2Product Overview
Ensure you have read the Safety Information in section 1 before attempting installation or
operation of this unit.
The AquaGuard Dual Water Leak Detection
System is a standalone leak detection system
designed to be integrated into larger Building
Management Systems (BMS) and networks.
Designed for continuous operation with minimal
human intervention, the AquaGuard Dual is also
compatible with a wide variety of sensing
technologies (sold separately) to detect the
presence of water and other liquids.
The AquaGuard Dual is designed to monitor for
water leaks in residential and commercial
buildings. In addition, the AquaGuard Dual can
shut off the cold-water supply in the event of:
•A pipe burst
•A ruptured or fractured pipe
•Loss of power
•The property being unoccupied for longer than 24 hours
Configuring the AquaGuard Dual allows the unit to be tailored to intelligently respond to a wide range of
environments, situations and user requirements.
Features
Capacitive touch interface
User configurable (sensitivity adjustment,
output control, and self-maintenance
features)
Hardwired combined valve and flow meter
or separate valve and flow meter
Multiple outputs
Pattress or flush mountable; mains powered
Back-up battery module available
Audible and visual alarms
Compatible with a large number of sensor
types and ancillary devices
CE compliant
Operation
In operation, the AquaGuard Dual continuously monitors the sensing equipment connected to it for both circuit
integrity and the presence of water. If a leak or fault is detected, an audible alarm is activated, an LED
illuminated, and, if connected, the AquaGuard Dual will report its alarm status to any connected device
(BMS/SMS/beacon, valve) via its volt free contacts. Benefits of the AquaGuard Dual include:
Continuous leak and cable break monitoring
Automated water supply shut off
Minimal human intervention required
Reduced risks from flooding
Built-in fault detection

3Installation
Risk of electric shock and equipment damage! Ensure you have read the Safety Information in
Section 1 before attempting installation. The AquaGuard Dual can be either surface mounted with
the supplied pattress, or flush mounted (back-box not supplied).
3.1 Unit Installation
3.1.1 Mounting
Mount the unit as follows:
1. Ensure the unit has been properly removed
from its packaging.
2. Securely mount the supplied pattress box
or an appropriate flush mount alternative
in a suitable location, and make the cable
entries as required.
3. Bring the cables through the pattress box or
flush mount alternative to the unit before
starting to make final connections.
4. Securely house the unit in the pattress box
or flush mount alternative.
3.1.2 Power Connections
A competent person must power the AquaGuard Dual via an appropriate mains supply at a nominal
230V 50-60Hz, from a spur with a minimum capacity of 8 Amps. This supports switching power
to external loads through the 8 Amp Double Pole Double Throw (DPDT) relay.
Figure 3: AquaGuard Dual Rear Panel Showing Electrical Power Connections
Connect power to the AquaGuard Dual as follows:
1. Route the power cable from the
unswitched fused spur into the unit
mount, using suitable containment/cable
protection.
2. Connect the power cable (i.e. Live, Neutral
and Earth) to the unit.
