What is the difference between AT and ADT?

According to the catalog, ADT models are similar to automatic AT models and include an unlocking lever. The AT range unlocks with a brief electrical pulse, without needing to hold down the button.

Does ADT mean high voltage?

No. The catalog describes this range as automatic with unlocking. The power supply voltage cannot be inferred from the acronym; the page consulted does not specify this for this reference.

Does the long format mean greater latch travel?

This should not be inferred from the name. The catalog entry identifies the long format, but does not specify greater travel or a compatible door thickness.

Checks before installation

The installer should check the power supply, control system, dimensions, mounting points, and operation against the existing installation. The intercom brand alone does not guarantee electrical or mechanical compatibility. Electrical checks and installation must be carried out by a qualified professional.
