## Summary description

The HARTTE S12RM Series S electric strike is a high-quality fail-safe (normally open) locking device designed for 12V DC systems. It features an integrated monitoring sensor to track the status of the door. Ideal for access control systems in commercial and residential buildings, this strike ensures reliable operation and enhanced security for various door types.

## Long description

The HARTTE S12RM Series S electric strike is a professional-grade locking solution engineered for 12V DC access control systems. This fail-safe, or normally open, device is designed to remain unlocked when powered, making it an essential component for fire safety and emergency exit routes where doors must automatically release upon power loss. The integrated monitoring sensor provides real-time feedback on the door's status, allowing security systems to track whether the door is properly closed or open.
Advantages
This electric strike offers exceptional reliability and seamless integration into modern security infrastructures. Its fail-safe operation ensures compliance with safety regulations in public and commercial buildings. The built-in monitoring contact adds an extra layer of security by communicating the door state to the central control unit. Constructed with high-quality materials, the device is designed for long-term durability and consistent performance under frequent use, ensuring that access control remains efficient and secure.
Suitable for
Fire exit doors and emergency escape routes
Commercial office buildings with access control systems
Residential apartment complexes requiring remote door management
Public buildings where fail-safe operation is mandatory
This device may not be suitable for high-security applications where a fail-secure (normally closed) mechanism is required to keep doors locked during a power outage. It is also not intended for outdoor environments without appropriate weather protection, as moisture or extreme temperatures may affect its internal electronic components.
Key specifications
Operating voltage: 12V DC
Operation mode: Fail-safe (normally open)
Integrated monitoring: Yes
Series: S
To install the HARTTE S12RM Series S, ensure the door frame is prepared for the strike dimensions and that the wiring is correctly connected to a 12V DC power supply and the monitoring input of your access control panel. The strike should be mounted securely within the door frame, ensuring proper alignment with the latch bolt to prevent mechanical binding. Once installed, test the electrical operation and the monitoring signal to confirm that the system correctly identifies the door status.
What to consider before purchase
Verify that your access control system supports 12V DC power
Confirm that a fail-safe (normally open) mechanism meets your local fire safety regulations
Check the physical dimensions of your existing door frame to ensure compatibility
Ensure your control panel has an available input for the monitoring sensor
For optimal performance and longevity, ensure the strike is kept clean and free of debris. Regularly test the fail-safe functionality and the monitoring sensor to confirm that the system remains fully operational and compliant with safety standards.
