A fire detection system aims to detect and report as early as possible the beginnings of a disaster, in order to reduce the time required to implement fire-fighting measures and to limit its impact. The automatic fire detectors (DAI), are based on various technologies that can be used to search for phenomena relating to an […]

FIRE Temp, a temporary fire detection solution, was designed to secure the sites during the construction phases: periods involving major risks of blaze outbreaks, often with significant financial consequences due to equipment damage. The FIRE Temp system consists of a frame carrying an addressable SSI panel and a box for sending alarms and fault reporting […]

In high-ceiling rooms, the difference in temperature between the cold air at the bottom of the building, the hot fumes that rise and cool as they ascend, and the possible hot air cushion under the roof created by the sun lead to a phenomenon of stratification of fumes, which can render a standard electronic detection […]

The fire safety control panels (CMSI), are PLCs whose purpose is to protect people and property by facilitating the intervention of the emergency services. The CMSI corresponds to a set of devices securing a building: the operation of the evacuation diffusers (evacuation function), the closing of doors and fire valves (compartmentalisation function), the opening of […]

DEF has entirely designed and developed the VisioDEF 3D: next-generation software package. This in-house development makes it suitable to the specificities encountered, in order to supervise all building safety equipment. Open to a large number of professions, the VisioDEF3D supervision system covers in particular the fields of fire, extinguishing, emergency exits, security PA system, camera […]

Normally referred to as the Central Element of the Vocal Fire Alarm System (ECSAV), the security PA system (SSS) can be associated with a fire safety system, especially to meet the requirements and evacuation obligations of certain sites. The SSS offers two main functions: the first is to authorise, following a command from the Alarm […]

Automatic gas extinguishing systems act at the very core of the risk to protect people and property while preserving the environment. Based on inert gases, the technologies developed by DEF guarantee total extinguishing, while respecting people and the environment. DEFinert Matrix is DEF’s natural and eco-friendly automatic extinguishing solution. It is based on IG55: an […]

Water is a natural extinguishing agent. Defragmented into micro droplets (less than 1 mm in size) and sprayed at low, medium or high pressure, depending on the risk to be protected, the water spray cools the combustion and enables to control the blaze. It is not very restrictive, easy to implement, safe for humans and […]

Mechanical smoke extraction is one of the essential means used to secure buildings. It enables the evacuation of fumes and thus contributes to the safety of people, by facilitating the evacuation of occupants of an establishment. The mechanical extraction of fumes also contributes to the safeguarding of structures. Mechanical smoke extraction is automatically activated in […]

Video surveillance is known as video protection when it is used on public land. It is a system of cameras and image transmission, placed in a specific space, to monitor it remotely. Images obtained with this system can be processed automatically and/or viewed and then archived or destroyed. From simple individual housing to a sprawling […]

An intrusion detection system is a mechanism for detecting abnormal or suspicious activity on an analysed target. It thus enables one to know about successful attempts as well as failed intrusions. The DEF Network offers various anti-intrusion solutions, depending on the sites to be protected: infra-red barriers and detectors, volumetric radars, opening or impact contacts […]

Access control refers to the various technical solutions that make it possible to secure and manage physical access to a building or site. The DEF network controls the entire access control system and assists you in implementing complete solutions: operating software, site access equipment (vehicle weighing, license plate reading, boom barrier, turnstile, badge reader, etc.).
