LISA, Liquid Intrusion Safe Alarming System
- Detects a drop of water
- Easy determination of the leakage location
- Alarm signal before inundation
- Self diagnostic with instant alarm for:
→Short circuit on the loop detection
→Ribbon alike sensor break off
- For protection of high cost electronic devices
- For prevention of damages due to inundation
- Suitable on any support / surface

L.I.S.A. or Liquid Intrusion Safe Alarming" system is designed for alarming as soon as humidity or a drop of water is detected on a ribbon alike sensor.
The fail safe alarming system LISA includes, as a minimum, one ribbon alike sensor or one-point detector, plus one alarm relay ES5000.
The LISA system is dedicated for leakage detection on water distribution (pipes, sprinklers) and alarming in case of water, condensates or humidity in areas where water is prejudicial for equipments:
- Computers, electronic devices, machinery - High electric power station -
Located in computer rooms, medical equipments - HVAC moisture prevention - Museum - Stores, etc.
The ribbon alike sensor is designed with two metallic wires strapped together at one end with a resistance as a shunt. Both wires are insulated from each other by an absorbent fabric ribbon. The special material used for the ribbon, contains ionic ingredients, which allowed detection of water, even demineralised water.
The ribbon is applied all along any surface or following curves of pipes.
As soon as there is humidity somewhere on the ribbon, the system resistivity changes and switch on the alarm signal, even before a significant amount of water could be find out!
The relay ES5000 includes a self diagnostic of the detection loop (short circuit on the loop detection and ribbon sensor break off) in order to warranty a positive safe detection system.
