Can you see which wires are connected to the power supply? Normally red and black would be used for low voltage power supply. Black is ground (-) and red is positive.

As i know the red wire represents the positive (+) connection, while the black wire represents the negative (-) connection. However, to ensure accuracy, it's always best to consult the installation manual or contact the manufacturer of your security panel or TELUS for specific wiring instructions.
