2Product Overview
Ensure you have read the Safety Information in section 1 before attempting installation or
operation of this unit.
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), and
Main Equipment Rooms (MERs).
The unit may also be configured. 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.
Features
Capacitive touch interface
User configurable (sensitivity adjustment,
alarm delays, output control, overrides, and
self-maintenance features)
Multiple outputs
Pattress or flush mountable; mains powered
Audible and visual alarms
Compatible with a large number of sensor
types and ancillary devices
CE Compliant
Operation
In operation, the EMS-01 continuously monitors the sensing equipment connected to it for both circuit integrity
and the presence of water. 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. Benefits of the EMS-01 include:
Continuous leak and cable break monitoring
Minimal human intervention required
Reduced risks from flooding
Built-in fault detection
EMS Series Models
In addition to the EMS-01, the Aqualeak EMS series also includes the following models:
EMS-05
5 input channels
EMS-10
10 input channels
EMS-OS
Multiple input channels (scalable and
modular for large scale applications, up to
620 zones)
