First Alert Combination Smoke & Carbon Monoxide Detectors SMICO105-AC Editorial Review
** First Alert 10 Year Backup Hard-Wired Smoke and Carbon Monoxide Detector** The First Alert 10 Year Backup Hard-Wired Smoke and Carbon Monoxide Detector has garnered positive feedback for its dependable features and hassle-free installation, particularly for customers who are transitioning from older models. Many users appreciate the unit's hard-wired capability combined with a 10-year battery backup, effectively eliminating the nuisance of battery replacements and the associated chirping that signals low battery life. The product’s design allows for straightforward installation, often using existing wiring, which has proven beneficial for homeowners replacing outdated detectors. However, some users have noted that the sensitivity of the detector can be excessive, particularly in kitchen areas. Instances of the alarm triggering from normal cooking temperatures indicate a potential issue for those who frequently use their kitchen. Despite this drawback, most customers find the overall performance and safety assurance that the advanced features offer to vastly outweigh any minor inconveniences related to sensitivity. Overall, the First Alert smoke and CO detector has been well-received, especially by long-time users of the brand, and is Considered an ideal option for those looking to upgrade for reliability and peace of mind. **
