Yep this happens all the time, the transfer switch dies and then you are
screwed because you don't switch to backup power. Your UPS system then run
out of power and you are dead. That is why we are building a manual
maintenance wraparound around the UPS AND the transfer switch so that if
they switch does die you can manually have some guy bypass the switch.
