The Kidde P3010H is a 10-year, sealed battery, smoke alarm with photoelectric sensing technology and Smart Hush feature. When smoke or fire is detected, the 85dB alarm tone is accompanied by illumination of bright LEDs to help provide a lighted escape path. The alarm will automatically activate when it 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 P3010H contains a 10-year tamper proof battery that eliminates the need for battery replacement, and ends worry of unauthorized battery removal. The alarm provides continuous protection from smoke and fire, even during power outages.
