Aqualeak EMS-5/10

ems-01 water leak sensor alarm panel from aqualeak

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

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.

The Aqualeak EMS-01 is designed to monitor for water leaks in single-zone critical areas such as Tea Points, Satellite Equipment Rooms (SERs), Main Equipment Rooms (MERs) and Server Rooms.

Sensitivity to moisture and delays to alarms may be adjusted to better tailor the system to intelligently respond to a wide range of environments, situations and user requirements.

If a leak is detected, an audible alarm is activated, an LED illuminated, and, if connected, the EMS will report its alarm status to any connected device (BMS/SMS/beacon, valve) via its volt free contacts.
