I just came to my room after having fallen asleep on the couch to find the smoke detector beeping every 30 seconds. One beep every 30 seconds. I took out the battery but it's still going. I pressed the button on it and it made the actual smoke alarm (piercing my ears in the process) but the beeping continues. I haven't slept for over a day, so... tired... Anyone know anything they wouldn't mind sharing to help alleviate this problem?
