Data centre

Protecting data and ensuring business continuity

In a data centre, even the smallest incident can result in significant financial losses and disrupt the continuity of digital services. Infrastructure must remain operational at all times and protect critical equipment that operates 24 hours a day.

DEF conçoit, installe et maintient des systèmes de sécurité incendie spécialement adaptés aux environnements informatiques. Ces solutions permettent de détecter rapidement tout départ de feu, d’intervenir sans endommager les équipements IT et de garantir la disponibilité continue des infrastructures.

High standards for critical digital infrastructure

Data centres are not subject to a single regulatory framework. Their security is based on a set of regulations, standards, and technical guidelines designed to ensure the protection of infrastructure and the continuity of service.

The main fire hazards in Data Centres

An uncontrolled fire can result in: destruction of equipment, data loss, disruption of essential services, and enormous financial costs.

Fire caused by an electrical fault

Computer equipment, server racks, UPS units, batteries, or wiring can cause a fire to start.

Smoke spread

Even without a flame, smoke can quickly damage electronic components and cause systems to shut down.

Overheating and short circuits

The high energy density of computer equipment can cause overheating, which may lead to a fire.

Human error

A handling error or a delay in detecting an incident can quickly make the situation worse.

Service interruption

Any incident can affect operators’ availability commitments and result in significant penalties.

A few figures

When it comes to fire risks in public facilities, DEF supports you every step of the way: from auditing the installations to bringing them into compliance, all the way through to their ongoing maintenance. Our goal: to secure your buildings, protect their occupants, and ensure the continuity of your operations.

Applied solutions

Data centres have stringent fire safety requirements: rapid detection, equipment protection, and business continuity. DEF implements solutions tailored to IT environments and critical infrastructure.

Very early fire detection

Air-sampling detection systems and multi-criteria sensors can detect smoke particles even before a flame appears. This early detection system is particularly well-suited for server rooms and high-energy-density environments.

Automatic fire suppression without damaging the equipment

Inert gas fire suppression systems (nitrogen, argon, IG-55) can control a fire in its early stages without damaging electronic equipment or leaving any residue. They are particularly well-suited for server rooms, UPS rooms, and electrical cabinets.

Protection of technical areas using water mist

In areas where containment is more difficult, such as battery rooms or mechanical rooms, water mist is an effective solution for limiting the spread of fire while reducing water consumption.

Monitoring and control of fire protection systems

Monitoring platforms such as Fire360 bring together all the information from the fire safety system and the building services.
They provide a comprehensive, real-time view of facilities, facilitate alarm management, and improve coordination among on-site and remote operations teams.

En complément, Mon SSI Facile puts that information to work straight from a smartphone. The app notifies fire safety events in real time (fire alarm, fault, disablement) and guides the user through what to do, presenting the information clearly, by location and in order of priority.

This combined approach enhances the teams’ responsiveness, ensures sound decision-making, and simplifies the day-to-day operation of the fire protection system, even for non-expert users.
