The Kidde 30CUAR Hardwired Smoke and Carbon Monoxide Detector with AA Battery Backup is engineered to help protect against two common household hazards. With over 25% faster smoke detection*, it helps ensure early warning of fire or carbon monoxide by sounding a loud 85-decibel alert. This alarm features green, amber, and red LED lights that clearly signal power and alarm status. Advanced sensing technology reduces nuisance alarms, while a Test/Hush button allows for quick function checks and temporary silencing. Designed for simple setup, it includes an easy twist-and-click mounting bracket for seamless installation. For whole-home detection, its interconnect capability** allows multiple Kidde alarms to sound simultaneously; when one detects danger, all interconnected alarms sound together. Powered by 120V AC power, the device includes two AA batteries to help ensure continuous operation during power outages. Ideal for homeowners and safety professionals, this ETL Listed detector meets UL 217 10th Edition, UL 2034 5th Edition, and FCC standards. It is backed by a 10-year limited warranty*** from the date of purchase. *29% faster average smoke detection based on internal testing of smoldering wood fires for Kidde 9th Edition vs. leading competitor 8th Edition products. **Different models offer different interconnection options and requirements. Check the User Guide for more info. ***10-year limited warranty on alarm. Not a battery performance claim.

Q: Are the 30CUAR's compatible with other earlier models of the interconnected, smoke and CO, battery backup alarms that are still in service in your home? Are the same wiring harness plugs used?

1 Answer

A: Hi Neighbor! Yes, these alarms are designed to be interconnected, so when one sounds, they all sound. While they can replace earlier units, you may need to use a necessary adapter to connect the device to your original hardwire connection.

Installation was simple! The setup and functionality was very intuitive. All materials were as described in the details. Alerts (tested) sound as you would expect.

Easy installation

10 months ago

Replaced two units that had reached the end of the line . Using the required necessary adapter to connect to the original hardwire connection took about 2 minutes to remove the old unit, plug in the adapter to the device and the wiring , activating the included AA batteries and attaching the device to the ceiling mount. They functioned immediately and no problems with false alarms

Yes, I recommend this product.

Just had a remodel completed and these models were installed. False alarms in the middle of the night and randomly during the day. Replacing all of them because they are GARBAGE.

No, I do not recommend this product.

Thanks for your message and for reaching out to Kidde. Nuisance alarms can occur for different reasons which include common things like —cooking, aerosols, steam, or dust entering the sensor. Here are some tips to help solve this… you can use the Hush feature if safe to do so (i.e., confirming there is no actual fire), clean the alarm thoroughly with compressed air into sensor openings, and ensure it’s placed away from kitchens and bathrooms, as well as HVAC vents and fans. If the behavior continues after cleaning and relocating, please contact 1-800-880-6788 for additional support or replacement options.
