Overview

The BRK SC9120B is a hardwired combination smoke and carbon monoxide alarm that protects your home with two hazards in one compact device. It includes a 120-volt AC connection and a 9-volt battery backup, so warnings continue during power outages. A quick plug-in power connector makes installation straightforward, and a microprocessor helps limit nuisance alarms for a calmer, more reliable alert system.

Two-hazard protection with clear, distinct alerts

Carbon monoxide is colorless and odorless, so separate visual and audible warnings for smoke and CO help you distinguish the situation at a glance and respond appropriately. The unit provides dedicated indicators for the initiating alarm, reducing confusion during an emergency.

Interconnected safety for the whole home

With 120-volt AC interconnect capability, the SC9120B can link with up to 18 compatible devices, including up to 12 other alarms and six devices like bells, horns, repeaters, or door closers. If one alarm sounds, the entire network can sound to alert everyone in the home.

  • Superior carbon monoxide sensor and dual ionization smoke alarm
  • Simple to use silence/test button; separate smoke and CO latching alarm indicators
  • 9-volt battery included; 7-year limited warranty
  • Inter-connectable with BRK and First Alert hardwired smoke and carbon monoxide alarms
  • Easy to install universal mount bracket

Ease of use and reliability

A single test/silence button handles routine testing and silencing non-threatening alarms. The unit automatically performs internal self-tests to verify functionality, and a latching alarm indicator identifies the exact initiating unit. Tamper-resistant features include a battery drawer lock and mounting bracket lock.

  • Plug-in power connector for quick setup
  • Automatic internal test of functionality
  • Interconnected with up to 18 devices for broader coverage
  • Separate visual and audible warnings for smoke and CO
  • Power indicators show the current unit and status

Note: Follow local safety codes and consider placing CO alarms near sleeping areas, as recommended by safety guidelines. The BRK SC9120B is designed to offer reliable alerts across your home, contributing to safer everyday living.
