Combining our industry standard remote flow-switch tester, Zonecheck, with a local monitored zone valve as a fully pre-wired unit rapidly speeds up installation and testing.
Sprinkler zones require a flow-switch and an isolation (zone) valve and these two items are normally installed next to next to each other. To further save on labour and installation time, Zonecheck V combines our approved flow-switch testing device, Zonecheck, with an approved monitored butterfly valve. These two items come pre-assembled and pre-wired meaning that the sprinkler contractor can install, commission and test both the flow-switch and the isolation valve reducing the overall installation time.
Key-switch
We have re-designed our key-switch to include a new monitoring function for a local valve. The new key-switch now detects whether a connected monitored valve is left in the correct position. Electrical engineers can then take an additional fire signal from the flow-switch and an additional fault signal from the monitored valve onwards to a centralised alarm system.
System
Benefits
Zonecheck V reduces the amount of time spent on-site with rapid installation of sprinkler zone equipment.
The pre-wired unit is pressure tested with water and all fully electrically tested ready for commissioning.
The new key-switch provides a remote alarm, monitoring for the correct position of the valve.
Saves water, energy and labour reducing the carbon footprint and cost of managing a sprinkler system.
All managed components stay fully code compliant. Full pass/fail test and event log provided.
Easily integrated into a building’s fire alarm system or BMS.
Pre-wired & Tested
Factory assembly provides consistency, accuracy and the ability to factory test units, which increase assurance and dependability once installed on site.
Zonecheck V comes fully pre-wired. The key-switch is wired to the flow-switch, pump and monitored valve via male/female connectors and is supplied with a commissioning lead. This means that the unit can be fully functionally tested and commissioned in advance of fire and fault signals being connected to a centralised system.
Approvals
Zonecheck is fully approved to LPCB, UL, VdS and FM standards. Our standard unit comes with an LPCB, VdS, UL and FM approved Victaulic Firelock 705 monitored butterfly valve.

Frequently asked questions
What is Zonecheck V?
Sprinkler zones always require a water flow detector (typically a flow-switch) and an isolation valve (typically a monitored butterfly valve) and these two items are normally installed next to next to each other. To further save on labour and installation time, Zonecheck V combines our approved flow-switch testing device, Zonecheck, with an approved monitored butterfly valve. These two items come pre-assembled and pre-wired meaning that the sprinkler contractor can install, commission and demonstrate the correct function of both the flow-switch and the isolation valve more quickly.
Is Zonecheck V pre-wired?
Yes, Zonecheck V comes fully pre-wired. The key-switch is wired to the flow-switch, pump and monitored valve via male/female connectors and is supplied with a commissioning lead. This means that the unit can be fully functionally tested and commissioned in advance of fire and fault signals being connected to a centralised system.
How do I activate a flow-switch test?
Full installation and operating instructions can be found in our instruction booklet, please ask for a copy to be emailed to you. Please note that a flow-switch test using Zonecheck will NOT discharge any water but will likely result in a fire signal being generated. To activate a flow-switch test, turn the key in the key-switch to “self test”, at this point the “Pump Running” LED should illuminate. After a brief period (up to 60s) the “flow-switch” LED should illuminate to indicate a successful test. Record the testing being completed and return the key-switch to “stand-by” mode.
How is the butterfly valve monitored?
Our key-switch (included with Zonecheck V) comes pre-wired to the flow-switch and to the monitored valve. Once the sprinkler pipework is charged with water and power is connected to the key-switch both the flow-switch and monitored valve can be commissioned, with signals on the key-switch showing correct function. Electrical engineers can then take an additional fire signal from the flow-switch and an additional fault signal from the monitored valve onwards to a centralised alarm system at a later date.
Is Zonecheck V factory tested?
Yes, the unit is pressure tested with water to 20 bar and all fully electrically tested before shipping.
Which monitored valve is supplied with Zonecheck V?
Our standard unit comes with either Victaulic Firelock 705 monitored butterfly valves (LPCB, VdS, UL and FM approved) or alternatively a Reliable REL_BFG 300 (FM and UL approved).
