Default Alarm system transformer + power supply (would both go bad at once?)

Yes. Voltage spike, lightning strike, leg dropped across from power
company, or some moron accidentally touching the neutral in the breaker box
to the other leg of the incoming power. They can cause both to fail. All
are sudden over voltage conditions.
