
Zonecheck simply re-circulates the existing water and the water-flow
detector (irrespective of the static pressure) using a closed system
with no water discharge..

Green Testing
|
For a building with fifty flow-switches carrying out a quarterly
test, Zonecheck will save 64,000 liters of drinking water annually.
Thats over 3 million liters of water over the buildings life cycle!
Not only is Zonecheck green but it can also save building owners
money. Traditional testing methods are difficult, labour intensive and
costly requiring two sprinkler engineers to perform a test. Zonecheck
can do all this remotely with a turn of a key requiring no specialist
skills.

Sustainability in Fire Protection

100% Water Saving
With Zonecheck there is no unnecessary discharge of water. Typically
with 4 tests required per annum, Zonecheck saves 1280 liters of water
per annum for each water-flow detector that is installed. As water is
not replaced during testing, pipe corrosion is also reduced.
Increased energy efficiency and lower costs
Testing normally requires the fire pumps to operated and manually
switched of after each test. Zonecheck creates a closed loop test
circuit so that fire pumps are not required to operate. With Zonecheck,
as no water is discharged, testing is easy, takes less time and requires
no additional manpower.
Reduced life cycle carbon footprint
Testing with Zonecheck is quicker requiring less resources (water,
electricity and man power) substantially reducing the carbon footprint
of maintaining a sprinkler system.
