Floodline Leak Detection

E&OE 06r01

Leak Detection for Damage Limitation

The Dangers

Leaks can occur in any building and are among the most frequent causes of costly damage, disruption and loss. Modern fit-out methods and the reliance on complex mechanical and electrical systems not only increase the chances of a leak, but can also make the outcome worse. The first indication of a leaking pipe hidden within a floor void may be the failure of the power supply, disruption of the network or the interruption of communications or data. Air conditioning plant, chilled water and heating systems, toilets, kitchens, vending areas, service risers, plant rooms and storage tanks can all present a serious leak hazard. If allowed to continue unchecked a leak, however small, is like a ticking time bomb! If it can be defused in time a disaster can be avoided.

The Answer

Floodline Leak Detection systems installed in critical areas will allow early action to prevent damage, reduce disruption and limit loss.

Andel's Floodline range offers the most comprehensive selection of products and systems available with a first class reputation for quality, durability, reliability and economy.

Floodline Leak detection systems suit any application, any size, any budget.

FloodlineLeak Detection Sample Zone Diagram

The diagram above demonstrates a simple example made up of various components from the FLOODLINE range of products.

A larger number of zones can be used where accuracy is important. Simple, single zones can be used when only a general alarm is required.

Where possible, e.g. the computer room, detection cable can be targeted at specific items such as the A/C units and supply pipes. In other areas regular patterns of detection cable will give general coverage.

Point sensors are used on solid floors where cable would be inappropriate.

Oil sensors monitor the standby generator room or storage tank bunds for oil leaks.

Overhead pipes can be protected by super-sensitive Multi-4 4 zone detection cable or Single Zone Tape.

Apartments


Case Study 3:Apartments

Installation:Floodline LeakDetection System

Leak detection is now being fitted to more andmore multi-occupancy apartment blocks andindustrial conversions to protect from leakingpipework, bathrooms, kitchens and waterheaters.

Floodline Leak Detection equipment wasrecently installed at the award winningVictoria Mills complex in Shipley, WestYorkshire monitoring all wet services withinthe building.

When old buildings are converted into up-market apartments, new hot and coldwater services are installed for each apart-ment. Bathrooms, W/C’s, Kitchens and WaterHeaters - all potential leak sources.

Many refurbishment designs includesuspended floors with water, electric and gasservices within the floor void.

Without some form of alarm the first sign of aleak in an upper apartment will be watercascading into the premises below. Left tocontinue for any length of time this can causeserious damage, major upheaval and alsovery expensive compensation claims.

Systems can be installed within the floor voiddirectly beneath the water services pipework,bathrooms, kitchens etc. If needed each areacan be allocated it’s own zone.

Each Apartment can have it’s own localFloodline One Zone Control Panel, or a wholebuilding can be monitored by a centrallylocated Floodline Multi - Zone Control Panel.

“People paying a fortune for a classyapartment do not expect to be affected by thecarelessness of residents above. A flood is adisaster and usually results in legal action.Leak detection is a “must” to ensure we arecovered.”

Data Centres, Exchanges and Switch Centres provide a critical service relied upon by millions of subscribers in their day to day business and life. Continuity of service is not only essential to users but also vital in terms of revenue to their operators. The owners, operators and designers of these high-tech installations are naturally concerned to protect themselves from all potential damage and water leakage detection is now part of the standard monitoring and alarm package.

Andel’s Floodline leak detection systems are chosen as the best, most reliable and cost-effective option by many of the world’s most prestigious “blue-chip” organisations. In the UK companies such as BT, HSBC, Orange, Global Switch, ICM Group, Airbus Industries, Norwich Union, GSK, National Grid and many others are regular end users of Floodline systems.

Data or communications centres are built to the latest designs employing up to the minute features and technologies. Mile upon mile of data, network and power cable is installed under raised access floors where it can be organised and routed safely out of sight. The problem is that this void also contains water service pipes feeding A/C units, toilets, kitchens etc. The unsightly cables and pipes may be hidden from view – but so are the problems!

Leak detection equipment is installed in floor voids to monitor chilled water pipes and condensate drains for the A/C and fan coil units, hot and cold water for the toilets, vending and tea areas etc.

Special detection cable or pad and point sensors are installed in a design or pattern to provide the best coverage. Pipe-joints and connections are particularly sensitive so sensors are clipped to the floor directly around the ‘footprint’ of each unit or beneath the whole length of pipe work. Point sensors can be targeted at specific items or areas. In the event of a leak being detected an early warning is given BEFORE damage can occur.

Where pipes run at high level or there are roof valley gutters and down pipes, drip trays are suspended below pipes and gutters with leak detection cable running the entire length or point sensors installed at a low end.

The leak detection system will be zoned to allow quick and accurate location of the leak. Each A/C unit is allocated a separate ‘Zone’ and runs of water pipe are sub-divided into a number of ‘Zones’ usually 5-10m in length to help isolate the leak to a convenient length.

Point sensors are installed in plant rooms with solid floors to monitor for a build-up or ‘pooling’ of water from leaking equipment, water tanks, booster sets and pumps etc.

Other areas of concern are toilets, tea points, vending machines, water fountains, kitchens and also services risers.

All areas are monitored either by individual local Floodline Control Panels or a centrally located Floodline Control Panel. Options include small, stand–alone systems or larger multi–zone control panels. All Floodline systems provide connections for the BMS or other remote monitoring via volt-free contacts or RS232/485 communication protocols.

Historic Buildings and Royal Palaces


Case Study 2:HistoricBuildings


Andel’s award winning Floodline LeakDetection equipment has been installed inmany historic and heritage buildings such asWindsor Castle, Houses of Parliament,Buckingham Palace, Marlborough House, St.James Palace, Peterhouse College and theBritish Library to protect against potentiallydamaging leaks from water services.

Due to the design of older historic & heritagebuildings, services such as heating & coolingpipework and plantrooms may have beeninstalled in a seemingly haphazard way.

Water Leak Detection systems are ofteninstalled within these buildings to protect theactual fabric & structure of the building, i.e. ornate ceilings, walls and floors etc., aswell as offering protection and an earlywarning before major damage is caused tovaluable and even priceless antiques andworks of art displayed within the building.

The very nature of these buildings makes theinstallation of any modern systems difficult.The flexibility of the Floodline system, its widerange of sensors and the ability to make it asunobtrusive as possible makes Floodline idealfor these types of buildings.

Floodline Control Panels are installed to suitthe application, either small stand-alone

Single Zone systems, or much larger Multi -Zone Control Panels, offering the capabilityfor reporting back to central BMS monitoringsystems using either volt-free contacts orRS232/485 Comms.

“We have a duty to care for and protect thebuildings in our charge. By their very naturehistoric buildings often have historic serviceswithin them. The Floodline leak detectioninstalled in critical areas has proved it’sworth more than once.”

Museums and Art Galleries


Case Study 1:Museums and Art Galleries


Andel’s award winning Floodline LeakDetection equipment has been installed inmany Art Galleries and Museums such asTate (Britain & Modern), British Museum(Great Court), Manchester Museum and theNational Museum of Scotland to protectagainst potentially damaging leaks from water services.

Due to the design of older historic & heritagebuildings, services such as heating & coolingpipework are difficult to maintain and therefore cannot be protected against seriousor damaging leaks.

Water Leak Detection systems are ofteninstalled within these buildings to protect theactual fabric & structure of the building, i.e. ornate ceilings, walls and floors etc., aswell as offering protection and an earlywarning before major damage is caused tovaluable and even priceless antiques andworks of art displayed within the building.

Most often plant rooms, roof spaces andbasements are considered to be the principalsources of leaks in these types of buildings.

Floodline point sensors are usually used here.Detection cable can be applied directly topipes or run on, or behind, display cabinets.

Floodline Control Panels are installed to suitthe application, either small stand-alone

Single Zone systems, or much larger Multi -Zone Control Panels, offering the capability forreporting back to central BMS monitoring systems using either volt-free contacts orRS232/485 Comms.

“The Floodline system has saved us on several occasions. I hate to think what wouldhave happened without it.”

Curator, Major National Art Collection

As part of BS EN378 Andel have supplied and installed a major refrigerant gas detection system across 7 floors of a new London office block monitoring all Air conditioning units and associated pipework for any leaks within office areas and alerting staff with both local and centralised alarms.

BS EN378 specifies the installation of fixed refrigerant leak detectors in both existing and new systems especially where there is more than 300kg of refrigerant within the system.

The Floodline FGS1000 complies with BS EN378 and detects refrigerant gases to H S E Occupational Exposure Limits. The sensitivity controls are calibrated with 1000ppm gas to air mixture using the specified gas (R134A, R404A, R407C, R410A). Other gases can be accommodated subject to calibration.

The FGS1000 Gas Sensor constantly monitors the area for any build up of the specific refrigerant gas above a preset level.

When a leak above the preset levels is detected, audio/visual warnings are given by a pulsing 85dB sounder along with amber LED for “LEAK” and red LED for “ALARM”.

On every floor of the 7 storey office block adjacent to A/C Units, 1no Floodline FGS1000 has been installed at 100mm above floor level, calibrated to 1000ppm of R407C refrigerant gas.

Each Sensor has been allocated its own separate Zone for ease of leak location by the client, all monitored by 1no centrally located Floodline 128 Control System.

When a leak above the preset levels is detected,

audio/visual warnings are given by a pulsing 85dB sounder along with amber LED for “LEAK” and red LED for “ALARM”. A ‘LEAK’ alarm is also shown at the central Control Panel.

Refrigerant Gas Sensors are also installed within Plant Rooms, Machine Rooms etc., and Andel have also installed an extensive Refrigerant Gas Detection system as well as a water leak detection system monitoring a major southern Data Centre.

Water leak detection is installed within the actual Data Halls and Refrigerant Gas Detection Sensors are installed in adjacent Machine Rooms & Boiler Plant Rooms.

The different Sensors are allocated separately reporting Zones with both the Water & the Refrigerant Gas Sensors being monitored by 1no central Floodline Control Panel for ease of leak location on both systems.
