We utilize the "Local Alarms" pin-outs on the backplane of one node and connect to an external alarm notification device (A simple relay, light and beeper system). We've been using this for 4-5 years.
Recently our alarm device is no longer being triggered when there is a Remote Alarm. The TCC2 card LED will indicate a "REM" alarm but both the Remote visual and audible contacts on the backplane will not close, triggering our alarm system. The minor, major, and critical contacts work as they are supposed to. We have reset the TCC2 card but this did not help. We upgraded to Release 8.5.1 about 2-3 months ago, and just noticed this problem a few weeks ago.
Is this a issue with Release 8.5.1 or is there some other problem(s) we could be experiencing?
