Phoebe and the Smoke detector

It's always so annoying to wake up at midnight because of a loud noise! Phoebe faced this problem when she wokeup with the smoke alarm beeping.She tried to turn it off but she couldn't. She disconnected it but it never stopped.Shw rolled it in a blanket and threw it in a rubbish chute.
After a while she heared a beeping sound coming from outside the door. She was surprised,  and she said "how did you come back". She opened the door when she heared a man's voice. She saw a fireman there he had brought back the smoke alarm.
She asked him how to stop the alarm from beeping and he told her there was a restart button. When he left she pressed the restart button many times after she found it under the table but the smoke alarm was wrecked.
This video shows that she never checked the smoke detector and she didn't care about it.But infact the smoke detector is so important as it may stop a big fire from happening. If there is any damage to a smoke detector you may not know there is a fire unless it becomes big and uncontrollable.
