I am living in a house with 4 other students and the smoke detector is doing that beeping thing where it tells you it is out of battery, except it is 1 in the morning and I can't exactly buy a battery at this time and it is constantly beeping and I need to be up early in the morning, I have tried unplugging it but it doesn't want to come off and when I tried the fire alarm went off. I really need to sleep but with this beeping I can't, I know I shouldn't unplug it but I really need some sleep, does anyone know how to stop it from beeping? It is an Optical Smoke Detector but everything I have googled hasn't helped, can anyone help?!
