“WE HAVE SO MANY ALARM #1078 IN MCMU AND AFTER THAT AUTOMATIC MCMU SWITCHOVER AND THEN SYSTEM RESTART .HAVE YOU GOT ANY EXPERIENCE LIKE THAT?”
Most likely a software or hardware fault.
Would need further analysis.
Alarm history and check Computer logs to see if it gives you any clues.
Basic trouble shooting steps.
Do you get it for both MCMU or just the one MCMU?
Possible Quick Fix – You know you have temperamental MCMU’s so you cant risk loosing two during busy hours. Out of hours lock individual down and reload the software to MCMU from DSK. Do the same to both of them one at a time.
