How to Set Up Master Card

1. Step 1: Power off the unit. Connect the S1 jumper cap to pins 2–3, then restore power. Wait for the green LED to flash three times.
2. Step 2: Present two consecutive blank cards (the first card becomes the "Add Card," the second becomes the "Delete Card"). The red LED will flash rapidly, confirming setup.
3. Step 3: Power off again, reconnect the jumper cap to pins 1–2, then restore power. Your master card setup is complete.

How to Add or Delete Users

• Add User: In standby mode, present the "Add Card," then present each user card you wish to enroll, then present the "Add Card" again to exit.
• Delete User: In standby mode, present the "Delete Card," then present the user card(s) to remove, then present the "Delete Card" again to exit.
• Delete All Users: In standby mode, present the "Delete Card," then the "Add Card," then the "Delete Card" again to wipe all enrolled users.

Frequently Asked Questions

Q: What types of RFID cards are compatible with the LK-009 access control module?

A: The Asia-Teco LK-009 module supports both 125KHz EM/ID cards and 13.56MHz IC cards, giving you broad compatibility with most standard RFID access cards and key fobs.

Q: Can I manage users without a computer or special software?

A: Yes. User enrollment and deletion are managed entirely at the module itself using designated "Add" and "Delete" master cards. No computer, app, or additional software is required.

Q: What is the maximum number of users this module can store?

A: Please refer to the product datasheet or contact Asia-Teco directly for the maximum card storage capacity, as this may vary by firmware version.

Q: Is this module suitable for outdoor installation?

A: The LK-009 operates across a wide temperature range of -20°C to +60°C, making it suitable for many installation environments. For outdoor use, it is recommended to house the module in a weatherproof enclosure to protect it from moisture and direct exposure to the elements.

Q: What power supply does the LK-009 require?

A: The module operates on DC 12V with a working current of less than 100mA. A regulated 12V DC power supply is recommended for stable operation.
