## 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: Easy setup and installation. - Easy installation. I had switched from Kidde to BRK and First Alert detectors. I was seeing too many reviews where Kidde seems to have a bunch of their detectors are going bad around within a few months time. The Kidde detectors I had were good without any issues. They lasted over 10 years. On this BRK model I like that the green that glows is kind of buried into the detector so it's not being overly bright. I have to get closer to the detector before can I see the green light. I like that the replacing the batteries doesn't require the detector to be removed from the mounting plate. Also with the two tone alarm it is much louder than just a since tone. Just pull on it and the battery holder slides out. I used Wago wire connectors to connect the wires just in case if I ever need to switch brand of smoke detectors in the future.
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.

### ⭐⭐⭐⭐⭐ Looks great, no problems. No "real" test yet, though.
*by M***S on November 3, 2017*

Almost a year ago now, I ripped out all of the smoke and CO detectors in my house. I replaced them all with hard-wired detectors during a home remodel in accordance with NFPA guidelines (e.g. one in every sleeping quarter, gathering area, outside the door of every sleeping area, bottom/top of every stair, etc). The hard part was crawling around in unfinished areas of the house to run wire everywhere: once I had 12/3 NM-B in every ceiling box, wiring up these detectors was quick and easy. Each detector has a base that screws onto the junction box. It is a plastic flange that covers a quarter inch or so around the box, helping to mask the edges of the paint job or any irregularities in the drywall cutting. The wire hardness snaps into the detector, which then twists onto the flange. It comes with a label where you can write the data of install for future reference. It looks great compared to your Home Depot special, where you are lucky to get more than two that are compatible with each other. So far I have had zero false alarms after 8+ months of being installed. They have done better than the old ones that nuisance tripped by frying bacon - and the new ones are installed close to the old ones. Hitting the test button, they all go off within a second or two and are LOUD. They could wake the dead, which is important because I may as well be dead when I am sleeping. A train could smash its way through the house and I would not wake up. These things are loud enough to make my ears hurt more than a rock concert. I have burned a few candles near them and they have not triggered, but have not tried with actual fires, e.g. burning a 2x4 close by. It seems like smoke detectors have gone downhill lately, but these seem to work well enough based on my own observation and on other reviews.
