Liftmaster K-S2W Rfid Wiegand Interface Module

Product Description

The LIFTMASTER K-S2W is an RFID Wiegand interface module designed to bridge RFID reader technology with access control systems that use the Wiegand communication protocol. It translates credential data from RFID readers into a standard Wiegand output signal, allowing legacy and current access control panels to receive and process card or fob credentials. Licensed electricians and low-voltage access control technicians are the primary installers of this module. It ships as a single unit and is categorized under smart reader devices.

This module is suited for commercial and residential access control installations where an RFID reader must communicate with a Wiegand-compatible control panel or gate operator system. Typical applications include entry points at commercial facilities, parking structures, and gated communities where credential-based access management is required. It is commonly integrated into door access systems, barrier gate controllers, and similar access control infrastructure that expects a Wiegand data format input.

Key Features

• Converts RFID reader output to standard Wiegand protocol signal
• Compatible with Wiegand-based access control panels and gate operators
• Supports credential-based entry management for commercial and residential sites
• Compact interface module format for straightforward panel integration
• Sold as a single unit for direct replacement or new installation use

Compatibility

Designed as an OEM-style interface module for use with Wiegand-protocol access control systems and RFID smart readers requiring a standard Wiegand data output.

Installation Notes

Installation should be performed by a licensed low-voltage or electrical technician familiar with access control wiring practices. De-energize the access control panel and any connected gate operator before connecting or disconnecting the module. Follow applicable NEC low-voltage wiring guidelines and the panel manufacturer instructions for Wiegand data line connections. Verify polarity and data line assignments at the control panel before restoring power.
