Zone check Testing Device

The unique ZONECHECK system is the modern way to carry out this important test quickly, efficiently and inexpensively.

Installing ZONECHECK creates a closed loop Flow Switch Test circuit:

ZONECHECK simply re-circulates the existing water around the Flow Switch (irrespective of the static pressure), creating a closed system with no water discharge.

This pressure difference across the flow switch generates a water flow causing the Flow Switch to operate.

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.

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 flow switch test can be difficult, time consuming and costly. For these, and other reasons it is often ignored and the Fire Certificate and Fire Precautions (Workplace ) Regulations 1999 are contravened.

When a Fire Certificate is issued for Sprinkler protected premises, it stipulates that the system must be maintained and tested to the British Standard. Currently this is BS 5306 Part 2. These rules make the quarterly flow switch test mandatory.
