Flow Test Assemblies

Flow Test Assemblies

Our Flow Test Assembly is designed for use where sprinkler systems are divided into zones, for example shop units or high rise buildings. The unit is supplied with grooved pipe work and all electrical wiring for quick installation on site.

The Potter flow switch detects the flow of water as a result of a sprinkler head activating; this in turn sends a signal to an alarm panel, to indicate which zone has been activated.

Each unit comes complete with a monitored butterfly valve, which can be used to isolate a zone for maintenance or testing.

The drain valve is used to drain the water from each zone, or to stimulate a sprinkler activating, for test purposes.
