Description
10-Years of Uninterrupted Protection: The dual sensor smoke detector is easy to install and has a built-in 10-year sealed battery that provides continuous power for the life of the alarm. No need to worry about low battery chirps and the cost of battery replacements for a decade. The end-of-life warning will alert you when it is time to replace the detector. Dual Sensor Smoke Alarm: The SM310 10-Year Sealed Battery Dual Sensor Smoke Alarm features ionization and photoelectric smoke sensors to help provide protection from fast flaming and slow smoldering fires. Ionization alarms are generally more sensitive to fast flaming fires and photoelectric alarms are generally more sensitive to smoldering fires. Convenient Safety Features: Ensure the smoke detector is working properly using the single test/silence button located on the front of the alarm. See user’s manual for information on how and when to test and replace detectors. Help stop unwanted removal of the alarm using the optional locking feature.
