Door electric strike ORNO OR-EZ-4029, low-current 280 mA for 12 V DC, with door-open fault signaling

Electric strike ORNO OR-EZ-4029 is a low-current 12 V DC door locking device designed for access control systems. It provides a mechanical latching release that allows remote unlocking while keeping the door frame and lock compatible with standard latch systems. The unit draws 280 mA under operating conditions and includes an electrical contact for signaling when the door is not fully closed, enabling straightforward integration with alarms, intercoms, or control panels. The compact construction permits installation in metal and wooden doors for both residential and commercial applications.

Advantages

The ORNO OR-EZ-4029 offers low power consumption suitable for systems with limited power budgets and for battery-backed installations. Its door-open fault signaling improves security and convenience by reporting incomplete latching, and the mechanical release mechanism ensures compatibility with common latch locks. The design supports straightforward electrical connection and integration into existing access control or alarm setups without complex modifications.

Suitable for

• Residential entry doors with electronic access control
• Commercial interior doors in offices and retail environments
• Integration with alarm systems and intercoms to signal door-open faults
• Retrofit installations in metal or wooden door frames

Key specifications

• Operating voltage: 12 V DC
• Typical current consumption: 280 mA
• Function: mechanical latching release with electrical door-open signaling
• Suitable door types: metal and wooden doors
• Compatibility: designed for use with standard latch locks and access control systems

How to use

Install the electric strike into the door frame according to the frame and lock dimensions, ensuring proper alignment with the latch. Connect the 12 V DC supply and the signaling contact to the access control or alarm panel following the electrical diagram provided by the system integrator. After electrical and mechanical installation, test the latch release and the door-open fault signal by operating the locking device from the control system and by checking the signal when the door is left ajar.

Usage recommendations

For reliable operation, use a stable 12 V DC power source sized to handle the 280 mA load plus any additional devices on the same supply. Verify alignment between the latch and strike during installation to prevent premature wear. If integrating with an alarm or control panel, configure the input for the door-open contact according to the panel’s specification and test the signaling function during commissioning.
