Cheap and effective when maintained properly.
Smoke detectors will run out of battery over time as they are not wired in to the houses electrical system.
Statistics show that far fewer people die in house fires when smoke alarms are present.
When the smoke alarms are placed to close to bathrooms steam may interfere with the detector, triggering false alarms.
Ionization detectors seem to respond better with high flames which could be a problem under certain circumstances.
14-3 Is the standard wire use for residental smoke detectors.
The smoke spreads very far.
Electrical equipment should be tested every 6 months like your smoke detectors and your furnace . Electrical fires are the 3rd leading cause of fires in Canada, so test ,test test.
The codes are local and may be different in each jurisdiction. Check with the local fire inspector. At any rate I recommend both, especially if you have a gas fired heating stove or fireplace for the CO2 detector. I have combined detectors everywhere. The other question is if local code requires a hard wired detector with battery backup.

Photoelectric smoke detectors use a light beam to detect smoke particles, while ionization smoke detectors use radioactive particles to detect smoke. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-flaming fires.
Ionization smoke detectors use a small amount of radioactive material to ionize the air, while photoelectric smoke detectors use a light beam to detect smoke particles. Ionization detectors are better at detecting fast-flaming fires, while photoelectric detectors are more sensitive to slow-smoldering fires.
The main difference between a photoelectric smoke detector and an ionization smoke detector is the way they detect smoke. Photoelectric detectors use a light beam to detect smoke particles, while ionization detectors use radioactive particles to detect smoke. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-burning fires.
Photoelectric smoke detectors use a light beam to detect smoke particles, while ionization smoke detectors use radioactive particles. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-flaming fires. Overall, photoelectric detectors are considered more effective in detecting smoke particles.
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 was before calibrated) is ready ! The americium smoke detectors (with ionization) are not the first smoke detectors.
Ionization smoke detectors use a small amount of radioactive material to ionize the air, while photoelectric smoke detectors use a light beam to detect smoke particles. Both technologies are effective in detecting smoke and fire, but photoelectric detectors are generally more effective at detecting smoldering fires, while ionization detectors are better at detecting fast-flaming fires. It is recommended to have both types of detectors in your home for maximum safety.
There are two smoke-sensing technologies commonly used in residential smoke detectors: photoelectric and ionization
Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
The smoke detectors use the photoelectric effect or a sensor based on the ionization differences between smoke and air.
There are two smoke-sensing technologies commonly used in residential smoke detectors: photoelectric and ionization
An ionization smoke detector is a type of smoke alarm that uses a small amount of radioactive material to ionize the air inside the detector. When smoke particles enter the detector, they disrupt the ionization process, triggering the alarm. This type of smoke detector is more sensitive to fast-burning, flaming fires, but less sensitive to slow, smoldering fires. In comparison, photoelectric smoke detectors use a light beam to detect smoke particles, making them better at detecting slow, smoldering fires. Dual-sensor smoke detectors combine both ionization and photoelectric technologies for more comprehensive fire detection.
Ionization smoke detectors are effective at quickly detecting fast-burning fires and are generally more affordable than other types of smoke detectors. They are also less prone to false alarms from cooking smoke or steam, making them a reliable choice for home or office settings.
