First Alert SC9120B Hardwire Combination Smoke/Carbon Monoxide Alarm with Battery Backup 

Product Description

The BRK Hardwire Combination Smoke/Carbon Monoxide Alarm combines two safety features into a single alarm unit. This device detects both smoke and unsafe amounts of carbon monoxide in the air giving you maximum protection from fire and possible carbon monoxide (CO) poisoning. It is equipped with one of the latest sensing technologies enabling it to accurately detect CO levels in the air. This alarm unit also has a battery backup which ensures that it will still function and detect smoke and CO even during power outages.

CO is an odorless and colorless gas that is nearly impossible to detect without the help of an alarm unit. This gas is produced every time we burn fuel. Most CO poisoning cases happen at homes where there are a lot of possible CO sources which can include fire chimneys, gas furnaces, heaters, stoves, gas ranges, and other fuel-burning appliances and equipment.

Malfunctioning and poorly maintained appliances can leak deadly amounts of CO in the air. CO poisoning is very lethal and can kill an adult within a few minutes. In response to the growing number of CO poisoning deaths, the Consumer Product Safety Commission (CPSC) strongly recommends that every home should at least have one CO alarm unit installed in the main hallway or near the main bedroom.


Combination Carbon Monoxide and Smoke Alarm
The BRK Hardwire Combination Smoke and Carbon Monoxide Alarm warns you and your family of possible smoke and CO poisoning danger. It will send out a visual and audible warning every time it detects a possible danger.

Easy to Install and Inter-Connectable
This unit can be installed and plugged-in in any AC wall outlet in your home. In addition, the BRK CO and smoke alarm can be connected to other compatible smoke alarm units. It can be connected to as much as 12 smoke alarms and six warning devices such as horns, bells and door closers. This system ensures that you will still hear the alarm wherever you will be in your home. Interconnected alarm units mean that all devices will sound even if it’s only a single unit that originally detected a smoke or CO danger. The latching alarm indicator will identify which device detected the danger first.

State-of-the-Art Sensing Technology
The BRK Combination CO and Smoke Alarm is equipped with high-tech ionization sensors which can accurately detect and measure smoke and CO levels in any environmental condition.

Battery Backup and Battery Warning

Test/Silence Button
Whenever the alarm detects annoying non-threatening alarms, just press the silence button to stop it. This button also allows you to check if the unit is still functioning properly. It is recommended to check if the unit is still in good condition every month.
