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 job by Asurion!
Asurion handled my claim quickly and efficiently. My return was picked up by UPS and an Amazon gift card for the full amount was received as promised. Very happy with the process.

Make sure you read the terms and conditions and don't let them off the hook
Asurion is counting on the fact that you don't know how to read. They made the claim process aggravating and as difficult as possible. I CAN read and had to review the terms and conditions with them on the phone and threaten to involve an attorney before they would honor the coverage. They tried to say my product was not portable, when the word "portable" is literally in the name of the product. Then they tried to say the the accidental drop was not covered, but it clearly states in the terms and conditions that an accidental drop and a cracked screen is a covered event. I buy the coverage almost every time I am offered it, but I will be rethinking that going forward and Amazon should consider finding a different company to issue the protection plans for their products because I fear this is the beginning of a lot of complaints. I have filed a claim in the past and it was very straightforward and easy, but they must have a new company managing the plans now, because it was anything but easy. If I was an older person who was not tech savy, or who just took someone's word at face value, I would be out the cost of my item and the protection plan. BUYER BEWARE

Cover yourself!
My HP printer just stopped printing. Spent over 4 1/2 with HP Support doing all kinds of technical experiments with even the most complex Factory Restarts, this printer kept saying everything was working but it wouldn't print. HP finally declared it a hardware defective; told I needed a new printer and to recycle this one (less than 1 1/2 years old - don't make like they used to!). Called Asurion, who immediately processed a claim and arranged for a pickup of the defective printer since I can't drive. Fast quality service worth every penny if you're buying any kind of devices in today's world.

Asurion is a great protection plan.
Asurion is a great product. I purchased a 3-piece cordless phones in 2022 and added the Asurion protection. Just recently the phones went out. I contacted Asurion and within 2 hours I had a gift card deposited in my Amazon account. I purchased new phones with the gift card and of course added the Asurion protection. I highly recommend Asurion protection plan.
