If your smoke alarm keeps randomly going off (even after dusting and cleaning the unit) chances are the alarm is more than ten years old and it needs to be replaced. Almost every smoke alarm manufacturer, as well as the National Fire Protection Association (NFPA), details that smoke alarm sensors go bad every ten years. Many homeowners neglect to replace hardwired smoke alarms as the wiring aspect can be confusing and dangerous. This video gives a better, in detail, understanding of how the replacement process works and shows that it can be done. If your not comfortable working with electricity I recommend contacting an electrician, or someone with more experience. I am not responsible for your actions.
