Étude de cas du projet TTK : TTK dans un musée Parisien


View the case study in PDF format


Project Background

An invisible place for museum visitors, the stock rooms are an essential part of a museum. Much more than a simple storage area, it is also a consultation, restoration, photography, and quarantine area sometimes requiring acclimatization. According to the French network of museum professionals, 80% to 90% of French museum collections are kept “in stock”. To insure these collections are safe from any kind of damage, it is important to adopt adequate safety measures for the entire areas. Water leak monitoring and detection is one of them.

Cooling units, water pipes networks, sprinkler systems, welfare areas are amongst numerous zones to be monitored besides the stock rooms within a museum building.


Project Requirement

  • In this project, zones to be monitored are spread on eight floors, requiring a large number of sensing cables. The client required a powerful and reliable water leak detection system capable of monitoring these large areas and detecting multiple simultaneous water leaks with precise location in case of leakage.
  • Low smoke zero halogen featured material were required to fit the fire safety


Areas to be Monitored 

  • Stock rooms and art galleries
  • Technical areas (Low voltage general boards; boiler rooms)
  • In-row cooling units
  • Chilled water piping networks
  • Sprinkler systems
  • Welfare areas


TTK’s Solution

Monitoring panels

Considering the extensive surface of the monitoring areas, TTK France recommended a combined digital leak detection monitoring solution, consisting of one monitoring control panel FG-NET and one satellite device FG-BBOX.

Monitored by the FG-NET via a standard Ethernet, the FG-BBOX has the same advanced functionalities as FG-NET and can manage two additional circuits of sensing cables. All commands and controls are centralised within the FG-NET as the FGBBOX does not have a display screen. In the event of a leak on a sensing cable connected on FG-BBOX, the alarm is directly shown on the FG Net.  Precise information, such as leak time and pinpoint location is displayed on an interactive map on the centralised monitoring panel.

On this specific project, almost 1 km length of sensing cables in total were installed and connected to the 3 circuits on the FG-NET panel and a fourth on the FG-BBOX panel. Utilizing the FG-BBOX in this installation is ideal as it allows an easy extension of the existing leak detection system (expected in the near future) .

Sensing cables:

Water sensing cables are installed in the perimeter of each stock room and technical room allowing an early detection of water coming from outside of the rooms.

Each sensing cable used in this museum is made with Low Smoke Zero Halogen material (reference FG-EC, FG-ECS), and emits limited smoke and no halogen when exposed to high sources of heat.

Over fifty national and regional museums throughout France are equipped with TTK leak detection systems. TTK’s intelligent sensing cables are also installed within the Le Louvre museum - Abu Dhabi, which Grand Opening took place in 2017.
