The Kidde PI2010 combines both photoelectric and ionization sensors in a hardwired interconnect alarm for comprehensive fire detection. The ionization sensor responds quickly to fast-flaming fires while the photoelectric sensor detects slow-smoldering fires — together providing the broadest possible coverage. It can function standalone or as part of an interconnected hardwired system. The Hush feature temporarily silences nuisance alarms. This model has been replaced by the Kidde 20SAR.
Why choose a dual-sensor hardwired alarm?
The PI2010 combines both ionization and photoelectric sensors, covering the two most common types of residential fires. Ionization detects fast-flaming fires, and photoelectric detects slow-smoldering fires. NFPA recommends having both types in every home.
Does the PI2010 support hardwired interconnect?
Yes. The PI2010 supports hardwired interconnect with up to 24 compatible Kidde devices. When any alarm in the chain detects smoke, all interconnected alarms sound simultaneously.
Can the PI2010 operate without being interconnected?
Yes. The PI2010 can function as a completely standalone alarm. Connect it to the 120V AC supply and it operates independently without any interconnect wiring to other units.
What is the battery backup on the PI2010?
The PI2010 includes a 9V battery backup that maintains alarm operation during power outages. Replace the battery annually or when the low battery chirp sounds.
What model replaced the PI2010?
The PI2010 has been replaced by the Kidde 20SAR DETECT-line model with enhanced photoelectric sensing and improved interconnect, or for true dual-sensor coverage, consider the current Kidde dual-sensor hardwired options.
