Black is hot. White is ground. Red is interconnect.

Make sure to only use a brand name alkaline 9 volt battery. Don't use a used battery or a dollar store battery (bargain store). Then press the test button for 10 seconds to reset this unit and any more down the line.

All smoke detectors need batteries often. The voltage must be 1.5 volts higher than what the voltage says on the battery used. Also electronics these days are touchy that you only use alkaline. So buy a new brand name alkaline that hasn't been on the shelve very long. Never use a used battery from another device in the house. Never buy the cheapest deal battery from a dollar store etc. Once the battery is replaced press the test button for 10 to 15 seconds to reset all. If you don't press the test button it may continue to beep or warn you. If you press the button just enough to test the alarm it may not reset properly. The longer 10 to 15 second test usually solves all issues.

The chirp means the battery you chose wasn't good enough... it has to be the newest '''alkaline''' you can get hold of. If it isn't alkaline that's why you are having trouble. Upon replacement press the button to do a hard reset.

Make sure batteries are good, or maybe loose wires connection.
