Sure, I’d be happy to help. Firstly, ensure that the detector is receiving power and that the wiring connections are secure. Check for any signs of physical damage or obstructions that may be interfering with its operation. If the detector still isn’t functioning correctly, try resetting it by power cycling the system. If the issue persists, it may indicate a faulty detector that needs to be replaced. Feel free to provide more details if you need further assistance.
