we are equipped with NFS2- 640/E Fire alarm control panel including the MODBUS Gateway card.

“NCM Communication failure” alarm is frequently occurring (Everyday).This alarm is meant for communication failure between FACP and MODBUS gateway card.

For attending this problem we remove the jumper cable from FACP to MODBUS Gateway card and re-insert it and then we reset the FACP, with this communication goes healthy but next morning we found same alarm on FACP Display.

Any Solution...?

It seems to me that you would be well advised to be talking with the tech
support departments of the manufacturers involved.
