As a technician from firealarm.com, I suggest checking a few common issues that could trigger the trouble light on your Silent Knight 6808 panel. Firstly, ensure that all wiring connections are secure and properly terminated. Loose or damaged wiring can often cause trouble indications. Next, check the power supply to the panel to ensure it’s within the specified voltage range. Sometimes fluctuations in power can cause issues. Additionally, review the panel’s event history to identify any specific trouble codes or events that may point to the source of the problem. If the issue persists after checking these steps, it may be necessary to consult the panel’s user manual for further troubleshooting or contact technical support for assistance.
