With a broad range of choices, it is unthinkable why certain homes give this device little importance. Let us take a sweeping review of the different types of fire alarm systems.


Automatic alarm systems are designed to detect unwanted presence of fire, or anything that denotes its presence such as heat, smoke, or carbon monoxide. It is also designed to notify the building or home occupants for prompt action or evacuation in such event as well as to control its spread.

2. Thermal fire alarms are sensitive to heat using a sensor. When the sensor is heated, there will be a change in conductivity that triggers the alarm.

3. Ionization fire alarms detect the smoke that emanates from the fire. It uses a radioactive material. With contact with the smoke, conductivity ions are created that completes the electricity circuit that sets off the alarm.

4. Manual alarms require the pulling of a handle to sound off the alarm. These are mounted on walls of buildings for whoever sees fire or billows of smoke that signifies fire.

5. Interconnected Fire Alarms are usually found in big buildings. Once one alarm goes off, they all go off one after the other to warn building occupants about the pending dangers of a fire or emergency.
