This sort of wiring guarantees that if one alarm in the house goes off, they all go off.

What happens if you don’t change the battery in a smoke detector?

A smoke alarm will eventually stop chirping if you do nothing. Once the battery has run out completely, the device will switch to residual power. Eventually, this will also drain and the device won't have enough power to beep and let you know it's out of power. You should change the battery before this happens.
