Attach your smoke detector without drilling, screwing or noise. No damage to the ceiling or cables. Very simple and quick installation using two self-adhesive magnetic plates. The smoke detector can be easily removed again (for tests, changing batteries, etc.). Not suitable for vinyl wallpaper, polystyrene, non-stick, siliconized or Teflon-coated surfaces. Only partially suitable for smoke detectors with a diameter of less than 8 cm. Not for use in commercial properties (impact-resistant fastening required).
