What does it mean when a smoke detector has the letter I?
2. Dust on the Sensors. If the smoke detector has the letter “I” in its model number, or if it mentions radioactive material on the back of the smoke detector, then it’s an ionization smoke detector. It’s possible for an ionization smoke detector to mistake dust for smoke.
Why is it important to have a smoke alarm?
Smoke alarms help save thousands of lives every year. A working fire alarm is crucial to the safety of your home. While it is possible for a smoke alarm to give so many false alarms that we’re sometimes tempted to remove the batteries, it’s important that we don’t. Smoke in a home can be a life or death situation.
What detectors detect smoke?

If you notice dust, cobwebs, or other “stuff” on the offending smoke detector, use canned air or a vacuum attachment to clean it out. Fair warning: Moving all that debris around can cause the alarm to sound again.
Can ionization detectors detect fires?
Old-school ionization detectors are great at sensing fast fires with lots of flames. They often don’t catch the slow-burning, smoldering fires that create loads of smoke, though. Since smoke inhalation is the number-one cause of death related to fires, we strongly recommend not relying solely on ionization detectors.
Can a dual smoke alarm be used for a smoldering fire?
This type of smoke alarm is great at catching smoldering fires without much flame. Dual alarms have both types of sensors. Depending on the unit, one or both sensors need to be triggered for the alarm to sound. The NFPA recommends using both types of alarms.

What are the different types of smoke detectors?
But actually, there are two types of smoke detectors, which include photoelectric and ionization. Because they both specialize in different types of smoke detection, there is no way to know which type of detector is best for you.
How to fix a smoke detector that is not labeled?
A loose wire can also cause this problem. To fix this, go to the breaker box and turn off the breaker to the smoke detectors. If you do not see one labeled for the detectors, turn it off at the main breaker. Wait a few minutes and switch it back to the on position. This should fix the problem.
