Electric strike, fail-safe (NO), XS12R, HARTTE, BIRA

The HARTTE XS12R is a compact fail-safe (normally open) electric strike designed for access control systems that require automatic unlocking when power is lost. Its slim 16.2 mm body and symmetric construction make it ideal for narrow aluminum and metal frames. The strike offers 3000 N break-in resistance, up to 200,000 operating cycles and a 3.5 mm radial latch adjustment, ensuring reliable performance in demanding applications.

Main features

Technical characteristics

The XS12R operates in fail-safe (NO) mode – the door is kept locked only when power is present, and automatically unlocks during a power failure. This behaviour is crucial for emergency exits and safety-critical installations. The robust mechanical design and strong housing provide up to 3000 N break-in resistance and long-term durability.

Installation and compatibility

Thanks to its symmetric body, the electric strike can be mounted on both DIN left and DIN right doors, in vertical or horizontal orientation. The narrow 16.2 mm width allows installation in slim aluminum and metal frames commonly used in commercial and office buildings.

FAQ (Frequently Asked Questions)

Is the HARTTE XS12R suitable for emergency exit doors?

Yes, the XS12R operates in fail-safe (normally open) mode. When the power supply is interrupted, the latch is released and the door can be opened, which makes it suitable for emergency exits and evacuation routes.

Can this electric strike be installed in narrow aluminum profiles?

Yes, the 16.2 mm slim body is designed for narrow aluminum and metal frames, commonly used in modern commercial and office buildings.

Is the HARTTE XS12R compatible with both DIN left and DIN right doors?

Yes, thanks to its symmetric construction, the strike can be installed on both DIN left and DIN right doors without additional mechanical modifications.

What level of mechanical break-in resistance does the strike provide?

The HARTTE XS12R offers up to 3000 N break-in resistance, providing a solid level of physical security for most access control applications.

Is latch adjustment available and why is it important?

Yes, the strike features a 3.5 mm radial latch adjustment. This allows the installer to fine-tune the position of the latch relative to the frame, ensuring smooth door closing and reliable locking and unlocking.
