Question About Nighthawk Carbon Monoxide Alarm KN-COP-DP

I have model KN-COB-DP that was in this house when we bought it about 7 years ago. Eight days ago we began to get an intermittent beep. I checked the unit and it was fine and never alarmed again until last nigth when it began producing the alarm again that indicates an error. Any ideas on what might be causing this?
