What are smoke detectors? These are designed to sense smoke as a primary means of fire and immediately send out signals of warning about it. They detect fire particles or smoke with the help of photoelectric or ionization sensors. These sensors send signals to the alarm system, producing a loud voice and LED visible light as a warning. The goal purpose of smoke detectors is to alert people of smoke or fire particles and help them to vacate early and avoid inhaling hazardous smoke.
There are different types of smoke detectors or alarms. The question is, which are the best smoke alarms? Which smoke detectors are best and reliable? To answer these questions, it is best first to understand the three major categories of smoke detectors. They are categorized according to the type of sensors.
- Ionization Smoke Detectors : Ionization smoke detectors are made of radioactive materials that ionize the air creating a current. When smoke enters this detector, it creates a current that triggers and activates the alarm system. They are reliable and convenient to protect your family and property against fire. This is because they detect and sense even the tiniest and invisible fire particles. However, they have a drawback. Ionization detectors can be triggered by small and less serious smoke like a shower and food. They easily create a false alarm.
- Photoelectric Smoke Detectors : Photoelectric smoke detectors are designed with a smoking sensing chamber and source of light that is usually aimed far from the chamber. When smoke enters, it detracts light towards the smoke sensing chamber, which triggers the alarm system to send alert signals.
- Dual Smoke Detectors : These smoke detectors use photoelectric and ionization sensors to trigger the alarm system, hence the name dual.
