Installation Diagram for the Three-Way Interlocking

• The interlocking lock control unit will be installed on the ceiling panel, connected to an available socket (the shorter the distance between the control unit and the socket, the better, to match the power cord accompanying the lock and save wiring costs).
• The signal light will be mounted on the wall panel, in an easily observable area when entering/exiting, usually installed next to the control room door.
• The door bolt will be concealed inside the ceiling panel (requires drilling and concealed wiring) and can be installed on the side or above the door frame.
• The door bolt positioning plate will be attached to the door leaf, corresponding to the location of the door bolt installation.

In addition, there are some important points to note during the installation of the interlocking lock:

1. Securely attach the signal connection wires to the door bolt and signal light. --> Error: The alarm bell will ring loudly and continuously.
2. Install the door bolt and the positioning plate in the same direction (WiFi symbol) on both accessories. --> Error: The door bolt will not function.
3. Reverse the signal wires between the light and the door bolt. --> Error: The installation is not successful. The signal wires of the door bolt are typically slightly thicker than the wires of the light. Please be cautious during installation.
4. Use wire protection boxes and tubing to protect the signal wires on the ceiling to prevent insects from damaging the wires. Signal wires are different from power cables and can be challenging to repair if they are cut or damaged.
