First Alert BRK SMICO105-AC Hardwired AC Smoke & Carbon Monoxide Detector 10yr
First Alert BRK SMICO105-AC Hardwired AC Smoke & Carbon Monoxide Detector. This model has a 10 year factory sealed battery backup. Manufacturer’s date is June 24th, 2026 as you can see in the second picture. I purchased a lot of 6 of these but only required 5 of them. So this is a leftover, unused, new device that I didn’t need. Brand new but device was accessed to show the date of manufacture. Comes in original packaging with all original accessories in the same state as a store-bought device would be.
