Smoke alarms, or at least ionization-based alarms with a tiny amount of radioactive americium, are very simple devices. Inside the alarm, there’s a metal can – an ionization chamber – with ...

Google has discontinued its smart smoke alarm and partnered with First Alert on a new $129 detector that will work with ...

They can save your life, or go off when nothing's wrong. Here's what to do if your smoke alarm is giving you fits.

Through my testing, I found the Kidde smoke detector to be better performer for fast detection. It has both sensor types: ionization and photoelectric, which is why it was better able to ...

However, it requires a hardwired connection. All smoke detectors use one of two types of sensors to detect fires. Ionization-type sensors are best at detecting fast-burning fires, while ...

Ghana has been facing devastating fire outbreaks which sometimes lead to loss of lives, destruction of property and severe ...

It’s widely known that a smoke detector is a good ionizing radiation source, as they contain a small amount of americium-241, a side product of nuclear reactors. But what about other sources?

The response time of a smoke detector or fire alarm depends on factors such as the type of sensor, the fire's characteristics and environmental conditions. Ionization Smoke Detectors (detect fast ...
