Exclamation Water leak detection - A nightmare !!

Water leak detection system seems to be more complex and difficult to maintain in a data center. Also most of the data centers donot even have such a system in place..

Pls share your experiences and views about the same..

Best Regards,
Zhuhair.

You can buy leak testing euipment to fo find out the leaking. It will detect the water leadking.

http://www.sensistor.se

Here is some more info I got it.

Some models of leak detection systems can be connected into a home's security or fire alarm panel. If it detects water, it can send an alarm to an off site monitoring company.

Most whole house systems feature a panic switch. In an emergency, pressing a button will automatically close the detection system's water service valve. Pressing another button will reset the system.

Some of the whole house systems that use remote water sensors also have temperature sensors. If the temperature at the sensor(s) in the home drops below a specified point, the detection system will send an alarm and close the automatic shut-off valve to lessen or prevent water damage from frozen pipes.

Some control panels can identify which moisture sensor detected the leak while some can only identify that there is a leak. Knowing which moisture sensor detected a water leak will make it easier to find and repair the problem.

Just my 2 cents.

Thank you for the valuable info Jones.

Data centers primarily require a water leak detection system for identifying leaks in AC units and also in the fire sprinkler systems

I have a question here. The fire sprinkler systems use a dry-pipe, wet-pipe or a pre-action type system. In any of these cases if there is a leak in the pipes, it would be detrimental. Is the water leak detection system capable of identifying and alerting proactively..? Also, what is the cost of such systems..

Pls share your experiences on the same..

Best Regards,
Zhuhair.

No problem, NOrmally use pre-action type system. Yes it will detect provide you the level of leaking. So you can take the action right a way. System prices can be various you make be looking between 2K -5K.

Here is another system that a lot of data centers use. It is a rope and it can tell you which foot has the water. You can zip tie it to overflow or drain pipes.

Hi all, I am OEM for WLD systems , my company is TTK UK Ltd..- TTK, we protect heritage structures like Louvre Musuem and work with most blue chip DCs in EMEA region, clients include JPM, Morgan Stanley, Merill Lynch, IBM centers. Our sense cables are 8 core and have processors embedded on them, thus we can locate exact location of fault , each sense cable is addressable. Since water needs to perculate inside and physically touch a well meshed Cu filament false alarms are not possible. We are UL listed product. We also are only manufacturer to give simultaneous faults and also indicate the exact location of leak and cable break if any. Please write to me at vdeshpande@ttkindia.com should you need further info.
Best regards

Default Fire Suppression Systems...

I am very picky about our fire suppression and detection system. We use a predictive air sampling system in combination with a zoned NOVEC 1230 in pod approach. For the high performance clusters with reversed air flow and cold aisle containment, we use a in rack approach.
The air sampling needs a certain amount of time to adjust to your environment, but it works great and can predict hardware failure actually days ahead..
The NOVEC 1230 advantage is... you wont die!
