I simplified the IOP software sus watchdog alarms, only alarming on the DACKILL status. I added all missing SUS and SEI systems (the current system was essentially the Y-arm one-arm-test version). I found some IOP safe.snap files had incorrect alarm levels, which I fixed and updated all safe.snap files as some were RCG2.7 versions.

I added guidance text to the alarms.

IOP Watchdog alarms should now be valid and acted on if raised.
