Other useful features include a self-testing alarm that monitors internal components, ensuring the detector is always operating as expected. It’s recommended to perform a manual button test weekly to verify alarm functionality. The 3 LED notifications—green for normal operation, amber for errors, and red for smoke or CO detection—are accompanied by an 85-decibel alarm for added safety. The test and hush button allows you to easily test the detector or silence false alarms. Backed by a 10-year limited warranty, this detector offers peace of mind, with the warranty beginning when the alarm is powered on. If the activation date is unknown, it is recommended to replace the alarm after 10 years of use.
