Kidde Worry-Free Living Area Smoke Alarm with Sealed Lithium Battery Power, Model P3010L

The Kidde P3010L is a 10-year, sealed battery, smoke alarm with photoelectric sensing technology and Smart Hush feature. The P3010H contains a 10-year tamper proof battery that eliminates the need for battery replacement, and ends worry over unauthorized battery removal. The alarm provides continuous protection from smoke and fire, even during power outages. This alarm uses photoelectric sensing technology. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Industry experts (such as the NFPA), recommend that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fires that can occur within the home. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms. The innovative design allows for automatic activation once the unit is attached to the mounting bracket; there are no pull-tabs, no switches, everything is automatic
At the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement
The customer can use a simple tool such as a screwdriver to deactivate the unit, stopping the chirp and making it safe for disposal.
