We know how important it is to keep your home and loved ones safe. That’s why we designed the BRK First Alert Hardwired Smoke & Carbon Monoxide Alarm to provide reliable, dual protection against two of the most dangerous threats to your home. This alarm combines advanced technology with user-friendly features to ensure your peace of mind.
Our alarm uses a photoelectric smoke sensor and an electrochemical carbon monoxide sensor, which are among the most accurate and reliable technologies available. This ensures early detection of both smoldering fires and dangerous CO levels.
We’ve made installation and maintenance as simple as possible. The mounting bracket features a large opening for easy access to wiring, and the side-load battery compartment lets you replace the battery without removing the unit from the ceiling or wall. Plus, the included dust cover protects the alarm during installation.
Yes, this alarm is interconnectable with other compatible units. If one alarm detects smoke or carbon monoxide, all interconnected alarms will sound, providing whole-home protection.
We recommend testing the alarm once a month to ensure it’s functioning properly. Use the mute button to test the alarm’s sound and indicators.
If the alarm sounds, evacuate your home immediately and call emergency services. The latching alarm indicator will help identify which unit detected the danger.
The 9V battery backup is designed to last for several years, but you should replace it as soon as you hear the low-battery chirp or when the end-of-life signal indicates it’s time for a replacement.
With the BRK First Alert Hardwired Smoke & Carbon Monoxide Alarm, you’re not just buying a device—you’re investing in the safety and security of your home. Trust us to keep you protected.
