Transport

The DEF Company has outfitted many tunnels for which it has developed and integrated various solutions adapted to the specific needs and constraints of each project. These solutions have been installed in a wide variety of tunnels: rail tunnels, metro tunnels, road tunnels and also navigable waterway tunnels.

Drawing on these numerous and varied project experiences, the DEF Company accompanies its clients in defining and implementing the best solutions.

FIRE EYE is a solution for smoke and flame detection by image analysis.
It consists of video cameras loaded with a powerful image analysis algorithm and Visiodef 3D supervision software, enabling easy operation.

The use of this solution is recommended only in addition to conventional fire detection, in particular on sites with complex environments where the so-called “traditional” detection is not optimal in relation to the risk to protect, such as for very high-ceiling rooms where the stratification of fumes occurs well before the ceiling (aircraft hangar, etc.), or premises with very strong ventilation (tunnels, etc.).

PHENIX/S2H is a suction smoke detection system particularly suitable for monitoring equipment or critical volumes, such as bays or computer rooms.

Its high sensitivity enables early fire detection and offers the operator the possibility of intervening at the earliest.

The flexibility of the tubular network associated with the S2H detector integrated into it enables closer monitoring of the risk and precise localization of the source of a fire.

VISIODEF 3D is a supervisor fully compatible with DEF equipment. This software designed and developed by DEF offers real-time automatic synchronisation with the central equipment of the Fire Safety System. Any points added to the control panel loops are automatically created on the supervisor. The consistency of the site data is, therefore, permanently guaranteed between the panels and the supervisor, without any technical intervention from the manufacturer. VISIODEF 3D integrates, among others, an OPC solution, a wide range of graphic customisation and a very intuitive 3D graphical interface for a simplified and efficient localisation. In addition, VISIODEF 3D enables to combine the supervisor with other tasks such as the management of emergency exits, the SSS and doubt removal by camera.
