Hello All. I have a smoke detector that I can't seem to get working right. When I replaced the batteries, the detector SMKT3-345 flashes Red Yellow Green, pauses for a while then Red Yellow Green over and over.

The manual only talks about the Yellow light indicating status or problems. What's going on?

Also, when I push the TEST/HUSH button, the alarm goes off but doesn't stop whether I let it go or push the button again. I wind up having to remove the batteries in order for it to stop going off.

Any help would be appreciated!
