So three times now out of nowhere, an alarm has started essentially wailing nonstop for about five to ten minutes at a time. I have no idea why, or what alarm it is. There were no appliances on aside from the heating. I live in an apartment with a fire alarm and a carbon monoxide alarm. The most recent time, I pressed the silence button on both and nothing happened, it just kept going off for another few minutes. The battery wasn't even in the fire alarm the last time and I have no idea if these alarms are going off somehow or if it's something else. It's very loud and annoying and the fact that I have no way of silencing it so all the neighbors get to endure this too is equally annoying. Any idea what it might be? I don't want to have to call the apartment maintenance if it's something I can fix.
