The Hydrosense Water Detection System is designed to protect areas where water leakage could seriously damage electrical, communication and computer networks. When installed in vulnerable areas it continuously monitors for water leaks.
Hydrosense can be installed in a wide range of applications including HVAC, sprinkler systems and water-cooled plant.

A Hydrosense System has two methods of leak or moisture detection, Linear or Point detection.
Linear detection is provided by Hydrowire moisture sensitive cables, which are connected to the control panel via a special Connection Box using a simple two core leader cable, making installation quick and inexpensive.
Available as standard 5 and 10 metre lengths pre-terminated with DIN plugs, 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. Hydrowire will dry out in around 20 minutes for use again. Each zone requires a junction box and an end of line plug. For areas where continuous detection is not required zone breaker cables are available.
Point detection is provided by Floor, Drip Tray Probes and Float Switches – all connected to the control panel by simple two core leader cable. The Floor Probe is fixed to the floor and adjusted to give the required detection level and connected to the control panel via a junction box. The Drip Tray Probe has exactly the same facilities as the Floor Probe but has a bracket for mounting onto the side of an ACU drip tray. The Float Switch alarm is for use in sump pumps, basements, etc.
The Hydrowire and Probes are continuously monitored. Any disconnection or fault is immediately indicated on the control panel. All monitoring indicators can be repeated to remote repeater panels or via volt free contacts to a building management system. When an alarm is raised, Fire-Cryer® voice sounders can be used to broadcast an unambiguous message, avoiding confusion with other sounders on site.
The Hydrosense system has a range of attractive and unobtrusive control panels containing the alarm circuitry, power supply and has the facility for 24 hour battery standby. Two types of control panel are available. The Hydrosense HSCP is available in 2, 4 and 8 Zone configurations and the Hydrosense K200000 range for 12 Zones or greater. Flush versions and special finishes are also available.
Repeater panels and ancillary PCBs are available to provide common alarm, common fault, coincidence and zonal alarm, VFCs allowing control of sub-systems, graphical mimics and plant, remotely from the main panel over a two wire data bus.
