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 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-5) or 10 (EMS-10) input channels as standard, these
models are ideal for applications ranging from small multi-room
offices to medium-sized industrial and commercial complexes.
Our most affordable and cost-effective solution also requires
no configuration for ease of installation and operation.
Features
Affordable
No configuration required –works straight
‘out of the box’
Easy operation
Designed and built in the United Kingdom
CE Compliant
Monitors for leaks, sensor cable breaks, and
internal system faults
Operation
In operation, the EMS-5/10 continuously monitors all independent sensing circuits connected to it to reduce
risks from flooding. If a leak or cable break is detected, the EMS-5/10 will and/or can be configured to:
Activate a visual alarm
Activate an audible alarm
Activate default outputs

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 4: 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 4).

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.

3.3 Ancillary Devices
3.3.1 Signalling to Ancillary Device
The EMS can be connected to provide a signal to a range of ancillary devices such as a Building
Management System (BMS) or Short Message Service (SMS) alarm unit.
Figure 10:Connection of Master Panel for Signalling to an Ancillary Device
Connect the EMS Master Panel to an ancillary device as follows:
1. Ensure that the unit is powered OFF. Refer
to Table 3 (3.2.1 Relay Functions and
Triggers) to select the correct relay for the
application.
2. Connect to the relevant relay (Figure 10;
core colours are for illustrative purposes
only and may differ during application).
3.3.2 12/24V Output to Ancillary Device
Figure 11:Using the 12/14 Output to Power an Ancillary Device
Use the 12/24V auxiliary output to power an ancillary device as follows:
1. Ensure that the unit is powered OFF. Use
the voltage selector switch SW2
(Figure 11)to set the output to the correct
voltage for your device.
2. Connect your device to the 12/24V output
(Figure 11).

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 12:Using the EMS to Power a 230V Ancillary Device (Normally Closed)
Figure 13: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 12 and Figure 13).
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 off
that in the supply spur for circuit
discrimination.
