One small tip

Why does my smoke detector keep going off for no reason??

Mainly 2 reasons:

1. Dust on the sensors
   Ionization smoke detectors can mistake dust for smoke. So if your ionization smoke detector is covered in dust, that's why it sets off the alarm even if there's no smoke.

2.      Malfunctioning
         Your smoke detector may just be old and needs fixing. But smoke detectors are cheap. So chuck it and upgrade to   newer better smoke detectors. They've come a long way since the last time you bought them.
