3. Product Overview

The LNL-1320-S3B module is a printed circuit board designed for robust access control applications. It features multiple connection points for readers, inputs, and communication interfaces.

Image 1: LenelS2 LNL-1320-S3B Dual Reader Interface Module. This image displays the red circuit board of the LNL-1320-S3B module. Key components visible include terminal blocks for 'READER 1' and 'READER 2' connections at the top left, indicating reader interface points. Below these, a series of smaller terminal blocks are labeled 'INPUTS', providing connections for various sensors or switches. On the right side, a larger terminal block is designated 'RS-485' for serial communication. The board also features several integrated circuits, resistors, capacitors, and other electronic components. A label near the center identifies the module as 'LENELS2 LNL-1320-S3B' with regulatory markings (UL, FC, CE). Another label indicates 'HID GLOBAL PCB-08558 REV-A'. Power input points are also visible, including '12V PT' and '5V' markings.

Key Features

• 12 or 24 VDC power supply compatibility.
• Supports Data1/Data0, Clock/Data, Supervised and Unsupervised F2F, and OSDP-compatible RS-485 readers and keypads.
• Supports Open Supervised Device Protocol (OSDP) readers, including biometric template transfer and Secure Channel encryption.
• On-board regulator allows 12 VDC reader support from a 24 VDC power source.
• Downloadable firmware for future updates and enhancements.

4. Setup and Installation

Proper installation is crucial for the reliable operation of the LNL-1320-S3B module. Follow these guidelines carefully.

4.1 Mounting

Mount the module securely within an appropriate enclosure, ensuring adequate ventilation and protection from environmental factors. Use non-conductive standoffs to prevent short circuits.

4.2 Wiring Connections

Refer to the module's labels and the diagram in Image 1 for correct terminal assignments. Ensure all connections are firm and properly insulated.

1. Power Connection: Connect the 12 VDC or 24 VDC power supply to the designated power input terminals. Observe correct polarity. The on-board regulator allows 12 VDC readers to be powered from a 24 VDC source.
2. Reader Connections (READER 1, READER 2):
   • For Wiegand readers, connect Data1/Data0 and Clock/Data lines to the corresponding terminals.
   • For OSDP readers, connect the RS-485 lines to the appropriate OSDP terminals.
   • Ensure proper shielding and grounding for reader cables to minimize interference.
3. Input Connections (INPUTS): Connect various sensors, door contacts, or request-to-exit devices to the input terminals. The module supports multiple inputs for comprehensive monitoring.
4. RS-485 Communication: Connect the module to the access control panel or network via the RS-485 terminals. This interface supports bidirectional communication, including OSDP Secure Channel encryption.

5. Operating Instructions

Once installed and configured within the access control system, the LNL-1320-S3B module operates by processing data from connected readers and transmitting it to the main controller. It supports various operational modes:

• Card Formats: The module supports up to 16 different card formats, including magnetic and Wiegand types, allowing for integration with diverse credential systems.
• Offline Access Modes: In the event of communication loss with the main controller, the module can operate in predefined offline access modes, such as lock, unlock, or facility code access, ensuring continued basic security functionality.
• OSDP Features: For OSDP readers, the module facilitates advanced features like biometric template transfer and secure, encrypted communication channels.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your LNL-1320-S3B module.

• Firmware Updates: Periodically check the LenelS2 support website for available firmware updates. Downloadable firmware ensures your module benefits from the latest features and security enhancements.
• Cleaning: Keep the module free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
• Connection Checks: Periodically inspect all wiring connections for tightness and signs of wear or corrosion.
