Sure! When troubleshooting an Edwards EST SIGA-DH smoke detector, start by checking the wiring connections to ensure they are secure and undamaged. Next, verify that the detector is receiving power by checking the voltage at the terminals. If the wiring and power supply seem fine, try cleaning the detector’s sensing chamber with compressed air to remove any dust or debris that may be interfering with its operation. If the issue persists after these steps, it’s possible that the detector itself is faulty and may need to be replaced. Always consult the manufacturer’s documentation for specific troubleshooting steps and safety precautions.
