Kidde Kncob Dp2 Tamper Resistant Plug In Carbon Monoxide Alarm With Battery Backup Model: Kncob Dp2

Kidde Kncob Dp2 Tamper Resistant Plug In Carbon Monoxide Alarm With Battery Backup Model: Kncob Dp2

Q: What is the location of the wall plug on the device? Will it cover the entire outlet?

The plug also can be removed from the unit in case you want to mount the device on the wall or stand it on a table or night stand.

Q: How do you turn on the "low battery hush"?"

Not sure, but my suggestion would be to replace the battery. What good is a battery backup if your battery is low?

Q: When I unplug this device the green light goes off even though the batteries are installed as a backup. Is that normal?

When plugged into the wall outlet, it'll have a constant green light. When running on battery backup, it'll flash the green light every 60 seconds to indicate that it is still working and it'll flash red when the backup battery is low on power and needs replacing.

Q: When I try put battery in or plug it in, the alarm goes off! Does that alarm sound stop? It's brand new

My unit kept beeping every minute. The batteries were not put in correctly when I received the unit! The problem seems to have stopped for now.
