Kidde KN-COB-DP2 Carbon Monoxide Detector, AC Plug-In w/Battery Back-Up (21025761)

by Kidde


The Kidde KN-COB-DP2 is for a plug-in carbon monoxide (CO) alarm. This CO detector plugs simply into any standard wall outlet, making it incredibly easy to install. A light on this alarm turns green when it is plugged in and operational and turns red when the loud CO alarm is activated.

This Kidde plug-in CO alarm also features a 9-volt back-up battery. This ensures the functionality of this alarm when power is lost, which can happen in conjunction with incidences that cause dangerous carbon monoxide levels. Furthermore, this alarm has a tamper resist notification that alerts the consumer to potential theft, tampering and simple slippage of the unit from the outlet. A 6-pack of this unit can be purchased here - Kidde KN-COB-DP2 (6 Pack) - if you need CO detection throughout the home.
