1. Introduction
The Lenel LNL-1100-S3 Series 3 Input Control Module (ICM) is an integral component of advanced access control systems, designed to provide high-speed acknowledgement of critical alarm points within monitored areas. This module facilitates communication directly with an Intelligent System Controller (ISC) via either 2-wire or 4-wire RS-485 communication protocols. It features 16 configurable input control points and 2 output control relays, supporting various circuit configurations including normally open, normally closed, supervised, and non-supervised circuits. This manual provides essential information for the proper installation, configuration, operation, and maintenance of the LNL-1100-S3 module.

3. Setup and Installation
Proper installation is crucial for the reliable operation of the LNL-1100-S3 module. Ensure all power is disconnected before beginning installation.
3.1 Mounting
- Select a secure, dry location for mounting the module, away from sources of electrical interference.
- Mount the board using appropriate standoffs and screws to prevent short circuits and ensure proper ventilation.
3.2 Wiring
Connect the module to the Intelligent System Controller (ISC) using either a 2-wire or 4-wire RS-485 communication bus. Ensure correct polarity for all connections.
- Power Input: Connect 12 or 24 VDC power to the designated terminals. Verify voltage matches system requirements.
- RS-485 Communication: Connect the RS-485 data lines (TR+, TR-, GND) to the ISC. Use appropriate shielded cable for longer runs.
- Input Contacts: Wire the 16 input control points according to your system's alarm requirements. Configure for supervised or non-supervised circuits as needed.
- Output Relays: Connect the 2 Form-C output relays to the devices they will control (e.g., sirens, door locks).
- Tamper/Power Failure: Connect dedicated inputs for tamper switches and power failure monitoring.
3.3 DIP Switch Configuration
Set the DIP switches on the module to assign a unique address. Refer to your system's documentation for specific addressing schemes and ensure no two modules share the same address on the bus.
4. Operating Instructions
Once installed and configured, the LNL-1100-S3 operates under the control of the Intelligent System Controller (ISC).
4.1 Power-Up Sequence
- Apply power to the module.
- Observe the status LED. A steady or flashing LED indicates proper communication with the ISC. Refer to the ISC manual for specific LED patterns.
4.2 Input Monitoring
The module continuously monitors the status of its 16 input control points. Changes in input status (e.g., a door opening, a sensor triggering) are immediately communicated to the ISC.
4.3 Output Control
The ISC sends commands to the module to activate or deactivate the 2 output control relays. These relays can be programmed to respond to specific events or manual commands from the access control software.
4.4 Elevator Control
For elevator control applications, the module interfaces with the elevator system to manage access to up to 128 floors based on credentials and system programming.
5. Maintenance
The LNL-1100-S3 module is designed for long-term reliability with minimal maintenance. However, periodic checks are recommended.
- Visual Inspection: Periodically inspect the module for any signs of physical damage, loose connections, or corrosion.
- Firmware Updates: Consult LenelS2 documentation or your system integrator for information on available firmware updates. Updates should only be performed by qualified personnel.
- Cleaning: If necessary, gently clean the board with a soft, dry, anti-static brush. Do not use liquids or abrasive cleaners.
6. Troubleshooting
This section provides basic troubleshooting steps for common issues. For complex problems, contact technical support.
- Module Not Communicating:
- Check power connections and ensure correct voltage.
- Verify RS-485 wiring for correct polarity and continuity.
- Confirm DIP switch address settings are unique and correct.
- Check the status LED for diagnostic indications.
- Input Not Responding:
- Inspect wiring to the input device for breaks or shorts.
- Verify the input device is functioning correctly.
- Check configuration settings in the access control software for the specific input point.
- Output Relay Not Activating:
- Ensure the controlled device is properly wired and powered.
- Verify the output relay's configuration in the access control software.
- Check for any system alarms or conditions preventing activation.
