Our QFire fireman's switch: Now even smarter!

Since last year, we have been working hard on our QFire firefighting switch - there's always room for improvement! These are the exciting new features (and we already have a lot more in the pipeline, but shhhh...):

Keep a cool head and maintain an overview at all times, no matter where you are: Our new online monitoring makes it possible. So you or the system operator always have safety in view!

Plug & Play

Wiring it yourself is boring, we know. Not so easy when we build our QFire customized to perfectly match YOUR system. But hey, we've thought of something 🙂 - and no, it couldn't be easier - thanks to our plug-and-play solution, the QFire fireman's switch is installed in a flash and ready for immediate use!

Success stories

Our QFire PV fire switch is already a real success. Here are two examples that we are particularly proud of:

Generator activation: Fire service switch for Kessler in Abtsgmünd

A 124,000 m² solar power plant on the production halls of the Kessler company, equipped with our QFire PV firefighting switch - great! In this case, the specification was that the housing of the activation boxes should be made of metal, which of course posed no problem for us. A total of 80 of our fireman's switches disconnect the DC generator from the inverter with a time delay when triggered in order to minimize voltage dips.

QFire PV fire department switches optimize safety for the photovoltaic system at Ladenburger

The construction of a large-scale PV power plant with a total output of 4.7 MWp on the hall roofs of the Ladenburger company in Bopfingen represents a significant step towards sustainable energy generation. Particular attention was paid to safety, especially the protection of firefighters. The cables are laid on traverses and routed through our fire department switch boxes, which enable both central disconnection - via the fire alarm control panel - and decentralized disconnection - at each relevant traverse. This allows the firefighters to carry out their extinguishing operation safely.
