Additionally, there are some key points to consider during the installation of the interlocking door lock:
- Securely install the signal connection wires to the door latch and signaling light. Error Alert: The alarm will sound loudly and continuously.
- Align the door latch and latch positioning plate in the same direction (WiFi symbol) on both accessories. Error Alert: The latch won’t operate.
- Avoid reversing the signal wires between the signaling light and door latch. Error Alert: Installation failure. Note that the signal wire for the door latch is slightly thicker than the wire for the signaling light, so please take this into account during installation.
- Use wire protection boxes and tubing on the ceiling to protect signal wires from damage by insects. Signal wires are different from power wires and can be difficult to reconnect if damaged or severed.
