Aqualeak EMS-5/10

multizone water leak detection system

The Aqualeak Environmental Monitoring System (EMS) Water Leak Detection System series are standalone leak detection systems designed to be capable of integrating into larger Building Management Systems (BMS) and networks, as required.

Designed for continuous operation with minimal human intervention, the EMS series is also compatible with a wide variety of sensing technologies (sold separately) to detect the presence of water and other liquids.

With 5 (EMS-5) or 10 (EMS-10) input channels as standard, the models are ideal for applications ranging from Data Centres, Main Equipment Rooms (MERs), Plant Rooms and Comms/Server Rooms.

This cost-effective multi-zone solution also requires no configuration for ease of installation and operation.
