Documented features

• NT normal operation.
• Standard format.
• Adjustable latch.

How does unlocking work?

Unlocking is maintained while the electric strike receives power. The control must keep the power on during opening, either by holding the button down or using a timed relay suitable for the installation.

How does it differ from an automatic AT model?

With NT normal operation, power is maintained during unlocking. The catalog describes the automatic AT range as unlocking with a brief electrical pulse, without holding the button down. They should not be considered direct replacements without checking the installation.

Does NT indicate the supply voltage?

In the catalog, NT identifies normal operation. The listing consulted does not specify the voltage or type of current for this reference; these should not be inferred from the initials.

Checks before installation

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