Worry-Free Combination Smoke & Carbon Monoxide Alarm with Sealed Lithium Battery Power

P3010CU

The Kidde P3010CU is a 10-year, sealed battery, smoke and carbon monoxide alarm with a voice warning system that features photoelectric and electrochemical sensing technology with Smart Hush feature. This combination alarm combines the detection capabilities of a photoelectric sensor with that of an electrochemical sensor, which is used to detect CO. When either sensor notices a potential hazard, it will communicate with the other.

  • Voice Alarm: Announces the hazard type detected.

  • Test/Hush Button A single button that tests alarm circuitry and temporarily silences nuisance alarms.

  • LED Indicator: A flashing red indicator blinks to correspond with alarm sound, unit error mode, and standby condition.

  • Combined Smoke and Carbon Monoxide Alarm: Unique sensor algorithm detects real fires faster and reduces nuisance alarms.
