LEAKtrace is Hochiki's conventional water leak detection system — a straightforward, reliable solution built for installations where simplicity and ease of deployment are key.
Based around a central control panel, available in two sizes, LEAKtrace is ideal for residential properties, small buildings, plant rooms, server cupboards, commercial cellar space and any project where a fully addressable system would be more than the application requires.
Engineered with the same commitment to quality that defines every Hochiki product, LEAKtrace gives building owners and facilities managers the confidence that water leaks will be detected early — minimising the risk of damage, disruption, and costly claims.
Water damage is one of the greatest threats to property and business continuity, with UK insurers paying out close to £1 billion in claims every year. Unlike fire, the risk of an escape of water is a daily reality in almost every building — from burst pipes and appliance failures to slow leaks in ceiling voids and plant rooms. For smaller properties and sites, the consequences can be just as devastating as for large, commercial facilities.
LEAKtrace provides the early warning needed to act before damage escalates.
How does LEAKalarm help?
LEAKtrace can be connected to solenoid shut-off valves, enabling an automatic response to a detected leak and helping to limit damage from the moment of detection.
Notification devices utilise bright blue LEDs, enabling rapid and accurate visual identification of the leak location, ultimately reducing response time when it matters most. A voice sounder option is also available.
LEAKtrace supports both probe-based point detection and cable-based linear detection with both being able to be utilised within the same zone. Each zone accommodates up to 20 probes or up to 50 metres of detection cable, offering genuine flexibility across a range of environments.
Battery backup ensures LEAKtrace monitors for leaks around the clock even during a power outage so buildings remain protected at all times.
LEAKtrace is designed for fast, straightforward deployment. Its compact control panel suits small installations without the need for complex configuration or commissioning, making it ideal for installers working on straightforward projects.
Two panel sizes, Standard and a compact mini panel, ideal for small installations
Probe and/or cable detection per zone
Up to 20 probes or 50 metres of cable per zone
Blue LED per interface for fast leak location
Battery backup for continuous 24/7 operation
Compatible with remote indicators, sounders, and beacons
Solenoid valve interface for automatic shut-off
Simple installation so no complex addressing is required

Each zone has its own interface unit with blue LEDs, supporting probes (up to 20) and/or cable (up to 50m) in any combination. Both zones report back to the central panel.
The central hub of the system, receives zone signals, manages alarm and fault relays and drives outputs.
Required to power the control panel. Internal back-up batteries can keep the system running after a power failure for up to 72 hours.
Choice of voice sounder, beacon or remote indicator — all are triggered by the panel on alarm.
Panel output can be used to control external devices such as solenoid water valves, for instant water mains isolation on alarm activation.
Utilises a GSM cellular network to send real-time alerts directly to users' smartphones.
