Your Service

Maintenance of your fire safety systems

A fire safety system must remain operational at all times to ensure the protection of people and property and to maintain business continuity.

Through its nationwide network, local teams, and support services, DEF supports the operation, maintenance, and long-term sustainability of your installations throughout their entire lifecycle.

A poorly maintained installation poses a risk to your establishment

Even if it is perfectly designed, a fire safety system can become less effective over time:

clogged sensors
aging batteries
obsolete equipment
communication problems
components that are no longer available
outages affecting operations

A malfunction can compromise early fire detection, the safety of occupants, or the building’s regulatory compliance. Preventive and corrective maintenance help ensure system availability and minimise business disruptions.

Maintenance contract

Fire safety systems must remain available at all times, including outside of business hours. Maintaining fire safety systems is critical to ensuring their reliability, regulatory compliance, and long-term availability.
Maintenance contract
Preventive & predictive maintenance

Corrective maintenance is performed when a malfunction or failure affects the fire safety systems. It aims to quickly restore the proper functioning of the installations, minimise the impact on operations, and ensure the continued protection of people and property.

On-call service

Fire safety systems must remain available at all times, including outside of business hours. The 24/7 on-call service ensures service continuity, rapid incident response, and operational security at all times.

Call centre

The call centre serves as the centralised point of contact for managing requests related to fire safety systems: incident reporting, requests for intervention, tracking of actions, and coordination of teams.

Refurbishment of fire safety systems

Refurbishment extends the service life of fire safety systems while maintaining their reliability and compliance, without immediately undertaking a complete replacement project.

Anticipate changes rather than react to them

Modernising a fire alarm system involves more than just replacing equipment.  It aims to adapt the system to the site’s current and future constraints without disrupting ongoing operations.

The continuous availability of systems

Ensure the systems are always available to guarantee continuous protection of people and facilities under all circumstances

Traceability of actions and interventions

Ensure the traceability of actions and interventions to guarantee monitoring, compliance, and the continuous optimisation of systems

Compliance with current standards

Ensure compliance with current standards to meet regulatory requirements and ensure the safety of facilities and occupants

Failures in critical situations

Prevent failures in critical situations to ensure system reliability and guarantee an effective response in the event of an emergency

A comprehensive and structured maintenance program

Maintenance contract

Fire safety system maintenance contract A clear framework for ensuring preventive and regulatory maintenance of installations, with scheduled, documented maintenance tasks tailored to the site’s specific constraints.
Corrective maintenance

The ability to respond quickly in the event of a malfunction, in order to restore system operation and minimise the impact on safety and operations.
24/7 on-call service

An on-call system designed to respond to critical situations outside of standard business hours and ensure continuity of service.

Maintenance tailored to your operational constraints

DEF provides maintenance for fire safety systems at sites with stringent requirements: Public access buildings, industrial sites, commercial buildings, healthcare facilities, or multi-site portfolios.
Each site has its own specific requirements regarding access, operating hours, business continuity, and coordination.  DEF maintenance is designed to be carried out efficiently, without disrupting operations.

Support tailored for operators and safety managers

Fire safety system maintenance and support directly involve:

Operators and security managers: ensuring system availability and compliance
Technical and real estate management: overseeing installations that are sometimes complex or span multiple sites
QHSE Managers: ensuring clear and usable traceability

L’objectif The goal: to ensure safety without making daily life more difficult.

Maintenance that paves the way for system upgrades

Maintenance isn’t just about keeping things as they are.  It also helps identify the limitations, obsolescence, and opportunities for improvement in fire safety systems.

Building on this foundation, DEF then works with its customers to modernise their installations and enhance their teams’ skills, without disrupting operations.
