Kidde P3010K-CA Smoke Alarm, 120 V, Photoelectric Sensor, 10 ft Detection, 85 dB, Alarm: Audio, White

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. The P3010K-CA contains a 10 years 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 smoke alarm uses photoelectric sensing technology. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to help ensure maximum detection of the various types of fires that can occur within the home.
