In the world of security systems, there is no room for compromise—especially when the safety of people, data, and infrastructure is at stake. The GRADE classification system allows for precise determination of the level of protection required for a given facility. The highest level—GRADE 4—is intended for the most demanding and strategically important environments, such as military facilities, government administration, research laboratories, or critical infrastructure.
At Roger, we not only understand these needs—we deliver solutions that meet them effectively.
RACS 5 with a Compliance Certificate
We are proud to announce that the RACS 5 access control system has received a certificate of compliance confirming that it meets the requirements of Security GRADE 4 in accordance with the EN 60839-11-1:2013 standard.
The certificate was issued under the CS TT 1a/2020 certification scheme, based on the 1a model described in EN ISO/IEC 17067:2013. Compliance was confirmed through independent testing conducted by an accredited certification body—the Czech Accreditation Institute. The certification confirms compliance with:
- EN 60839-11-1:2013,
- GRADE 4,
- Environmental classes I, II, and IV.
This means that RACS 5 can be confidently used in the most demanding projects, with full assurance of its effectiveness and compliance with European standards.
GRADE 4 – Requirements and Security Standards
The EN 60839-11-1:2013 standard classifies access control systems into four security grades (GRADE 1–4), with GRADE 4 representing the highest threat level. This requires the system to provide:
- Full control of every component—from identifiers to software,
- Continuous monitoring and tamper detection,
- Encrypted bidirectional communication,
- Environmental and mechanical resistance,
- Advanced access logic (e.g., anti-passback, dual credential),
- Low false acceptance rate for biometric readers.
What Does RACS 5 GRADE 4 Compliance Mean in Practice?
Compliance of RACS 5 with GRADE 4 is not just about meeting formal requirements—it’s about real readiness to defend against the most advanced physical and digital threats. In practice, this means the system:
1. Protects Data and Communication.
- Encryption and authentication of communication between readers and controllers (RS485, OSDP),
- Low-level encryption configuration for devices (MCT/MCX),
- Custom encryption key definition,
- Encrypted communication between controllers and server (AES128 CBC),
- TLS 1.2 support for VISO software connections to servers.
2. Ensures Secure User Identification.
- Support for MIFARE® Plus/DESFire cards with (PCN),
- Two-factor authentication (e.g., card + PIN),
- Blocking of identification points and/or credentials after failed login attempts,
- EM 125 kHz cards are not permitted in GRADE 4 systems due to insufficient security,
- PIN-only identification is not allowed—multi-factor authentication is required, and PIN length must correspond to the number of users.
3. Responds to Tampering and Abuse.
- Tamper detection (Tamper sensors),
- Support for forced entry and door held open alarms,
- Pre-alarm generation (visual or audible),
- Duress entry signaling (duress PIN),
- Event logging and acknowledgment by operators in the VISO SMS module,
- Event visualization on facility maps and support for security scenarios.
4. Ensures Operational Continuity.
- Monitoring of primary and backup power supply (minimum 4 hours of operation after power loss),
- Logging and reporting of power events,
- Support for MC16-PAC-x-KIT sets with 7Ah batteries,
- Activation of output lines in case of failure.
5. Enables Full Control and Supervision.
- Operator activity logging,
- Enforced strong passwords (min. 8 alphanumeric characters),
- Automatic logout after inactivity,
- Remote management of access points and door modes,
- Remote authorization and security scenarios,
- Time synchronization with NTP server.
Summary
The RACS 5 access control system meets all key requirements of the EN 60839-11-1:2013 standard for GRADE 4, as confirmed by an independent certificate of compliance. This means it can be safely deployed in high-risk facilities, ensuring not only physical protection but also full digital security.
For our clients, this is a confirmation that they are implementing a solution compliant with European security standards. Transparency in the certification process and compliance with standards are the foundation of trust on which we build our relationships with partners and end users.
