There could be a few reasons why your Kidde EGCVRF strobe isn’t functioning correctly. Firstly, ensure that the power supply to the strobe is connected properly and that there’s no issue with the power source. Next, check if the strobe is correctly wired to the fire alarm control panel. Sometimes loose connections can cause the strobe to malfunction. Additionally, inspect the strobe itself for any physical damage or signs of wear that might affect its functionality. If everything seems in order and the strobe still isn’t working, it may be a faulty unit that needs to be replaced. If you’re unsure or need further assistance, it’s best to contact a qualified technician to diagnose and resolve the issue.
