Triton ZACZEP ELEKTRA R4 with internal memory — smart door strike, symmetric, model 2026

Triton ZACZEP ELEKTRA R4 with internal memory — smart door strike, symmetric, model 2026 is a symmetric electric door strike designed for controlled remote release and reliable mechanical locking in access control systems. The device is intended for installations where a symmetric latch is required and includes an internal memory function to store the last release state. It is suitable for use with intercoms, access control panels and electronic locking setups in both residential and commercial environments.

Advantages

The symmetric design allows installation in frames with reversible latch orientation, reducing the need for separate left- and right-handed models. The integrated internal memory records recent release events to support synchronization with access control devices and intercom systems. The unit delivers consistent electric release performance and is compatible with common power and signal configurations used in door entry installations. Its construction provides a balance of mechanical robustness and compact dimensions for mounting in standard metal or wooden frames.

Suitable for

• Apartment and house entry doors controlled by intercom systems
• Commercial and office doors with electronic access control
• Retrofit projects where symmetric latch compatibility is needed
• Security setups requiring remote release and state memory

Key specifications

• Symmetric latch compatibility for reversible left/right installation
• Internal memory function to store the last release state
• Electric release mechanism suitable for remote operation
• Designed for flush or surface mounting in door frames made of wood or metal
• Construction balanced for mechanical durability and compact footprint

How to use

Mount the strike in the door frame oriented to match the latch tongue, using compatible fasteners for the frame material. Connect the device to the building’s access control or intercom wiring according to the installer’s wiring diagram and local electrical standards. Configure the control unit to provide the correct release signal and test the internal memory reporting by cycling the release command and verifying the stored state with the connected control equipment. Ensure power is disconnected during mechanical installation and wiring changes.

Usage recommendations

Install and configure the unit following local electrical regulations and access control system instructions. For reliable operation, use appropriate power supply and signal levels recommended for electric strikes, and perform periodic inspection of the mechanical components and wiring connections. In retrofit or irregular frames, verify fit and reinforcement needs before final installation.
