An electric door opener makes it possible to unlock a door via an electrical impulse. This technology has long been a standard feature in apartment buildings, allowing visitors to be conveniently admitted via the intercom system without the resident having to go to the front door. However, electric door openers are also increasingly being used in single-family homes, office buildings, and commercial properties.

How does an electric door opener work?

The electric door opener is mounted directly in the door frame and does not replace the lock itself; instead, it acts on the latch. When an electrical impulse is triggered, the opener releases the latch, allowing the door to be opened. The door does not need to be unlocked for this to happen.

Most electric door openers operate on a voltage of 8 to 12 volts. They can be powered by either alternating current (AC) or direct current (DC). While alternating current produces a clearly audible buzzing sound, direct current usually results in only a brief click. The familiar buzzing sound heard at the entrances of many apartment buildings is caused by operation with alternating current.

Fail-secure electric door opener

The most commonly used type is the so-called fail-secure electric door opener. In this system, the door latch is released only as long as power is applied. When someone presses the door release button on the intercom, the door can be opened.

Many models also feature practical convenience functions:

Permanent release via mechanical switch
Daytime release for frequent entry and exit
Unlocked until the next opening operation

Such functions are particularly practical for delivery traffic, in office buildings, or for single-family homes that receive frequent visitors.

Fail-safe electric door strike

A special type of design is the fail-safe electric door opener. With this system, the door remains locked only as long as power is supplied. If the power supply fails, the door is automatically released.

This technology is primarily used for escape and rescue routes. It ensures that the building can be safely exited at any time in an emergency or during a power outage.

Advantages of an electric door opener

Electric door openers elegantly combine convenience and security. Visitors can be conveniently admitted from the apartment or office without the resident having to go to the door. When combined with an intercom or video door entry system, it is also possible to precisely control who is granted access.

Key advantages include:

Convenient door opening at the touch of a button
Enhanced security through controlled access
Ideal for apartment buildings, offices, and commercial properties.
Integration into intercom systems, video systems, or access control systems
Less wear and tear from frequent locking and unlocking

Electric door opener as a component of modern access control

Modern electric door openers can be combined with numerous systems. In addition to traditional doorbell systems, the following solutions are possible, for example:

Transponder and chip systems
PIN code keypads
Fingerprint-Scanner
Smartphone control
Electronic locking systems

This makes it possible to completely dispense with traditional keys in many areas. It reduces administrative effort and minimizes the risks associated with lost keys.

For which doors are electric door openers suitable?

Electric door strikes can be retrofitted to many different types of doors, including:

Entrance doors for single-family and multi-family houses
Garden gates and courtyard gates
Office and practice entrances
Commercial Access
Side entrances and service doors

Which version is suitable in a specific case depends on the structural conditions as well as the desired safety and comfort functions.

Conclusion

Electric door openers are among the most important components of modern access control systems today. They enable convenient and secure remote unlocking of doors and can be integrated with a wide range of security and smart home systems. Whether for apartment buildings, single-family homes, or commercial properties, the right solution enhances everyday convenience while ensuring a high level of security.
