Hey there! Sorry to hear about the trouble you’re facing with your Edwards EST GCSVRF system. First things first, let’s check the power supply to ensure it’s functioning correctly. Sometimes, issues with notification devices can stem from power supply problems. If that checks out, the next step is to inspect the wiring connections. Loose or damaged wiring can definitely cause issues with device activation. Additionally, it’s worth checking the programming of the system to ensure that the notification devices are configured correctly and that any silence/reset functions are properly set up. If none of these steps resolve the issue, it might be time to call in a professional technician to perform a more in-depth diagnosis. Hope this helps!
