HID 922NTNNEK00291 iCLASS SE RM40 Reader Module
Overview
The HID 922NTNNEK00291 is a versatile reader module built on the RM40 platform, engineered for access control integrators requiring multi-credential support in a compact form factor. This reader combines HID's iCLASS SE technology with legacy credential compatibility, making it ideal for mixed-credential environments and retrofit installations. The module supports simultaneous operation across multiple card types and communication protocols, reducing the need for separate hardware across diverse access control deployments.
Key Features
- Dual-Frequency Operation: Standard HF (13.56 MHz) and low-frequency operation with LF OFF configuration, allowing selective activation based on credential requirements
- iCLASS SE Card Support: Native compatibility with HID's advanced iCLASS SE encrypted credential platform for enhanced security posture
- Multi-Protocol Output: Wiegand, magnetic stripe (MAG), and Proximity (PIG) output formats enable seamless integration with existing access control systems
- Extended Card Capacity: Supports Empire card format up to 34-bit encoding, accommodating high-capacity credential schemes required in large enterprise deployments
- Open Collector Configuration: 32-bit MSB (most significant bit) card serial number output via open collector interface for direct controller integration
- Visual and Audible Feedback: Red LED indicator with green flash feedback and buzzer activation (enabled) provides clear status confirmation during card presentation
- Tamper Protection: Optional tamper detection (OPT TAMP) adds environmental security monitoring for physical access control installations
- Standard Housing: Black finish (BLK) with STD-1 mounting specification for compatibility with standard mounting infrastructures
- IP Module Format: IPM OFF configuration supports direct integration into IP-enabled access control ecosystems without requiring separate gateway devices
- SIO/SEOS Modes: Supports both standard I/O and secure encrypted communications modes for credential transmission security
Integration and Compatibility
The HID 922NTNNEK00291 reader module integrates with both legacy and modern access control architectures. Wiegand output ensures compatibility with traditional access control panels, while simultaneous support for iCLASS SE credentials enables deployment of encrypted credential schemes without hardware replacement. The open collector interface provides flexible integration with custom control logic or direct wiring to access control controllers. Magnetic stripe support (MAG) allows organizations to continue supporting existing mag-stripe credential libraries during technology transitions. The module's multi-output architecture—combining Wiegand, magnetic, and Proximity formats—eliminates the need for credential-specific readers in heterogeneous environments.
Physical and Operational Specifications
The reader module operates with standard 12V power infrastructure common in access control installations. LED feedback (red indicator, green flash) and audible buzzer provide real-time operational confirmation without requiring additional signaling hardware. The black finish and STD-1 mounting ensure compatibility with standard access control enclosures and wallplate installations. Optional tamper detection supports security monitoring requirements in sensitive access control applications. The module's compact RM40 form factor reduces installation space while maintaining full feature support across all credential and protocol configurations.
