## 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: Great Product with Easy Installation - Just received two of these today, but I had to return one unit. Defective unit came in a box which had been taped on one end and the batteries were missing. Unit did not indicate that it was receiving A/C power (hardwired) when checking the green light on the face of the unit, although it was receiving battery power. Removed batteries, unit would not operate in any capacity at that point. Removed wire nuts to make sure wiring harness was making contact with existing wire in electrical box, looked to be in good order. Switched mounting locations to confirm that it was indeed an issue with the unit and not the power source or harness, but it still didn't work. Other unit was fine. Submitted return ticket with desertcart and I am confident it will be resolved quickly. Units were replacements for 18 year old ionization models. Changed mounting bracket and wiring harness easily. Units mounted easier to the installation brackets than older Firex units that they were replacing. Glanced at instruction and they seemed to be straight forward and easy to follow which would be a plus for anyone with limited electrical knowledge. Units came with dust covers which I thought was an excellent idea in case you are remodeling or this is going in new construction. This combination smoke and carbon monoxide alarm has two distinct alarms depending on which event is triggering the alarm. Battery access was simple, so changing out batteries would be a piece of cake. Definitely easier to access than the Firex models they replaced. Overall, I really liked this particular First Alert combination alarm. I will upgrade score depending on how the situation with the defective unit is handled. Update 8/27/2018: Went from 4 star to 5 star rating. Return/swap of defective unit was handled quickly and all units that were purchased have been operating perfectly.
Review: Looks great, no problems. No "real" test yet, though. - 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.

### ⭐⭐⭐⭐⭐ First Alert, a company that still cares about the environment
*by S***R on May 26, 2021*

Pros of First Alert Brand of detectors * Made in Mexico * Maintains a take-back hazardous waste disposal program - for ionization smoke alarms. * comparable pricing to other brands Cons: * Might need to change the hardwire and interconnect pigtails if replacing a different brand of smoke detector I replaced several FireX/Kiddie smoke & CO alarms with First Alert models SC7010B, SC7010BV, & BRK 3120B. Changing the power and interconnect pigtails isn't hard, but I purchased the First Alert BRK ADF-12 adapter plugs [ASIN: B0039PJK40] to make the process easier for the many alarms that I had. Each alarm took less than 10 minutes to replace. The process was straightforward: Replace the faceplate, connect the adapter plug and connect the First Alert smoke alarm. Easy-peezy! It's been only a short time since they have been installed, but no false alarms yet! Ionization smoke detectors contain a small amount of radioactive material (1 micro curie of Americium 241). The radioactive element should be disposed of at a radioactive waste facility. Some municipalities offer to dispose of the ionization alarms properly, while others to do not. As of Sept 2019, FireX/Kiddie discontinued it's take-back disposal program. The Kiddie website now states: "Typically, alarms may be disposed of in your regular, residential trash. Verify with your local municipality regarding disposal ordinances before disposing of an alarm." This is so egregious! Kidde isn't a responsible manufacturer when it comes to handling their product at end of life. What happens when your local municipality does not have a safe disposal program for the radioactive material in ionization detectors? Kiddie is flaunting that they simply do not care about the environment. That alone is the reason to purchase from First Alert instead of Kiddie - First Alert has continued to maintain its take-back hazardous waste disposal program. Think about the future generation when deciding which smoke detector to purchase! In the end, I'm happy with my purchase knowing I gave my money to First Alert, a company that still cares about the environment!!
