The First Alert BRK SC7010BV Hardwired Talking Photoelectric Smoke and Carbon Monoxide Alarm detects both carbon monoxide and smoke in a single device. This 120-volt alarm features a photoelectric smoke sensor optimized to detect larger smoke particles from smoldering fires and an electrochemical carbon monoxide sensor for complete coverage.

The exclusive voice alarm technology alerts you to both the type of threat (smoke or carbon monoxide) and the location of the danger, with programmable location settings for up to 11 locations in your home. The 85-decibel alarm provides a clear, loud warning upon detection.

Designed to be hardwired into your home or office with battery backup for continued functionality during power outages (requires 2 AA batteries, included). The one-touch silence/test button makes it easy to operate, while indicator lights on the face display the presence of smoke or carbon monoxide. This kit includes universal adaptors for quick and easy installation with most existing First Alert, BRK, Kidde, and Firex alarms without rewiring.

The hardwired talking alarm can be interconnected with other compatible BRK and First Alert hardwired alarms for larger buildings, connecting up to 18 compatible devices (up to 12 smoke alarms and 6 compatible devices like horns and repeaters). Features end-of-life signal chirp and comes with a 10-year limited warranty.
