Designed specifically to fully comply with BREEAM WAT02 and WAT03 assessment criteria for water monitoring and leak detection, the Series 7 system will detect any minor and major water leak from both the site boundary and internally within the building.

This system will identify different flow levels using a pulse sensor sent to the control panel after every 1 or 10 litres of water flow, identifying leakage rates, e.g. continuous, high and/or low level, over set time periods with a self-learning audit function which monitors normal consumption. Install internally as a single channel system for WATO2 BREEAM compliance or with an additional boundary water meter for BREAM WAT03 identifying leaks both internally and from the site boundary.

Multiple isolation valves can be added to protect against the damage and disruption caused by leaks. Although not a requirement of BREEAM isolation valves are essential to mitigate the risk of water damage during the construction phase for CIREG compliance.

The controller is completely adaptable to suite the user’s requirements and water usage ensuring its functionality in an occupied environment.

Adjustable Parameters

The Series 7 can analyse water usage by volume per ½ hour, hour, guard period or 24-hour period. The system has two separate menus for perimeter setting and day to day operation, the Guard and the Engineer menu. The Guard Menu is used to input user specific requirements as below:

  • Maximum litre allowances in each guard period or per 24 hours.
  • Maximum override time.
  • Guard mode to suit buildings timetable.
  • The building timetable

Features and Benefits

  • Activated when the flow of water passing through the water meter is at a flow rate above a pre-set maximum for a pre-set time.
  • Able to identify different flow and therefore leakage rates.
  • Available for pipe sizes 15mm to 200mm.
  • 12V DC and 230V AC versions available.
  • Full events log for checking detailed activity.
  • Fully programmable to suit the owner/occupiers’ water consumption criteria.
  • Practical access to the controls without the need to dismantle when making setting adjustments.
  • Designed with an override function to avoid false alarms caused by normal operation of large water-consumption.
  • Schedule up to 3 manual overrides per day allowing up to 120 minutes of unlimited water.
  • Audible and visible alarm when activated by a detected leak.
  • An integrated back-up battery will continue to power the controller in the event of a mains power loss.
  • Power warning options: Mains fail, low battery, both, or none.
  • Available with or without automatic shut off valves, valve requirement dependent on application.
  • Manually operate valves from the control panel.
  • Connect to two valves as standard, unlimited valves can be connected.
  • Compatible with water meters with pulsed outputs of 1, 10 & 100 Litres per pulse.
  • Meter readings visible from the controller with comparison data to show water going to ground when a boundary meter is connected.
  • Output link available to BMS.
  • Input link available to alarm system for automatic guard switching.
  • Option to automatically switch guard level to high after 25 hours of no water use.
  • Automatic audit function records maximum litres of water used in high and low guard periods.
  • Audit can be used to automatically set system parameters.
  • Option to automatically shut off water supplies automatically outside operational hours.
  • Connection available to booster/header tanks and pumps to isolate power in the event of a leak.
  • Optional Waterguard Pulse Splitter allowing an additional pulse count to be sent to the BMS.
  • Use in conjunction with the Waterguard PIR systems to isolate the water supply in frequented toilets and wet areas for maximum BREEAM credit
