Electric strike Siemens ES1-001 BIRA symmetric 12V AC/DC basic

Siemens ES1-001 BIRA symmetric 12V AC/DC basic is an electric strike designed for basic access control installations. The unit accepts 12 V AC or DC power and provides a fail-safe mechanical release that unlocks the door latch when energized. Intended for framed doors and standard locks, this electric strike supports remote release of entrance doors in residential and light‑commercial environments.

Advantages

The symmetric design allows reversible installation for left- or right-hand doors without modifying the body. Operation on both AC and DC 12 V supply offers flexibility in integration with existing door entry systems. The built-in fail-safe release ensures that the latch can be released electrically while maintaining mechanical reliability and straightforward maintenance requirements. The compact housing suits installation in narrow door frames.

Suitable for

• Remote release of residential entrance doors
• Light-commercial access control points such as small offices or retail premises
• Framed doors with standard latch locks
• Systems requiring reversible strike orientation for left/right doors

How to use

Install the electric strike into the door frame following the frame and lock manufacturer’s instructions and local electrical codes. Connect the power supply to the unit using a compatible 12 V AC or DC source, observing correct polarity when using DC. Test the fail-safe release by energizing the strike and verifying that the latch retracts and the door opens. Ensure the strike is aligned with the door latch for smooth operation and adjust mounting position if necessary.

Usage recommendations

For reliable performance, use a stable 12 V power source sized to handle the strike’s inrush and operating current. Periodically check mechanical alignment and tighten mounting hardware. Avoid exposure to direct outdoor weather unless the door frame provides adequate protection. If integration with an access control panel or intercom is required, verify compatibility with 12 V AC/DC output or provide a suitable power conversion module.
