Electric strike VIDOS Bira 12VDC symmetrical R5 for door locking systems, model 8909

The VIDOS Bira 12VDC symmetrical R5 electric strike (model 8909) is a 12 V DC powered door strike designed for integration with access control and door locking systems. Its symmetrical R5 construction enables reversible installation for either left- or right-hand doors, making it adaptable to a variety of door frames and entry configurations. The unit is intended for use with intercoms, electronic locks and other door entry equipment in residential and commercial environments.

Advantages

The symmetric R5 mechanism provides straightforward reversible mounting without the need for separate left- and right-handed models, reducing inventory complexity. Operation on 12 V DC ensures compatibility with common access control power supplies and intercom systems. The strike is built for reliable mechanical release cycles and is suitable for frequent use in both domestic and light commercial applications. Its compact design and standardized fixing points simplify retrofit and new installations in typical door frames.

Suitable for

• Residential apartment intercom and entry systems
• Office and small commercial door access control
• Retrofitting existing door frames to add electronic access
• Integration with video-doorphone and remote release systems

Key specifications

• Operating voltage: 12 V DC
• Symmetrical reversible latch design for left or right door mounting
• Designed for electric strike function (mechanical release on control signal)
• Compact form factor compatible with standard door frame cutouts
• Intended for use with intercoms, electronic locks and access control systems

How to use

Install the electric strike into the door frame cutout using the appropriate screws and alignment for the latch. Connect the 12 V DC power supply and control wiring according to the access control or intercom system instructions, observing correct polarity. After installation, test the strike operation by triggering the release from the intercom or control unit and verify smooth mechanical engagement with the door latch in both left- and right-hand orientations if applicable. Ensure wiring is secured and insulated to prevent short circuits and that the strike plate aligns cleanly with the door latch for consistent operation.

Usage recommendations

Use a stable 12 V DC power source sized for the combined load of the strike and any other connected devices. Periodically inspect mechanical alignment, mounting screws and wiring for wear or loosening. For high-frequency commercial entrances, consider pairing the strike with a compatible power supply and monitoring device to ensure long-term reliability.
