New First Alert® Smoke and Carbon Monoxide Alarms Make Home Safety Simple
New alarms simplify maintenance and help keep smoke and CO alarms powered, active and ready to alert families
SCOTTSDALE, Ariz., Sept. 16, 2026 – Resideo Technologies (NYSE: REZI), a leading global provider of solutions for home comfort, safety and security, today announced a new lineup of First Alert® smoke, carbon monoxide (CO) and combo alarms. From America’s No. 1 most trusted and reliable* fire safety brand, the new alarms simplify home safety with easy installation, hassle-free battery replacement and the introduction of SoftCue™ Replacement Reminders, gentle maintenance reminders designed to help reduce late-night “chirps” commonly associated with residential smoke alarms.
“Resideo’s new First Alert smoke alarms redefine how to address everyday maintenance needs, which can help ensure our critical life-safety alarms remain powered, active and ready to alert families to smoke and CO threats,” said Ryan Park, Senior Product Director of Safety and Security at Resideo. “Too often, routine maintenance frustrations can lead homeowners to ignore or disable their alarms, and our simple but meaningful changes make home safety easier to manage while helping families maintain protection.”The redesigned First Alert alarms comply with the Underwriter Laboratories’ latest industry standards and offer features designed to simplify ongoing maintenance and operation, including:
- SoftCue Replacement Reminders. Gentle reminders pre-warn three to five days before the alarm needs attention with a soft sound and clear LED indicator, providing homeowners early notice when a battery is low or an alarm is nearing the end of its life.
- Easy-read indicators. Dedicated LED lights provide clear visual notifications that help homeowners quickly identify power status, a low battery, when the device needs to be replaced and whether a smoke or CO alarm has been triggered.
- Simple installation. A standardized ceiling bracket simplifies installation and future replacements, while an optional Easy-Fit Mounting Plate helps avoid repainting ceiling marks.
- Large, easy-access test/silence button. A centrally located Test/Silence button, nearly three times larger than previous models, provides convenient access for routine testing and temporary alarm silencing.
- Side-load battery drawer. Designed for easier maintenance, battery-powered and hardwired with battery backup models allow homeowners to replace AA batteries from the side of the alarm.
Advanced and Connected Detection
The new smoke, CO and combo alarms combine advanced detection technology with compatibility across the First Alert portfolio to help create a more connected home safety system. Every alarm features Precision Detection™ advanced sensing technology, designed to provide earlier warning of fires in modern homes, where contemporary building materials and furnishings can burn hotter and spread faster. It helps reduce nuisance alarms from cooking smoke and steam, delivering more reliable detection and greater confidence in everyday use.
Compatible hardwired models are designed for backward compatibility and interconnection with select legacy First Alert installations, enabling easier installation and replacement without additional adapters. The new lineup includes hardwired, battery-powered and 10-year sealed battery smoke, CO and combo alarm models starting at $29.99 (U.S. MSRP). Find a U.S. or Canadian retailer at FirstAlert.com.
Fire Safety Events and Education
Arriving just ahead of Fire Prevention Week, the new First Alert alarms are available now exclusively in the U.S. at Lowe’s stores. Lowe's stores nationwide will host fire safety events on Saturday, Oct. 17, to educate families about the importance of whole-home safety and celebrate first responders. From 10 a.m. to 1 p.m. local time, stores will welcome local first responders and emergency vehicles, giving families the opportunity to meet local heroes, explore fire trucks and equipment and learn how they help keep communities safe.
As part of the Oct. 17 events, kids can also build their own firefighting plane during a special Lowe’s Kids Workshop at Lowe’s stores across the country, combining hands-on fun with safety education and community connection. Learn more at Lowes.com/KidsClub.
The National Fire Protection Association (NFPA) recommends smoke alarms in every bedroom, outside sleeping areas and on every level of the home, including the basement. Families are encouraged to take simple steps to strengthen home safety, from maintaining working smoke and CO alarms and keeping fire extinguishers on hand to creating and practicing a family exit plan. Additional fire-safety tips available on First Alert's Safety Corner blog.

Frequently Asked Questions: Resetting, Beeping, Replacement, Hardwiring, and Differences
How do I reset a smoke and carbon monoxide alarm after it goes off?
After the area is safe and the cause is addressed, press and hold the Test/Silence button on your First Alert smoke and carbon monoxide alarm for 10–20 seconds until it chirps and the LEDs cycle. For battery models, you may remove the battery, press the Test button to discharge, reinsert fresh batteries, then test. For a First Alert hardwired smoke alarm or hardwired combo unit, turn off power at the breaker, detach the unit, press Test to drain, reconnect the harness, restore power and test. Always consult the user guide for your specific First Alert smoke alarm, First Alert carbon monoxide alarm or First Alert smoke and carbon monoxide alarm model.
What does a continuous beeping sound from a smoke and CO alarm mean?
A steady or recurring chirp typically indicates maintenance is needed—low battery, end-of-life, sensor failure or wiring/power issues on a First Alert hardwired smoke alarm. The new SoftCue™ Replacement Reminders and easy-read LEDs help identify the cause (low battery, service or end-of-life) on your First Alert smoke alarm or First Alert smoke and carbon monoxide alarm. Continuous alarm tones (not chirps) mean smoke or CO has been detected; move to fresh air, investigate safely and call emergency services if needed. On a standalone First Alert carbon monoxide alarm, follow CO safety guidance immediately.
How often should a smoke and carbon monoxide alarm be replaced?
Replace alarms at the end of their rated service life—generally every 10 years for smoke alarms and 5–10 years for CO sensors, per the product label. The LEDs and SoftCue™ Replacement Reminders on your First Alert smoke and carbon monoxide alarm indicate when replacement is due. Regularly check manufacture dates and replace First Alert smoke alarm and First Alert carbon monoxide alarm units on schedule to maintain awareness.Can a smoke and CO alarm be hardwired into my home's electrical system?
Yes. The line includes hardwired models, including a First Alert hardwired smoke alarm and hardwired combination units with battery backup. Compatible hardwired models can interconnect with select First Alert and BRK devices so that when one First Alert smoke and carbon monoxide alarm senses danger, all connected units sound. Professional installation is recommended if you are unfamiliar with electrical work or where required by regulation.
What is the difference between a smoke alarm and a combination smoke and CO alarm?
A First Alert smoke alarm is designed to detect smoke from fires; a First Alert carbon monoxide alarm detects CO from fuel-burning appliances and vehicles. A First Alert smoke and carbon monoxide alarm combines both sensors in a single device to help save space and simplify maintenance, while offering distinct LED/status alerts for each hazard. Choose a mix of single-function and combo units—or a First Alert hardwired smoke alarm paired with CO alarms—based on room-by-room needs and local codes.
