The difference between smoke and heat detectorsMayara
Two of the most important pieces of a commercial fire alarm system are the heat and smoke detectors. These two devices alert your entire fire alarm system when a fire erupts. If you’re unsure of what exactly these devices do, don’t worry—it’s very simple. In fact, the difference between smoke and heat detectors is right there in each name. Smoke detectors will alert your system if it detects smoke. Heat detectors will instead alert your system when it detects high temperatures.
Although the difference between smoke and heat detectors lies in how they detect hazards, each device uses a few different methods to do so. For instance, there are two types of heat detectors: fixed-temperature and rate-of-rise.
Fixed-temperature detectors monitor excessive heat with the help of eutectic alloys, which are found inside of the device. When this substance melts in the presence of excessive heat, it notifies the alarm system. Rate-of-rise heat detectors, on the other hand, notify the alarm system when they detect a rapid spike in temperature.
Just as there are two types of heat detectors, there are also two types of smoke detectors: ionization and photoelectric. Ionization smoke detectors have a flow of ions inside made possible with the help of two electrically charged plates and a small amount of radioactive material. When smoke enters the chamber, it disrupts that ion flow, prompting the device to alert the fire alarm system. Photoelectric smoke alarms have a small light sensor inside of them instead of the plates and radioactive material. When smoke enters and blocks the light, it will trigger the alarm system as well.
Being familiar with your commercial fire alarm system is important if you want it to function properly. These devices require maintenance throughout the year in order to detect dangers in the environment, so it’s good to know about them inside and out.
