Question About Nighthawk Smoke Alarm KN-COSMXTR-8
My Nighthawk smoke alarm/CO detector just went off...

My Nighthawk smoke alarm/CO detector just went off. Not a fire or CO signal, just one long continuous signal--not a beep, a continuous signal. Hitting the reset button only turns it off for a half second. Had to remove battery. Why is it going off?
