## Overview

The FIRST ALERT BRK SC7010B-3 is a 3-pack of 120V hardwired combination smoke and carbon monoxide detectors featuring photoelectric and electrochemical sensors.

Designed for easy installation and minimal false alarms, they are the trusted choice for modern home safety.

## Description

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. Faster turnarounds on job sites with the easy-to-install, most-trusted alarms in home safety

Review: This is the current standard. They are ubiquitous. - There are competitors, but this is a very standard combo unit, especially for residential installation. When houses are not wired for smoke/CO2 detectors, people install battery powered units, but these units only have the batteries as backup for when the power goes off. Otherwise they run on AC power. This is more reliable, and the detectors are all connected, so when one is triggered they all let you know. There is discussion about the type of detector. In those discussions, this type of detector is sometimes preferred, especially for residential usage. I am describing a combo smoke/CO2 detector. CO2 detectors are now hardwired to expire. The expiration date is based on when you first pull the insullating tab that comes in it, and they last about eight to ten years. This is a safety feature and yes, they all have it. You will know you have reached that point when you hear the multi-beep warning. Two things to know: 1) If you reset it, it will give you about two days peace. If you pull it off the wall AND remove the battery, you will have peace without protection until you replace it. 2) If you have more than one in your house, you might as well replace them all at once. Generally there should be one outside the door to each bedroom, which in some houses is one unit, but in others more.
Review: Recommended for bedrooms, was very easy to install and sync. Just be sure to check the build date! - Overall, a very good unit, physically not obtrusive or annoying, just hangs on the wall watching for signs of a fire or high CO levels...barely notice it is there, until it goes off, but that's the purpose of its existence :-) Had an ionizing detector in our bedroom, kept going off whenever toast was burned in the kitchen on other side of house, LOL. (Full disclosure, we previously changed out the kitchen's to CO-only unit because smoke detection was not recommended in that zone, and it was a pure nuisance if doing anything beyond reheating something in the microwave...) After visiting the manufacturer's website, we found they recommended a photoelectric detector for bedrooms anyhow. Ordered this model because we have BRK/First Alert hardwired detectors in our house already, so their wiring plug was in place. Mounting base had to be changed, they are keyed by size to specific detector types so once installed, you don't rehang wrong type detector in the wrong area if you take any down for whatever reason...painting walls a different color is a good example of why one might temporarily remove a smoke detector. Really like the new broad spectrum sound for warnings, much easier on ears in general. Designed to not overload hearing aids yet still be detectable for people with hearing impairment. Can't couch for that part, but I can focus on getting safely out of my house when we do fire drills, instead of trying to cover my ears to stop the piercing pain, so it's a win for us :-) Safety advice: smoke detectors have a 10 year working life, and should be replaced accordingly per NFPA and BRK/First Alert's recommendations. With that, the first couple detectors we ordered on desertcart (specifically, from desertcart Warehouse Deals) were apparently rather old stock, having 2 and 3 years remaining before "expiration" and were each returned to desertcart with return comments that the respective unit was nearing end of NFPA's recommended effective life, should not be sold as "like new" when instead were *very old* stock -- 3rd one was a keeper, had a 2019 mfr date -- so word to the wise, check those dates for your own safety!

Easy installation and they work and look well. Be sure to change them at least every ten years.
