Why do GEZE GC 304 R open the door for no apparent reason?

  Jeffrey PerryJul 25, 2025
  Your GEZE security sensor might be opening the door for no apparent reason due to several factors: * Rain: The sensor may be detecting the movement of raindrops. Installing a rain cap can resolve this. * Metallic environments: The sensor could be detecting objects outside of the intended detection area. Try changing the antenna angle. * Interlocking door systems: The sensor might be picking up movement from the opposite door. Reducing the area size can help.

  David WilliamsAug 17, 2025
  If the door controlled by your GEZE security sensors remains closed and the LED is off, it could be due to these reasons: * The power supply might be off. Check the cabling and voltage of the power supply. * The door controller parameter (F2) might be set to value 3 (closed). Set the door controller to automatic.
