BRK SMI100-AC Interconnect Hardwire Smoke Alarm with Battery Backup

The BRK 1046844 (model SMI100-AC) is a hardwired, interconnectable ionization smoke alarm with a 9V battery backup. It suits installers and homeowners who want smoke protection that keeps working through a power outage and links with other First Alert and BRK hardwired alarms. A latching alarm indicator shows which unit triggered, which helps when you are tracing an alarm through a larger system.

Key features

• Wires directly into household power and uses a 9V battery backup to stay active during outages.
• Interconnects with most First Alert and BRK hardwired alarms, so every compatible alarm sounds when one does.
• Supports up to 12 smoke alarms and 6 other alarms on one interconnected setup.
• A latching indicator shows which unit started an alarm or reported a low battery.
• The mounting bracket holds the alarm securely across a wide rotation range, making alignment easier.
• A one-touch Test/Silence button lets you test the alarm or temporarily silence it.
