Sure, troubleshooting the Edwards EST 2-LCD Fire Alarm Display can be relatively straightforward. Firstly, check the display for any specific error code or message. This will give us a starting point. If there’s no clear indication, begin by checking the power supply to ensure it’s functioning correctly. Next, inspect the wiring connections between the display and the main control panel. Loose or damaged connections can often cause display issues. If everything appears to be in order externally, the problem might lie within the internal components of the display unit. In that case, it’s advisable to contact a qualified technician for further diagnosis and potential replacement of faulty components.
