Smoke Detector Types:

Fire happens every day. In 2014, firefighters alarm once every 24 seconds. If you have a smoke detector at home, you will have a better chance of keeping everyone safe. Although any smoke detector is always better than nothing, there are many models to choose from, with a variety of advantages and disadvantages:

MultifunctionSome smoke alarms do more than just detect fire. Many also include carbon monoxide detection – providing double protection in one device. Multifunction alarms can be battery powered, wired or smart, so the price is not the same.

CleverSmart Smoke Detectors lead the way in fire safety. They communicate through the application and send alerts when an alarm goes on. Smart alarms can also talk to each other, so if the alarm is triggered, you know exactly where the fire occurred. The only downside is that smart devices are more expensive, but you can get a lot of security in order to reduce costs.

Battery poweredBattery-powered smoke alarms can not be connected to the electrical system in your home. Instead, they run on battery power. Benefits – They do not require complicated installation. Smoke Detectors only hiccup is that if the battery is dead, they lose their activity. Since dead batteries caused approximately 25% of smoke detector failures in 2014, this is a potential risk you should be aware of.

There are smart batteries on the market that can communicate with your phone in low battery conditions.3 If you are using a battery-operated smoke alarm, consider using this battery.

Hard lineHard-wired smoke detectors have wires that connect to the home electrical system. Smoke Detectors have a spare battery to prevent the device from being used. Hard-wired smoke detectors are a very reliable option because of the low probability of losing power. Although, they need more installation knowledge.

Smoke Detector Sensors Working:

Smoke detectors typically have three types of sensors: ionization, photoelectric and dual. Here are the main differences between the three:

Photoelectric sensorsOptoelectronic sensors can better detect smoldering fires that generate a lot of smoke. These sensors use a light to detect smoke and trigger an alarm.

IonisationIonization sensors are designed to detect quickly burning, flaming fires due to the small amount of smoke they produce. They are equipped with two metal plates and a small amount of radioactive material to ionize air. When smoke flows through the unit, it stops the ionization and triggers the alarm.

Two sensorsDouble sensors include both photoelectric and ionization sensors. They are considered to be the safest smoke detectors as they detect both smoldering and blazing fires.
