Question About BRK electronic Carbon Monoxide Alarm CO5120PDBN
BRK FIRST ALERT CO5120PDBN problem...

About once a week for the past month the direct connected unit starts to beep in fixed intevals all night. It says "bat" on the readout, but the back up 9 volt isn't even connected. I had to remove it from the wall to get some sleep, but now I'm afraid not to have a CO2 unit in operation. Any suggestions?
