The FIRST ALERT SC7010B Hardwired Combination Photoelectric Smoke and Carbon Monoxide Alarm with Battery Backup delivers both smoke and carbon monoxide detection in a single unit. Equipped with a photoelectric sensor and Optipath 360 technology, the alarm detects smoke produced by smoldering fires while keeping false alarms to a minimum. The unit also features an advanced electrochemical sensor that detects carbon monoxide leaks from multiple sources such as faulty fuel-burning appliances and blocked chimneys. If a threat is detected, the alarm emits a spread spectrum horn tone that is designed to be heard by people with age-related hearing loss. Made to be hardwired directly into the electrical system of your home or facility, this 120-volt hardwired smoke detector features a backup battery that helps keep the alarm functioning even in the event of a power outage. The alarm’s perfect mount system allows for easy installation and alignment, while its low battery latch gives a visual indication if the battery is running low. And thanks to the convenient test/silence button, it is easy to check alarm function and mute false alarms.

Customers find the smoke and carbon monoxide detector to be of excellent quality and very easy to install. The reliability receives mixed feedback – while some say it works as advertised, others report it giving false alarms and going off randomly. The value for money and loudness also get mixed reviews, with some finding it a great value while others say it’s extremely frustrating for the price, and while some like how loud it is, others complain about the screeching sound. Durability is a concern, with multiple customers reporting units failing within a year of purchase.
