Before heading out to find a replacement fire alarm system for your home or business, you must first determine which type you own. Many of the models look similar, but they are not all one in the same. Below is a comprehensive guide to the main types of fire alarms on the market and their notable characteristics.

3 Types of Fire Alarms

1. Ionization Detector

Ionization smoke alarms use a small amount of radioactive material between electrically charged plates to ionize air around the detector. If smoke particles enter the ionized air, this will set off the alarm. This type of detector is one of the most commonly used today because it quickly detects fast-moving fires. 

2. Photoelectric

Photoelectric detectors use a light sensor to detect smoke patterns. They are the most effective with smoldering, slow-burning fires and have become popular because they bypass issues where an alarm is set off by steam from using the oven or stove.

3. Dual-Sensor

Dual-sensor alarms are designed to use both ionization and photoelectric sensors. This is to capitalize on the safety benefits of each alarm system without having to purchase two separate models. Some alarms require both sensors to be set off before the alarm sounds to reduce the frequency of false warnings.
