Sure! First, ensure that the power supply to the Edwards 435-6G1 is functioning properly. Check for any loose connections or blown fuses. Additionally, inspect the wiring to see if there are any visible damages. If the power supply seems fine, check the status of the batteries if it’s a battery-operated system. Sometimes, a simple battery replacement can solve the issue. If these steps don’t resolve the problem, it might be a fault in the control panel or the alarm devices themselves. In such cases, it’s best to contact a certified technician for further diagnosis and repair.
