Setup Instructions
Connecting the 12V Electromagnetic Lock (EM Lock)
The prop is designed to work with a 12V electromagnetic lock. Ensure your EM lock is rated for 12V to prevent damage or malfunction. EM locks are not included with this product and must be provided separately.
- Connect the red wire of your electromagnetic lock to the NC (Normally Closed) port on the controller.
- Connect the black wire of your electromagnetic lock to the COM (Common) port on the controller.

Operation
Players interact with the prop by pressing the metal buttons. Each press cycles the button's LED through its 7 available colors. The objective is to achieve a specific color combination across all buttons. Once all buttons display the pre-configured colors, the prop will trigger, and the connected electromagnetic lock will open.
Configuration
Modifying the Color Settings (Trigger Password)
Follow these steps to customize the required color sequence for triggering the prop:
- Power Off: Disconnect the power adapter from the controller.
- Enter Settings Mode: Press and hold the Settings button (located next to the power port). While holding the button, reconnect the power adapter. Continue holding until you hear a voice prompt, then release the button.
- Set Colors: Listen for the voice prompt to end. Then, press each metal button multiple times until it displays the desired color for your new trigger sequence.
- Save Settings: Press the Settings button once more to save the newly configured colors. The controller will automatically reboot to apply the changes.
- Test: After reboot, test the prop with your new color sequence.

Modifying the Reset Mode
The reset mode can be adjusted using the settings switch (DIP switch) located next to the power port on the controller.
- Automatically Reset Mode: Set DIP switch #3 to the UP position. The prop will automatically reset after 1 minute following a successful trigger.
- Real-Time Reset Mode: Set DIP switch #3 to the DOWN position. The prop will reset immediately upon any button press after a successful trigger.
Modifying Voice Files
You can customize the audio prompts played by the controller:
- Connect to PC: Insert the USB cable into the controller and connect the other end to your PC.
- Backup Files: Open the removable disk that appears on your PC. It is highly recommended to back up all original files from the controller to your computer.
- Replace Audio: Replace the original audio file(s) with your preferred sound file(s). Ensure the new files have the exact same path and filename as the originals. The audio file format must be MP3. The total size of audio files should not exceed 16MB.
- Formatting (if necessary): If you need to format the removable disk, format it to FAT format only. Do NOT format it to FAT32, exFAT, or NTFS.
Resetting the Prop
There are three methods to reset the prop after it has been triggered:
- Automatic Reset: If configured, the prop will automatically reset 1 minute after a successful trigger.
- Real-Time Reset: If configured, pressing any button again after a successful trigger will reset the prop.
- Manual Reset: Power cycling the controller (disconnecting and reconnecting the 12V power adapter) will reset the prop.
