The only certified sprinkler testing and monitoring system. 

Zonecheck Addressable is the only approved and code compliant fire sprinkler alarm, monitoring and automated testing system in the world.

Take complete control of your sprinkler system with Zonecheck Addressable, the fully approved, smart, life safety system that monitors and manages your sprinkler system remotely. It instantly notifies you of the location of any fire or faults, and fully automates your testing routine. It brings peace of mind for monitoring, testing and code compliance.

How it works

Each zone has its own Zonecheck, IMM and zone valve. The IMMs a re wired (as part of a looped system) back to the addressable controller where all of the Zonechecks and local zone valves (or external fire equipment) in the loop are monitored. In the event of a fire, the exact location of the first flow-switch to activate is dis played on screen. The information received by the controller can then be relayed to a building's main fire alarm panel, Building Management Systems or other compatible devices.

During testing, a 'test' command is transmitted via the looped system to the IMM(s). Each IMM operates its local Zonecheck pump and monitors the flow-switch operating time. If the flow-switch operates in compliance with code standards, the IMM records a 'pass' and transmits the result back to the controller. If the flow-switch does not operate, or operates outside of the code standards required timing, the IMM records a 'fail', relays the information back to the controller and automatically turns off the pump.

The system is constantly being monitored via the IMMs, relaying status of all components installed on the loop back to the controller where an internal log of all events is stored.


The system is approved to UL 346. This means the controller, IMMs and Zonechecks are approved as an addressable system for testing and monitoring. Zonecheck is approved to LPCB, VdS, UL and FM. Zonecheck Addressable also complies with key principles of life safety codes and is compliant to BS EN 12845, BS EN 12259-5, NFPA and FM. 

Other addressable systems are fabricated on-site and are not approved to any standards.
