Electric Strike Commax EL1-003 by BIRATRONIK — standard electromechanical strike with AC switch

The Commax EL1-003 by BIRATRONIK is a standard electromechanical electric strike with an AC switch, designed for integration with intercoms, access panels and security systems. It provides electronically controlled latch release for doors and frames where secure, remote unlocking is required. The unit is suitable for both retrofit projects and new installations where a compact, mechanically reliable strike is needed.

Advantages

The electric strike features an AC-switch mechanism that enables compatibility with alternating current access control systems and intercoms. Its electromechanical design offers consistent latch operation and reliable remote unlocking. The construction is compact and intended for straightforward installation in common door frames, helping to minimize modification work during upgrades or replacements.

Suitable for

• Residential and small commercial entry doors paired with intercom systems
• Retrofit projects where an existing mechanical strike is replaced by an electromechanical unit
• Access control panels and security systems requiring remote release of a latch
• Doors with standard mortise or surface-mounted strike preparations compatible with common electric strikes

When it may not be suitable

This model is a standard electromechanical strike intended for typical door and frame configurations; it may not be suitable for high-security environments that require fail-safe biometric or electromagnetic locking solutions. It is also not intended for heavy industrial doors or specialty frames that need bespoke strikes with enhanced mechanical reinforcement.

Key specifications

• Operation type: electromechanical electric strike with AC switch
• Intended mounting: standard door frame installation for latch release
• Compatibility: designed to work with intercoms, access panels and common security systems using AC activation
• Use case: suitable for retrofit and new installations requiring electronic latch control

How to use

Install the electric strike into the door frame at the latch location according to the frame and door type, ensuring correct alignment with the door latch. Connect the AC supply and control wiring from the intercom or access panel to the strike’s switch terminals following the equipment manuals and local electrical codes. Test operation by activating the intercom or access control to confirm the latch releases and secures reliably. Adjust striker plate alignment if necessary to avoid binding.

What to consider before purchase

• Confirm door frame and latch dimensions match standard strike mounting requirements
• Verify the intercom or access panel provides compatible AC control output for the strike
• Check whether a fail-safe (power-to-lock) or fail-secure (power-to-unlock) behaviour is required by the installation and select accordingly
• Ensure electrical supply and wiring comply with local codes and the control system specifications

Usage recommendations

Use the Commax EL1-003 strike in installations where standard electromechanical operation and AC control compatibility are required. Perform a mechanical alignment check after installation and schedule periodic functional tests to maintain reliable locking and release performance.
