What caused the master alarm to go off in the movie Apollo 13?

The first is triggered by a Main Bus B undervolt, caused by the rupture of the tank containing oxygen which reacts with hydrogen to produce electricity. The second alarm is triggered when Main Bus A suffers the same problem. A third alarm is triggered by high levels of carbon dioxide, caused by the Lunar Module's inability to filter enough air for all three men for as long as it was being made to.

Why is your 92 vigor alarm going off when you unlock the drivers door?

This problem is actually caused by a bad lock actuator. You will need to replace the door lock actuator on the door lock that is causing the alarm to go off. I dont know why, but mine 93 Vigor does this as well. A tip: when u open the door and use the auto unlock, it turns the alarm off so you dont have to sit somewhere while u try to get the alarm to turn off.

The security alarm went off on your 2000 Montero Sport and would not turn off until the fuse was pulled and now the horn doesn't work - any ideas to fix it?

The alarm and the horn are interconnected in some models, if you pulled the fuse from the alarm it might have caused a surge big enough to blow the horns fuse, just replace it. You just have to make sure that the fuse you took from the alarm is back on. If the alarm is not working, disable it properly and not by removing a fuse.
