Sure! Firstly, ensure that the detector is correctly installed and powered. Check the wiring connections for any loose or damaged wires. If the detector is not responding, try resetting it by removing power for a few seconds and then restoring it. Additionally, ensure that the detector’s chamber is clean and free from any dust or debris, as this can interfere with its operation. If the issue persists, it may be necessary to replace the detector or contact System Sensor technical support for further assistance.
