The BRK Electronics SMI105-AC smoke alarm provides reliable, long-term protection with a hardwired power connection and a sealed 10-year battery backup, ensuring continuous operation even during power outages—no battery replacement needed for a decade.
Designed with advanced ionization sensing technology, it delivers fast smoke detection and helps reduce nuisance alarms from everyday cooking. The latching alarm indicator clearly shows which unit triggered the alarm or is indicating a low battery condition.
This model is fully interconnectable with most First Alert and BRK alarms, allowing up to 12 smoke alarms and 6 additional compatible devices to sound together when one is triggered for whole-home protection.
A single easy-access test/silence button allows quick testing or temporary silencing of alarms. A built-in dust cover helps protect the unit during installation or construction.
