Smoke Alarm · 120V Hardwired · 10-Year Sealed Battery Backup · BRK SM6W10A
120V AC hardwired smoke alarm with 10-year sealed battery backup for operation during power outages. Suitable for single-station or interconnected residential installations, with support for up to 18 compatible BRK/First Alert devices total, including up to 12 smoke alarms; always confirm local code and device compatibility before replacement.
What this product is for
The BRK SM6W10A is a 120V AC hardwired smoke alarm with a 10-year sealed battery backup for residential warning systems. It is designed for use as a single-station alarm or as part of an interconnected alarm circuit so that when one compatible unit activates, all connected units sound.
Use for
Use for hardwired smoke alarm replacement or new residential installations where a 120V alarm with backup power is required. Commonly used in houses, apartments, condos, hallways, bedrooms, and other code-governed living spaces where compatible BRK or First Alert interconnection is needed.
Avoid for
Avoid using this unit where a carbon monoxide alarm is required, where a photoelectric-only alarm is specified, or where local code requires a different sensing technology or product series. Do not assume base or harness compatibility with every older BRK unit without checking the manufacturer documentation.
Best for
Best for electricians and property maintenance teams replacing older BRK hardwired smoke alarms with a model that keeps backup power sealed inside the unit for up to 10 years. It is also a practical choice where interconnected operation is needed across multiple alarms on the same circuit.
Installed in
Typically installed on 120V AC, 60 Hz residential alarm circuits in detached homes, multi-residential suites, rental units, and renovation projects across Canada. The alarm body is approximately 5.7 in diameter x 2.3 in deep (145 mm x 58 mm), which helps when planning replacement clearance at the ceiling box.
Why this product exists
This model provides hardwired smoke detection with backup protection during outages without requiring routine 9V battery changes. For service contractors, that can reduce nuisance maintenance calls compared with replaceable backup battery models.
Compared with similar products
Compared with basic hardwired smoke alarms, the 9120LBLA adds a sealed 10-year backup battery. Compared with combo smoke/CO alarms, this is smoke-only, so it is selected when carbon monoxide detection is handled separately or not required at that location. As typical guidance, interconnected alarms are commonly used to improve whole-home notification, but actual layout and required device count depend on the dwelling design and local electrical and fire code.
Actual performance and code compliance depend on installation conditions, device mix, wiring layout, and local requirements.
