I know this sounds strange. We have electric smoke detectors. Are there batteries in them also? We have one that has started beeping and we can't stop it. Is there a battery in it or do we simply have to replace it? We have lived here 2 years (new) all the other batteries are OK. Our old house had electric smoke detectors and they never went bad. We lived there 15 years.

Have Electrician Check Smoke Detector
Sounds like there is a short somewhere. You need to contact a licensed electrician-he/she will have the tools and training to track down your problem. Do it as soon as you can because this could be a fire hazard; if you are on a very tight budget you can call the local fire department non-emergency number and ask if they know of any programmes in your area to help you.
Yes, there is still a battery. It's in case of a power outage for backup.
