for securityfor home automation systemfor building automation systems

Product overview

• Operating frequency: 433.92–868.35 MHz.
• Radio code: FDS (FAAC DIGITAL SIGNATURE).
• Available models: XT2 FDS (2-channel) and XT4 FDS (4-channel); BD bidirectional variants: XT2 FDS BD, XT4 FDS BD.
• FDS (FAAC DIGITAL SIGNATURE): FM-based radio protocol engineered for extended range and battery life. Radio transmissions are protected by AES-128 symmetric encryption (128-bit key).
• Remote authenticity is verified through a chain of FAAC-customized security certificates.

Advantages

• Maximum protection against cloning enabled by an advanced security scheme with Secure Vault™ (PSA™ Level 3) and TrustZone® hardware technologies.
• Dual-frequency operation: transmitters and receivers communicate at 868 MHz and 433 MHz in time-sharing mode, removing the need to preselect the working frequency.
• Easy registration: simplified registration and management via SELF LEARNING or direct registration on the receiver.
• SLH compatible: FDS transmitters can operate as slaves on existing SLH systems if required.
• PHYGITAL and remote management: FAAC PHYGITAL transmitters integrated with Simply Connect enable remote add/remove/enable/disable and time-band management without dedicated onsite tools.

Security & Integration
Advanced security architecture combining Secure Vault™ and TrustZone® technologies. Integration with Simply Connect adds an extra layer of protection against cloning by verifying the authenticity of each transmitter ID and enabling centralized remote management.
