I have 6 smoke and carbon monoxide kidde alarms hard wired and battery operated in series.The problem is they are going off without any smoke or carbon and the fire truck is showing up at my door.I noticed that some of the detectors have a blinking green light and some have continuous green light on. My question is should the light be on or blinking? How do I know when to chage the battery?

SOURCE: carbon monoxide detector err code

You are going to hate this as much as I did!
In the manual you will read this ..

Manual for Kidde Nighthawk C02 Detector
On page 13
----------------------------------
Unit Malfunction
In the rare event that your alarm malfunctions,
it will alert you with a short “chirp” and the red
LED will flash once every 30 seconds. The
digital model will display “Err” as shown in
Fig. 6.
Seven years after initial power up, this unit will "chirp" every
30 seconds to indicate that it is time to replace the alarm.
The unit will not detect CO in this condition. Please replace
immediately.

SOURCE: my kidde smoke and carbon monoxide alarm keeps

You will need to remove the unit from the ceiling to reveal the battery compartment on the back. It should just need to be rotated counter clockwise a small amount and will then come loose from the bracket. When installing a new battey be sure to press the battery reminder finger down into the battery compartment or the battery door will not close. Call the Kidde (pronounced kid-a) hotline if you have problems 1.800.880.6788

My Kidde carbon monoxide alarm keeps beeping every 30 seconds and we have put new batteries in it but it keeps beeping

Detecotrs have a limited lifespan of 5-7 years. So sounds like you need new one (Its not worth to buy just a sensor). Take a look on amazon Amazon com smoke alarm detector (watch out on reviews). I hope this was helpful. cheers

I have a Kidde combo smoke/carbon monoxide alarm and when my window air conditioner goes on the alarm goes off?

I assume your alarm is hard wired which should have its own circuit especially if there are any fluorescent lights on the same circuit.
