Interconnect Hardwired Smoke and CO Alarm with 10-Year Battery Backup

Install convenient 2-in-1 protection against both smoke and carbon monoxide with the First Alert SMICO105-AC Hardwired Interconnect Smoke and CO Alarm with 10-Year Battery Backup. This combination alarm meets new industry standards and can interconnect with other compatible detectors to create a whole home alarm system to help provide an early warning.

Early Warning Interconnect

The SMICO105-AC Interconnect Smoke and CO Alarm with 10-year battery backup provides reliable 2-in-1 protection with superior features. The combo detector can stand alone or be interconnected with other compatible alarms to create an alarm system throughout your home. When one hardwired detector sounds, all connected alarms will sound to help provide an early warning to a fire or carbon monoxide emergency. Integrate with up to 12 other First Alert or BRK Detectors and 6 other compatible devices. Please reference user's manual for compatible alarms. If the interconnected alarm system sounds, the latching alarm indicator will visually distinguish the unit that set off the alarm.

Hassle-Free Installation

Using the hardwired quick connect plug, easily install and replace existing hardwired detectors with no need to rewire into your home's electrical system. The SMICO105-AC Interconnect Combination Smoke and Carbon Monoxide Alarm is designed for hardwired installation but also features a 10-year battery backup. This will help provide continuous protection in the event of a power outage. Prevent unwanted removal of the alarm using the optional locking feature.

Easy to Maintain & Test

The 10-year backup battery eliminates the need for battery replacements for a decade. Use the test/silence button to test the combination detector regularly to check that it is working properly and silence false alarms. Detectors don't last forever and the end-of-life warning will let you know when it’s time to replace the alarm all together. See user's manual for information on how and when to test and replace alarms.

What is the UL 217 8th Edition Smoke Alarm Update?

UL Solutions has updated its smoke alarm standards requiring smoke alarm manufacturers to meet new requirements by June 30th, 2024, to reduce nuisance alarms and detect smoke from synthetic materials. This update is known as UL 217 8th Edition and helps to improve fire protection for modern homes. As a leader and the most trusted brand in fire safety*, First Alert has introduced Precision Detection advanced sensing technology to meet new UL 217 8th Edition industry standards. First Alert Precision Detection Smoke Detectors and Combination Smoke and Carbon Monoxide Alarms are available for online purchase at the First Alert Store.

*First Alert Brand Trust Survey, March 2023 – Results are based on the responses of 1,043 adult homeowners, ages 25 and older, living in the United States who completed an online survey asking them to choose from six brands in the smoke, fire and carbon monoxide protection space.

Why Should I Use First Alert Precision Detection?
Our new advanced sensing technology complies with UL 217 8th Edition smoke alarm standards to reduce cooking nuisance alarms and provide an early warning in the event of a home fire emergency. Current smoke alarms will continue to provide protection until they reach their end of life. However, when it’s time to replace the smoke alarms in your home or you want to upgrade to the latest technology, look for Precision Detection to help identify compliant First Alert alarms. Smoke alarms should be replaced at least every 10 years.
What is the #1 Reason Why Smoke Alarms Are Disabled?
The #1 reason why people disable smoke alarms in their home is due to nuisance alarms caused by cooking or steam leaving them unprotected (NFPA). Almost 3 of every 5 home fire deaths result from fires with no smoke alarms or no working smoke alarms (NFPA) so it is important to install and maintain your home’s alarms. Installing 8th edition alarms equipped with Precision Detection and following proper placement of at least 15 ft. away from cooking appliances will help reduce nuisance alarms.
