Water leak detection controller with sensing rope. Complete detection system for data centres, server rooms, and facilities. Relay alarm output, multiple zone support.
Our water leak detection controller paired with sensing rope provides a complete, ready-to-install leak monitoring system for data centres, server rooms, telecommunications rooms, and critical facilities. The controller continuously monitors the sensing rope resistance and triggers a relay alarm output (NO/NC) when water is detected -- enabling integration with BMS, SCADA, or local alarm panels. LED or LCD status display provides at-a-glance system health.

Yes. The relay output (NO/NC) can trigger any BMS or SCADA dry-contact input. Models with RS-485/Modbus RTU communication can be polled by SCADA systems for real-time status. Contact us to specify the communication protocol you require.
Single-zone controllers monitor one rope loop. Multi-zone controllers (4--8 zones) can monitor multiple independent rope circuits simultaneously, enabling coverage of multiple rooms or areas from a single controller. Each zone can have up to 200 m of sensing rope.
The controller uses a supervised circuit (4-wire connection with end-of-line resistor). A broken or disconnected rope generates a "fault" alarm distinct from a water detection alarm, preventing the system from silently losing coverage due to a wiring fault.
