i just bought some lockers from a garage sale and some of the lockers still have locks on them because the owners lost the keys to them and now i have to pop them off but i dont know how
There's dust in the alarm sensor. Clean it with condensed air.
Put different batteries in or Get a new smoke alarm. They are really easy 2 install
As you said, they are not speed bumps. They are called rumble strips, and get your attention if you are coming up on something that might be a hazard, or if you have wandered out of your lane.
It sounds like your house has interconnected smoke alarms ( the best in a large area) When you remove one the others can sense this and are telling you that something is wrong with the system. It would be in your best interest to have a fire alarm tech. check out your system. Remember Smoke Alarms save lives and please keep them in good condition.
