Smoke Detector Installation & Maintenance


A working smoke detector saves lives. Since July 2022, an approved smoke detector is legally required on every residential floor in the Netherlands.

Ninova Elektrotechniek ensures your home fully complies with the latest regulations. We install professional, interconnected 230V mains-powered detectors equipped with a reliable back-up battery.


  • Interconnected smoke detectors – If smoke is detected upstairs, all alarms in the house go off simultaneously so everyone is warned immediately.


  • NEN 2555 installation – We place the smoke detectors in the correct strategic locations (such as escape routes and hallways) according to legal regulations.



  • Maintenance & inspection – Replacing outdated detectors (which need to be replaced after 10 years) and checking the wiring.


When to check or replace your smoke detectors?


  • Detectors are older than 10 years – The sensor becomes unreliable after this period.


  • Regular short beeping sounds – The battery or the entire detector needs replacement.


  • During renovations or remodeling – The perfect time to switch to safe 230V mains power.



  • Not a detector on every floor – This is mandatory for your safety and home insurance.


Frequently Asked Questions


Why choose 230V mains-powered smoke detectors?


Mains-powered detectors are the most reliable and eliminate the hassle of empty batteries. They include a back-up battery in case of a power outage.


Do the smoke detectors need to be interconnected?


Yes, we highly recommend it. If a fire starts downstairs, the upstairs detector alarms instantly. This gives you crucial extra time to escape safely.
