First Alert SMICO100-AC 2-In-1 Interconnect Hardwire Electrochemical/Ionization Smoke & Carbon Monoxide Alarm

First Alert SMICO100-AC, Interconnect Hardwire Combination Electrochemical/Ionization Smoke & Carbon Monoxide Alarm with Battery Backup.

Install this hardwired smoke and CO detector as a single alarm or interconnect multiple together to create an alarm system throughout your home.

All connected alarms will sound when one in the series is alerted to help provide an early warning.

Integrate with up to 12 other First Alert or BRK alarms and 6 other compatible devices.

Please reference user's manual for compatible detectors.

If the detector system sounds, the latching alarm indicator will visually identify the device that initiated the alarm.

Includes an adapter plug that allows for easy installation.

This can also be used for replacing existing hardwire alarms.

The 8th generation alarm is also equipped with a battery back to provide continuous protection during power outages.

Help stop unwanted removal of the detector or backup battery using the optional locking features.

Ensure the hardwired combination alarm is working properly using the single test/silence button located on the front of the device.

A low battery warning will let you know when it's time to replace the backup battery and an end-of-life warning will let you know when it's time to replace the detector completely.

See user's manual for information on how and when to test and replace 8th generation detectors.

First Alert's Precision Detection Advanced Sensing Technology meets the latest safety standards set by UL 217 8th Edition.

This means this combination alarm is better at distinguishing between harmless cooking smoke and real fires.

Additionally, 8th edition alarms can detect smoke from burning synthetic materials, which are common in modern homes.

This translates to fewer bothersome false alarms and a crucial early warning in case of a fire emergency.
