GWD 1 - 128 Zone Sensor-based Water Leak Detector

GWD 1-128 Zone Water Leak Detector

1 to 128 Zone Water Leak Detection Systems

The GWD can offer multizone leak detection monitoring for up to 128 individual areas. The GWD is designed to detect the ingress of water in sensitive areas where high value equipment and information are present. The GWD is capable of working with a variety of detection devices including sensor cable and probes.

  • Monitors for water leaks and outputs an audio visual alarm relevant to the zone
  • Monitors for faults on the cable and can detect cable breaks and broken connections
  • Can be connected to a BMS and other devices such as solenoid valves to switch off the water

On detecting the presence of water the GWD will go into an alarm status sounding a buzzer and illuminating an LED relative to the zone where the leak is. When in alarm the relay will changeover allowing onward signalling of the event and mechanical switching of valves and pumps. Two common alarm outputs are standard however individual output relays can be used to perform a function specific to each zone.

Typical applications include archive rooms, comms rooms, computer rooms, electrical switch rooms, boiler houses, plant rooms and large data centres.

The GWD multizone system has been successfully installed in large data centres where there is a presence of chilled water.

Relay Rating: 230VAC 8 amp


Aqualeak offer a range of different sensing techniques which will allow you to tailor your leak detection system to suit your application.

These include sensor cable, sensor probes and sensor pads. The type of sensing method used depends on the environment and requirement you have for leak detection. All the sensors work on the principle that water is a conductive element and can in effect close an open circuit. Sensor range and sensor accessories details
Water Leak Detection Valve Range

Solenoid valves are available for controlling the water flow to either switch off the supply in the event of a leak, or switch it on when demanded.

Valves are available in sizes between ½” and 2” and have zero lift specification and do not require any pressure differential for them to operate.  Water Leak Detection Valve Range Details
RAA Multi Zone Remote Repeater Alarm

The RAA remote repeater can be used to repeat from 1 to 128 individual alarm panels or a multizone alarm panel connected to between 1 and 128 zones.

This remote repeater can be connected to a number of different single zone and multizone host panels around a building giving a central monitoring location. Can be used with most Aqualeak alarm panels that provide a volt free relay output. RAA Multi Zone Remote Repeater Alarm Details
Autocall Telephone Dialling Unit

The AutoCall automatic dialing system can dial out to 10 different telephone numbers and plays a voice message to inform the recipient that there is an alarm.

There are four alarm inputs and a different message can be assigned for each channel. The Autocall will work with any of the Aqualeak alarm systems via a volt free contact.  Autocall Telephone Dialling Unit Details
SMS Alarm

The SMS alarm can be used to send text messages to up to five different phones when an alarm is triggered.

Up to four different devices can be connected to the alarm inputs and a bespoke message for each transmitted. It works with any mobile network SIM card and requires no fixed telephone line to operate making it ideal for working in remote locations. SMS Alarm Details
Beacon and Sounder

When positioned on the outside of a room or on the outside of a building the beacon/sounder can be used to alert that an alarm has been triggered.

It has a very load klaxon and a bright flashing light that would be difficult to ignore even from a considerable distance away. Beacon and Sounder Details
