The Kidde PI9000 Dual Sensor Smoke Alarm uses photoelectric and ionization sensing technologies which creates a broader detection against smoke from open flame or smouldering fire situations.
Many experts say that you should have an alarm that uses both these technologies in your home as it provides an increased protection against different fire scenarios.
The Kidde PI9000 smoke alarm has a great “Hush” feature which allows you to quickly silence any false alarms.
The PI9000 allows you to easily check the battery status with an obvious but sleek button and LED indicator.
The advantage of the photoelectric smoke sensor is that it can detect larger, smouldering and visible fires caused commonly by smouldering materials such as cigarettes a lot quicker than the ionization sensor. However, the ionization sensor can detect smaller fire particles from flaming fires caused by such things as flammable liquids faster than the photoelectric sensor.
This is why the Kidde PI9000 is the fire alarm of choice among many experts. Here are some helpful specs on the PI9000:
All in all this is a great alarm. I have been using it for years with no failures or false alarms. The alarm is very loud comparing to other similar alarms. This is the reason I would especially recommend the Kidde IP9000 to deep sleepers and elderly people.
