Overview

The First Alert SM110LED-AC is a hardwired smoke alarm designed to deliver timely alerts throughout your home. Integrated LED visual signaling pairs with a loud audible reminder, helping occupants notice smoke events even in noisy rooms or during sleep. The 10-year battery backup ensures continued protection during power outages without the need for frequent battery changes.

Key benefits

• Precision Detection helps minimize nuisance alarms from everyday cooking while maintaining early warning when smoke is present.
• 10-Year battery backup provides ongoing protection during outages, reducing maintenance interruptions.
• Integrated smoke alarm and LED strobe deliver a clear, visible alert for households with hearing impairments or in bright, noisy environments.
• Interconnect capability links with most First Alert and BRK alarms so that when one unit detects smoke, others respond for a coordinated warning.
• Test/Silence button enables quick checks and allows temporary silencing for up to 8 hours, helping you manage false alarms with ease.

Real-life use scenarios

In busy kitchens, the device aims to reduce cooking nuisance alarms while still providing reliable early warning when smoke is detected. During a power outage, the 10-year backup keeps the device active without swapping batteries. The LED strobe offers a tangible cue for individuals who rely on a visual alert, particularly in bedrooms or open-plan living spaces where sound alone might not be heard.

• Households with multiple devices can benefit from interconnectivity, ensuring a unified alert across rooms.
• Hearing-impaired residents or rooms with background noise gain a clear visual indicator in addition to the audible alarm.
• Users can perform routine testing and temporarily silence alarms up to 8 hours to focus on daily activities without losing protection.

Ease of installation and ongoing reliability

Designed for seamless hardwired installation, the SM110LED-AC combines compact form with robust signaling. The built-in 10-year backup and slide-in interconnect compatibility support ongoing safety across the home, helping you plan with confidence rather than guesswork.
