CO/Smoke Detectors

I hope that you have better luck than I - with a combo unit.

Went to store few years ago and purchase 3 brand name combo units. Hard wired units with backup battery.

All within three years malfunctioned. No way to stop the beeping. On all. Multiple new batteries of different brands and stores. No it was not one bad batch of batteries from a single store.

Changed tactics. Replaced all with standard hard wired smoke alarm. Then purchased separate carbon detectors that work by battery. No beeps since.
