Welcome to Hochiki’s Water Leak Detection System, LEAKalarm. For technical data and pricing, please visit the Hochiki online store.


The importance of finding a solution

Despite the understandably significant resources spent on mitigating loss through fire, water damage actually poses a much greater threat to business continuity. Statistics show that the most likely cause of insurance claims in hotels, retail premises and commercial buildings is water damage, costing the UK insurance market iro. £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 of around £4.5 million and Credit Card Clearance around £1.8 million.



The cost to businesses due to water leakage can be significant and it is not just the obvious physical damage to IT networks, electronic equipment, plant, fixtures & fittings, stock and the fabric of the building. Like fire damage, even a seemingly minor water leak can result in temporary relocation, loss of working hours, and loss of profits.


Hochiki have therefore developed LEAKalarm; a fully addressable, highly reliable water leak detection system, providing vast coverage and value for money.
