I just want to replace the battery in my kidde smoke combo detectitor!

Most modern detectors have a battery compartment right on the top in plain sight, but a few have the compartment underneath, while still fewer have no battery at all. For smoke alarms, if the unit is more than 10 years old the entire unit must be replaced; for CO, the time limit is usually less (5-7 years). The best way to know is to check the model number. Most units are removed by turning counterclockwise. The info you need to find whom to contact with questions should be underneath.

How do I troubleshoot an intermittent problem with a 2 wire system sensor smoke detector

Intermittent problems are often difficult even for professionals. That said, I would need more specifics on the problem if you want to continue on your own first. The model of the system, keypad indications, whether the problem is a trouble or alarm, what make/model the detectors are (there could be more than 1 type on a 2-wire fire zone), etc.

How to replace battery back-up in hard-wired ceiling mounted residential Firex Smoke Detector? Model number unknown but units about 10 y.o. - circular in shape and cream coloured.

Those battery holders are not easy to find on that model. However, look for a small screw on the outer perimeter of the detector. That's the door that needs to removed to replace the back-up battery. Some models don't have the screw, but can be popped open with gentle pressure using a flat tip screw driver.

Hope that helped to solve your problem.

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.
