The First Alert SC9120LBL hardwired smoke and carbon monoxide combination alarm with 10-year battery back-up features an ionization smoke sensing chamber and an electrochemical carbon monoxide sensor. The 10 year battery backup allows for continued monitoring, for the life of the alarm, even during power outages. Intelligent sensing technology is designed to reduce nuisance alarms and one button silences them if they do occur. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set off the alarm have subsided. An end-of-life signal enhances your safety by letting you know when it's time to replace the unit. Two locking features prevent battery tampering, and installation and connection to AC power is easy with the "quick-connect" wiring harness. Connect it to compatible BRK or First Alert alarms within a single-family residence and when one alarm sounds they all will.

  • 10-Year battery backup means constant monitoring for the life of the alarm even during a power failure

  • Features an electrochemical CO sensor and ionization smoke sensor

  • Indicator lights display the presence of smoke or carbon monoxide; an 85-decibel siren provides loud warning upon detection

  • Single test/silence button

  • Adapter plugs included for simple installation when replacing other branded alarms

  • Smoke and CO alarms should be placed on every level and in every bedroom of the home

  • Tested to meet UL standards

  • 10-Year limited warranty

Great quality, easy to set up.
Size: 3 Panels, Color: Grey, Size: 3 Panels, Color: Grey
I actually have this in my bedroom, replaced a non acoustic panel with it. These make a huge difference. As someone who is always playing music on their speakers I don't want to bother my roommates too much. Easily can hear the difference once these were in place. The panel itself is high quality and thick, what's a really nice detail is how they are attached together, there are multiple wedges just like foam noise dampeners which is super cool! This thing is easy to move around and can be folded for storage with ease. You get extra screws just in case you lose any, the feet are made out of metal which adds to the quality. There was a very slight chemical smell when taking it out the box, however that went away in just a few hours. I can imagine using this in a noisy office, surrounding yourself with these in a cube shape will make all the difference to focus on your work. These panels are great and if you're looking for quality, I'd say you can pick these up without worry. No issues on my end!

Office Divider
Size: 5 Panels, Color: Grey
This office divider is well made and easy to assemble. All you have to do is install the feet. The panels are only about an inch thick, but they work surprisingly well at muffling unwanted background noise.

Easily Create a Workspace
Size: 5 Panels, Color: Grey
Such a great design. I am loving the versatility of these - very easy to set up and also to store. THe color is perfect for them to blend into the decor. While they don't cancel out the noise altogether, they reduce it and decrease distractions. No installation needed - has its own supports. Built really well with good materials - sleek and sturdy and solid. They have increased the privacy and have helped make a great space without difficult construction. Work well and they are great value for money - instant privacy and space.

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.
