The Kidde PI9010 combines both ionization and photoelectric sensors in a single battery-powered unit, offering comprehensive detection for both fast-flaming and slow-smoldering fires. NFPA recommends having both sensor types in the home, and the PI9010 delivers both in one alarm. The Hush feature temporarily silences nuisance alarms without removing the battery. Easy to install with no wiring required. This model has been replaced by the Kidde 20SDR.
What is a dual-sensor smoke alarm?
A dual-sensor alarm like the PI9010 combines both ionization and photoelectric sensors in a single unit. The ionization sensor detects invisible particles from fast-flaming fires, while the photoelectric sensor detects visible smoke from slow-smoldering fires. NFPA recommends homes have both types, and a dual-sensor alarm fulfills this recommendation in one device.
Why is dual-sensor better than single-sensor?
Different types of fires produce different types of smoke. Ionization-only alarms may miss slow smoldering fires, while photoelectric-only alarms may be slower on fast flaming fires. A dual-sensor alarm provides broader protection by covering both scenarios.
Does the PI9010 need to be hardwired?
No. The PI9010 is fully battery-powered and requires no electrical wiring. It runs on a single 9V battery, making installation simple and suitable for any room.
How does the Hush feature work on the PI9010?
Press the Hush button to temporarily silence nuisance alarms from cooking or steam. The alarm will monitor air quality for a few minutes and reset if conditions return to normal. If real smoke is detected, the alarm will reactivate.
What replaced the PI9010?
The PI9010 has been replaced by the Kidde 20SDR, part of the DETECT line with advanced photoelectric sensing and reduced cooking false alarms.
