## Description

First Alert 10 Year Back Up Hard-Wired w/Battery Back-Up Ionization Smoke and Carbon Monoxide Detect

Review: Would buy again - We've had this brand since day one of home ownership. After 25 years, we replaced the whole house worth (7 units). Since we had these previously, it was easy to pull the old down and put the new up. It's a pain when the batteries start to weaken and the chirping begins in fire detection units, so these were a great option for us when it was time to renew.
Review: So easy - They provide 2 different power cables with adapters and one of them plugged into my existing power connection making installation very easy.

## Features

- First Alert's Precision Detection advanced sensing technology complies with new industry standards to reduce cooking nuisance alarms and provides early warning in the event of a home fire emergency
- 10-Year battery backup provides continuous protection during power outages

- Quick Connect Plug allows for easy installation with no need to rewire
- Alarm indicator visually identifies the unit that initiated the alarm
