Experience the next level of fire safety with the Kidde Hardwired Smoke & Carbon Monoxide Detector, AA Battery Backup, Voice Alerts, Interconnectable, LED Warning Light Indicators, model 30CUAR-V. This smoke & CO detector has enhanced sensing technology that reduces false alarms often caused by cooking and sends fast alerts that help give your family more time to get out safely. To detect carbon monoxide, an electrochemical sensor is used. This alarm offers a modern 5-inch design ideal for all living spaces such as living rooms, hallways, kitchens, & bedrooms. Voice alerts clearly announce “Fire!” or “Warning Carbon Monoxide!” to help identify which hazard is detected. Comprehensively tested and designed to the latest UL standard for safety and reliability, the 5-inch smoke & CO alarm is powered by 120V AC wiring with 2 AA alkaline replaceable backup batteries (included) for continual detection even during outages. Batteries should be replaced every 6 months or when the alarm sounds a low battery chirp. In addition, it’s self-testing and easy to install with the included twist-and-click mounting bracket. Meets requirements of 9th Edition UL 217, UL 2034 4th Edition, FCC, and CSFM.

10-YEAR LIMITED WARRANTY: Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced
Customers find the smoke and carbon monoxide detector easy to use and appreciate its loud sound and voice alerts. However, the product’s reliability is mixed, with some saying it works well while others report frequent false alarms. Moreover, durability is a concern as units fail within 2-3 years, and the battery life receives mixed feedback, with one customer noting the 10-year battery backup feature. Additionally, the wiring and value for money aspects also receive mixed reviews.
