2Product Overview
The EMS-05 supports both RS232/RS485 protocols. RS485 is the default protocol and an Aqualeak
Engineer will be required if RS232 is required.
The Aqualeak Environmental Monitoring System (EMS)
Water Leak Detection System series are standalone leak
detection systems designed to be integrated with 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.
With 5 (EMS-5X) or 10 (EMS-10X) input channels as standard,
these models are ideal for applications ranging from small
multi-room offices to medium-sized industrial and
commercial complexes. Alternatively, the scalable and
modular EMS-OS is ideal for large scale industrial and
commercial applications.
Features
Highly versatile with bespoke configuration
Programmable relay outputs
Remote Status Monitoring (via email)
Email, Modbus and multiple digital outputs
Supports Modbus TCP/IP and Modbus RTU
RS232/RS485
Touch screen display
Designed and built in the United Kingdom
CE Compliant
Monitors for leaks, sensor cable breaks and
internal system faults
Operation
In operation, the EMS-05 continuously monitors all independent sensing circuits connected to it to reduce risks
from flooding. If a leak or cable break is detected, the EMS-05 will and/or can be configured to:
Activate a visual alarm
Activate an audible alarm
Shut off local water supplies
Activate default and user-defined outputs
Report to any network via Modbus, digital
output, and/or email

3Installation
Risk of electric shock and equipment damage! Ensure you have read section 1 Safety Information
before attempting installation.
3.1 Master Panel Installation
3.1.1 Mounting
The Master Panel has knock-outs for electrical cables on the top, bottom and lower rear of its
enclosure.
Mount the Master Panel as follows:
1. Ensure the Master Panel has been properly
removed from its packaging.
2. Securely mount the Master Panel in a
suitable location, making cable entries as
required.
3. Bring the cables through into the Master
Panel before starting to make final
connections
3.1.2 Power Connection
A competent person must install a 230 VAC unswitched fused spur near to the EMS. The switched
fused spur must be clearly marked as the disconnecting device for the EMS. Where available, the
EMS unit should be connected to a UPS-backed power supply.
Figure 5: Master Panel Electrical Power Connections
Connect power to the EMS as follows:
1. Route the power cable from the
unswitched fused spur into the Master
Panel through a suitable containment or
cable protection method.
2. Connect the power cable (i.e. Live, Neutral
and Earth) to the Master Panel mains cable
input terminal (Figure 5).

3.2 Relays and Sensors
Although multiple sensors and sensor types may be connected to the unit, there must always be
an end of line (EOL) terminating resistor at the end of the sensing circuit to allow for cable break
monitoring and alarm reference set point. The unit relies upon a terminating resistor of value
47k ohms.
The unit should be powered OFF when making connections. Sensors should be installed so that they remain
accessible for maintenance.

3.2.2 Reboot Relay
The reboot relay switch SW1 must be returned to the OFF position when testing of or updates
to the EMS have been completed.
Power to the TFT LCD Touch Screen Computer is supplied via a re-boot relay. If communications between
the Motherboard and the touch screen are lost for more than 60 seconds, this relay will operate to re-boot
the computer.
This function can be bypassed by switch SW1 for testing purposes or when updating the EMS software. When
the switch is in the OFF position the relay is bypassed and power is permanently supplied to the touch
screen.

3.3.3 230V Output to Ancillary Device
The EMS can be used to control a powered ancillary device such as beacons or solenoid valves.
Maximum demand of all connected ancillary devices will be governed by the supply fuse in the
unswitched spur and cable of a suitable cross-sectional area should be used.
Figure 13:Using the EMS to Power a 230V Ancillary Device (Normally Closed)
Figure 14:Using the EMS to Power a 230V Ancillary Device (Normally Open)
Use the EMS to power a 230V ancillary device as follows:
1. Refer to Table 3 (3.2.1 Relay Functions
and Triggers) to select the correct relay.
2. Wire the device (Figure 13 and Figure 14).
If the device is not within the immediate
vicinity of the EMS panel, a local isolator
must be installed next to the device for
safe isolation and maintenance. The fuse
rating of the local isolator should be less
than that in the supply spur for circuit
discrimination.
