You have to test it frequently, the reason is that smoke may be visible or may be not and you want to see all particles that emanate from any kind of smoke, specially during night time when you are asleep. Most of dust/ash particles may not be visible and via ionizing detector they will be!!!! Alarm will go off making alert sound and you will be safe.
So, sumirizing, you need to test ionizing smoke detector to see if sensor is in ok condition.

What is ROR in smoke detector?
really old rapter
What happens if your smoke detectors goes off but there's no smoke?
This may because specs of dust can cause activation of the detector as it has the same effect as smoke. Spiders also can crawl into the sensors which does the same thing- same way with deodrant, paintfumes etc. It also may be because the smoke detector is just faulty.
How would one make a lock that is triggered by a smoke detector?
Perhaps a two-stage process. Firstly, gain access to the electrical output in the smoke detector, that drives the noise transducer. Use this (amplified?) to drive the mechanism of your electrically-operated lock.
What is an elevator shunt trip test?
An elevator shunt trip test checks the heat detector placement. It also monitors power and wiring diagram of an elevator.
Guide to install fire smoke detector above false ceiling?
I don't believe that if you place a smoke detector inside a closed space like above a false ceiling , it will have the same effect than if it was attached to the ceiling on the occupied space side. See the related link for some general guidelines and always check local codes or with the fire marshall for specifics.
What does americium do in smoke detectors?
Yes, americium is used as ionizing source in smoke detectors.
Why the Americium is used in smoke detectors?
In the smoke detector, the fast - moving alpha particles enable the air to conduct an electric current. As long as the electric current is flowing, the smoke detector is silent. The alarm is triggered when the flow of electric current is interrupted by smoke entering the detector.
Many smoke detectors contain?
a. Americium-241 Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.
Why the smoke alarm beeps when you take a shower?
Some smoke detectors use ionizing radiation to sense smoke and it can become confused with water vapor (steam), which is why ionizing smoke detectors are not allowed anywhere near sources of steam. Try replacing it with a photo-electric detector and make sure it's outside of the immediate area of the shower (i.e., in the bedroom or out in the hallway).
Where is the test button for the smoke detector?
It is a green button on the front of the outside case.
Can you hook a smoke detector up to a switch to make it sound?
Sure, but what you would have to do would be to put the switch in the TEST circuit of the detector.
Explain why americium-241 would be an ideal isotope to use in a smoke detector?
Alpha particles from americium ionized the air. An air with smoke has a different ionization, ionization currents which are also different are measured, compared and the detector (which is before calibrated) is ready !
How often should smoke detector batteries be changed?
When the smoke detector first starts signaling low battery with short widely spaced high pitched chirps, or if when you press the test button the alarm does not trigger.After replacing the batteries, press the test button. If the alarm does not trigger with fresh batteries, replace the smoke detector.
Smoke detectors are they safe for us?
Yes, even though they do emit ionizing radiation. The amount of radiation emitted from a smoke detector is about 1 hundredth of a millirem per year. The background radiation from radioactive isotopes in the ground is about 300 millirem per year. So the ground your standing on right now is exposing you to more radiation then your smoke detector ever will.
Can you buy smoke detector tape?
Personally, I have no idea what "smoke detector tape" is.
Was the smoke detector proposed for a mission?
actually no, the smoke detector was not proposed for a mission
How can a smoke detector be tested to see if it is working properly?
To check and make sure your smoke detector is working you can test them or check and see if there a green light meaning they are working. Its better to test them. If you have had a power outage recently they could be dying.
