Question about Kidde Kiddie - Nighthawk Kn-cob-lcb-a Fire Carbon Monoxide Alarm
Why is my 2 year old detector beeping 4 beeps with a pause and continue to do this? I had fire dept come check with no detection and the furnace repairman come in and we reset detector and it started beeping last night again after 4 day ago fire call
I'm pretty sure that indicates an alarm. The pattern is referred to as "temporal 4" which is the alarm pattern for CO. Either your device is in a bad place or there is an intermittent CO leak which is exceeding the ppm (parts per million) threshold for a given time period. The instructions for the device will tell you what that number is. If you have more than one of these, I would try swapping them to determine if the problen is with the device or the location. Good luck!

SOURCE: how to fix detector
You don't mention how old the detector is. If it is more than 5 years old the detector may be beeping to indicate the end of its service life. A smoke detector can last much longer but carbon monoxide detectors have a limited life span. If putting in new batteries doesn't fix the problem then most likely you will need to replace it.

My Smotec 3786A indicates not to install it in above 85% humidity.
One of my three seems to go off annually or so and this is what
recently put it down to. I was making an espresso coffee on the
stove and it generates a lot of steam and off goes the fire alarm.
I did change the battery to no avail.
