  • Fan Coil Leak Detector: Self-contained single zone controller & sensor which can be mounted horizontally within Fan Coil drip trays.
  • One Zone: Single zone, low cost, stand-alone control panel which can accept multiple Floodline sensors
  • Multi Zone (4-32 zones): Leak detection alarm panel suitable for small to medium projects. Includes battery back-up for mains fail
  • Floodline 128: Leak detection alarm panel suitable for medium to large projects. Includes battery back-up for mains fail
  • Andel ‘Ranger’ Sub-panel: Providing local distance measurement detection for longer areas, stand-alone or in conjunction with other FLOODLINE panels
  • As standard, all panels can be connected to any control/BMS that has the facility to accept volt-free contacts

  • Multi-4 Cable: Absorbent, sensitive sensor for critical areas. Reacts to drips. Suitable for pipe work
  • Andel ‘Ranger’ long line distance measurement sensor: Functions as a zone, suitable for longer areas up to 1500 metres, detects the presence of water at any point along its length
  • Single Zone Tape: Absorbent single zone sensor tape
  • Point Sensor: Vertically or horizontally mounted reacts to build-up / flood of water
  • Flexi-Pad: Designed for pipe joints or narrow / inaccessible areas


  • Digital DD Gas Sensors: Hydrocarbons / Methane / Propane / CO / CO2 & CFCs – Stand-alone sensor c/w audible/visual local alarm or connected to a central Digital DD Control Panel via RS485 & MODBUS RTU
  • RGD1601: All refrigerant gases detected as a stand-alone alarm system or as part of a FLOODLINE leak detection system
  • Individual calibration required per gas for all sensors


  • DP01 – Designed with DURAPIPE for use in double containment pipe work systems. Optical sensor fitting into interstitial gap
  • Oil Sensor: An optical sensor used in oil tank bunds, generator rooms & trenches
  • Available in vertical or horizontal configuration, multiple re-use, wipe clean & return to use


  • Breeameter®: Incoming mains water monitoring for underground pipe leaks in accordance* with BREEAM WAT02 / WAT03
  • Controller plus 2no flow meters
    *not affiliated, endorsed or certified by BRE Global Ltd


  • Solenoid Valve Panels: Dedicated solenoid valve control panels to turn off water supply if leak detected, preventing greater damage
