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 ...

These employ both technologies — ionization and photoelectric — in one device. All three types of smoke alarms come in battery, hard-wired and smart versions. Each offers different advantages.

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 ...

Generally, there are two primary types of smoke detectors: an ionization smoke detector and a photoelectric smoke detector. The International Fire Chiefs Association recommends having at least one ...
