Firstly, ensure that the detector is securely installed and connected to the appropriate power source. Check for any visible damage or obstructions that could be affecting its performance. If everything looks intact, try cleaning the detector with compressed air to remove any dust or debris that may be interfering with its sensors. Additionally, check the wiring connections to ensure they are secure and not damaged. If the issue persists, it may be necessary to test the detector using a compatible testing device or consult the manufacturer’s guidelines for further troubleshooting steps.
