I’m encountering issues with my Simplex 8650-440 (4010ES CPU Board and 2×40 LCD) fire alarm panel. The LCD display seems to be malfunctioning, and I’m not sure what steps to take to troubleshoot this. Can anyone provide guidance?
Sure! Here are a few troubleshooting steps you can try:
Check Connections: Ensure that all connections to the LCD display are secure. Loose connections can cause display issues.
Inspect for Physical Damage: Carefully examine the LCD display for any signs of physical damage such as cracks or water damage.
Power Cycle: Try power cycling the fire alarm panel by turning it off, waiting a few minutes, and then turning it back on. Sometimes, this can resolve display issues caused by temporary glitches.
Check Settings: Verify that the settings for the LCD display are correctly configured in the panel’s programming. Incorrect settings could cause display problems.
Update Firmware: If possible, check if there are any firmware updates available for the 4010ES CPU Board. Updating the firmware may address any software-related issues causing the display problem.
If these steps don’t resolve the issue, it’s possible that there may be a hardware fault with the LCD display or the CPU board itself. In that case, you may need to contact a certified technician for further diagnosis and repair.
