Kidde C3010 Carbon Monoxide Detector, 10-Year Worry-Free DC Sealed Lithium Battery Powered (21010073)

by Kidde


The Kidde C3010 is for a 10-year worry-free carbon monoxide (CO) alarm. It uses a lithium battery for power, which is sealed-in to prevent tampering. This battery has a 10-year lifespan, ensuring worry-free use until then. When at the end of its life, the battery makes a special chirping noise, notifying the homeowner that this unit needs to be replaced.

As this standalone Kidde alarm operates completely on the sealed-in battery, this model is incredibly simple to install. Affix the mounting bracket where desired and then attach the unit. Once connected to the mounting bracket, the alarm will activate the battery within. Plus, as there is no need for battery replacement, this model is practically maintenance-free for its 10 year lifespan. Once installed, this unit flashes a green LED light every 30 seconds to show that it is working properly.

This Kidde carbon monoxide alarm use electro-chemical sensing technology to detect harmful CO build-up. This alarm also has an event memory feature, which indicates with a flashing red LED light (with no beeps) when a high level of carbon monoxide was detected within the past 2 weeks. This allows homeowners to be aware of high CO levels even if they happen to not be present when high levels are detected. One additional perk of a battery-powered unit is that it operates even during power outages.
