Hydrosense Water Detection System

Delivering a New Standard in Water Leak Detection

The Problem

Despite the understandably significant resources spent on mitigating loss through fire, there is a much greater threat to business continuity, that of disruption to business and asset damage through water leaks.

Statistics show that the most likely cause of claims in blocks of flats, hotels, retail premises and commercial buildings is water damage. It is now a commonly accepted fact by UK insurers that water leakage is now the costliest and most common claim made by commercial customers with a total loss in the UK alone approaching £800 million.

The financial market is particularly sensitive to these potential losses with Data Centre outages costing such businesses an average of £12,000 per minute, hourly losses on the Stock Exchange around £4.5 million and Credit Card Clearance around £1.8 million. The cost to businesses due to water leakage can therefore be significant and it is not just the obvious cost of physical damage to IT and other electronic equipment, plant, fixtures and fittings, stock and the fabric of the building. Like fire damage, even a seemingly minor water leak can result in temporary relocation, resultant increased employment costs and significant business interruption and loss of profits.

The Solution

Hydrosense Products

The only way to mitigate the risk of water damage is to continuously monitor for water leaks. Risk assessment of the risk of water damage and the installation of Water Leak Detection Systems are increasingly being recommended by commercial insurers and is often a requirement for full cover.

Leading the way in Water Detection technology is the new ‘Hydrosense’ system from Vimpex, it includes both Conventional and Addressable solutions and designed to be infinitely reliable, with many of its features also found in systems designed to ensure life safety.

How it Works

Hydrosense leak detection systems are designed to protect areas where water ingress could seriously damage electrical, communication and computer networks. It continuously monitors for water leaks around the clock, year in year out and has the facility for 72 hour battery standby in the event of power failure. Should a leak be detected the control panel sounds an alarm which can be extended to a remote location. When an alarm is raised, Hydro-Cryer® voice sounders can be used to broadcast an unambiguous message, avoiding confusion with other sounders on site.

The new Hydrosense systems provide both linear detection using Hydrowire and point detection using probes. Linear detection Hydrowire is a flexible cable which will continuously monitor large areas. When even a small amount of water or moisture comes into contact with Hydrowire it will trigger an alarm. Point detection is provided by Hydrosense floor or drip tray probes, these are fixed to the floor or drip tray and adjusted to give the required detection level and connected to the control panel via a Hydrosense water leak detection module.

Utilising life safety technology in the design of Hydrosense provides the reliability and integrity of BSi approved fire detection systems, meaning there is virtually no risk of failure, downtime and significantly fewer false alarms.
