Sure thing! When troubleshooting the Edwards EST SIGA-OSCD, start by checking the device’s connections and power supply. Ensure it’s properly connected to the fire alarm control panel and that there are no loose wires or damaged cables. Next, inspect the device itself for any visible damage or signs of wear. If everything appears to be in order, try resetting the device by power cycling it. If the issue persists, consult the device’s manual for specific troubleshooting steps or contact Edwards technical support for further assistance.
