Fire detection for construction sites

Ensuring fire safety during construction
During maintenance or renovation work, facilities are particularly vulnerable to fire hazards. Work in hot spots, modified technical areas, and temporarily disabled detection systems: all of these situations compromise site security.

It is against this backdrop that organisations such as the Compagnie de Chauffage de Grenoble and the Forum des Halles have chosen to implement a temporary fire detection system.

How can effective fire safety be maintained during construction work when the fire protection system is partially unavailable?

Certain industrial sites or facilities open to the public must regularly carry out maintenance or renovation work, particularly during the summer months.

These operations often involve work at hot spots (welding, grinding, cutting), which significantly increase the risk of a fire breaking out.

In addition, the work may require the temporary deactivation of certain existing fire detectors, which will temporarily reduce the site’s level of protection.

This situation corresponds to a state of compromised fire safety, in which the fire safety system is no longer fully functioning as intended.

How can a facility remain operational while ensuring fire safety without continuous monitoring?

This is particularly true of the Compagnie de Chauffage de Grenoble and the Forum des Halles, where certain operations take place even though the facilities are unoccupied at night or on weekends.
During these periods, there are not always staff members on site to provide continuous fire watch.

Operators must therefore find a solution that allows them to maintain reliable fire monitoring in compliance with insurers’ requirements, while continuing maintenance operations safely.

There are two key issues:

  • ensure the safety of people and infrastructure
  • ensure business continuity during the construction work

What is the best way to temporarily secure a construction site?

To address these challenges, the sites have chosen to deploy the FIRETEMP mobile fire detection solution offered by DEF (Détection Électronique Française).

This temporary detection system makes it possible to temporarily secure areas under construction, even when the permanent fire detection system is partially disabled. Easy to install and exceptionally durable, it can be quickly deployed in challenging environments such as dusty, technical, or constantly changing areas.

How does this solution work in real-world conditions?

The system provides continuous monitoring of sensitive areas and immediately sends alerts if an anomaly is detected. Notifications can be sent remotely, such as via text message or through an online monitoring platform, allowing technical teams to be notified in real time and to respond quickly if necessary.
This flexibility makes it possible to adapt fire protection to the various phases of construction while maintaining a high level of safety.

“FIRETEMP is a mobile, rugged, and easy-to-deploy system. It allows us to work in dusty environments during construction while ensuring safety. “We can temporarily cover the sensor heads during the work and then remove the covers to quickly get the system back up and running.”
Director of technical and safety operations – Forum des Halles (Unibail-Rodamco Group)

 Maintain fire safety without interrupting your business operations

With this solution, DEF helps facility operators manage fire risks during critical maintenance or construction phases.

Beyond the hardware, the approach is based on a turnkey solution that includes:

  • the provision and installation of the device,
  • commissioning and configuring equipment,
  • monitoring and alert transmission,
  • as well as the maintenance and removal of the equipment once the work is complete.

This offering enables operators to temporarily secure their facilities without disrupting their operations, while ensuring service continuity and the protection of people, equipment, and infrastructure.
