HID 920PHRNEK0004V RP40-H Pivclass SE HF SIO SEOS Reader

HID 920PHRNEK0004V RP40-H PIVCLASS Smart Card Reader

Overview

The HID 920PHRNEK0004V is an RP40-H PIVCLASS-compliant smart card reader engineered for secure access control systems where credential verification and identity management are mission-critical. This reader supports both low-frequency (LF) standard and high-frequency (HF) standard protocols alongside advanced encryption modes including FIPS and Crypto Authentication Key (CAK) support, making it suitable for government, enterprise, and high-security integration deployments.

Key Features

• PIVCLASS Compliance: SE E rating ensures alignment with federal and enterprise identity credential standards
• Dual-Frequency Capability: LF standard and HF standard/SIO/SEOS/FIPS/CAK support enables multi-protocol credential reading
• 485FDX Communication: Full-duplex RS-485 serial interface provides robust, noise-immune data transmission over extended cable runs in electrically noisy environments
• FIPS 40-Bit Encryption: Hardware-enforced encryption protects credential data in transit and at rest
• Wiegand Protocol Support: Native Wiegand output enables direct integration with legacy and modern access control panels
• BCD Output Format: Binary-coded decimal output option supports controllers requiring alternative data encoding
• Open Collector Output: Discrete output relay logic for custom integration workflows and third-party panel compatibility
• Optional Tamper Detection: Built-in tamper switch protection against physical device compromise
• Visual Indicators: Red LED status indication with green flash confirmation feedback for operator feedback
• Audible Alert: Buzzer enabled for access event confirmation
• Compact Form Factor: Black standard enclosure (STD-1) sized for wall mount or panel integration
• PIG Configuration: Integrated pin-and-gate credential processing optimizes reader performance in multi-credential scenarios

Integration and Compatibility

The 920PHRNEK0004V integrates with security systems requiring PIVCLASS-compliant card readers. The 485FDX full-duplex RS-485 interface supports runs up to 4,000 feet with proper termination, making this reader suitable for large facility deployments, distributed access control architectures, and retrofit installations where cable infrastructure already exists. Native Wiegand output (WIEG ON) and optional BCD encoding ensure backward compatibility with installed access control panels while supporting modern IP-based security platforms. IPM (intelligent power management) is disabled in this configuration, allowing direct power control by the host system.

The reader operates in standard UART mode with UART functionality disabled in firmware, optimizing performance for RS-485 command/response cycles. UART OFF configuration prevents data collision and ensures deterministic communication timing in multi-reader deployments. The PIG (pin-and-gate) mode handles sequential credential validation, reducing false accepts in high-security applications.

Operational Specifications

This model provides optional tamper detection (OPT TAMP enabled) to alert security teams of physical tampering attempts. The open collector output configuration permits discrete relay control logic, enabling door strike activation, alarm triggers, or multi-factor authentication workflows. Red LED indicator with green flash acknowledgment provides clear real-time status feedback. The buzzer is activated (BZR ON) for audible event notification. All encryption operates at FIPS 40-bit standard, meeting compliance requirements for federal and enterprise access control audit trails.
