AREI Connection: Smoke Detectors and the Electrical Inspection
An important note: smoke detectors are not directly regulated by the AREI. The AREI primarily regulates the electrical installation — cables, fuses, earthing, etc. Art. 9.1.2 Nr. 2 requires that the electrical installation file includes a site plan; its prescribed content is exhaustively defined (sockets, switches, lighting points, and fixed appliances or machines) and does not include smoke detectors.
Since smoke detectors are not part of the AREI-regulated electrical installation, they are not subject to the electrical inspection (keuring); a missing smoke detector does not result in an AREI deficiency. Some installers or inspectors nevertheless show smoke detectors on the situation plan for information, to document the position of all relevant devices in the dwelling.
Maintenance and Replacement
- Monthly: Press the test button to check functionality
- Annually: Thorough testing and dust removal
- Every 10 years: Replace the smoke detector completely (sensors lose sensitivity)
- Only use detectors with CE marking and compliant with NBN EN 14604
