Grevenbroich Firefighters Build a Smarter, Cheaper Smoke Alarm Network

Grevenbroich Fire Department has upgraded its fire safety measures with a new wireless smoke detection system. The project, completed entirely in-house, links 185 smoke alarms across eight fire stations and 39 emergency vehicles. Officials say the system will speed up emergency responses and reduce costs in the long term. The department installed a networked smoke alarm system that instantly sends alerts to the DIVERA app. This allows for faster reaction times in emergencies. The total material cost came to around €12,500—far less than the €225,000 quoted for similar external systems.

By developing the interface themselves, the team retained full administrative control. This ensures future upgrades, maintenance, and adjustments remain affordable. The move follows a growing trend of fires at fire stations caused by technical faults across Germany. All 185 alarms are interconnected, providing early fire detection in both buildings and vehicles. The system's efficiency and cost savings have been highlighted as key benefits of the project.

The new smoke detection network is now operational across Grevenbroich's fire stations and emergency fleet. It delivers real-time alerts while cutting expenses by over €200,000 compared to third-party solutions. The department plans to maintain and expand the system as needed in the coming years.
