How to select the best fire alarm for your home?

Generally speaking there are two types of fire alarms which are in use. These two types of fire alarms are as follows:

  • Ionization alarm: In this type of alarm, americium 24 is used which is a radioactive element. It is used in this type of alarm to ionize the air inside the alarm. Thus, it creates an electrical circuit inside the alarm. Hence, when the smoke enters inside the alarm it breaks the circuit made by the radioactive element and sets the alarm to ring thus alerting the occupants of the house regarding fire.
  • Photo electric alarm: This is the type of fire alarm which uses the light to detect the fire. In this fire system, a source of light is being sourced in the sensing chamber. The angle of the source of light is being kept away from the sensor. When the smoke enters the chamber it reflects the light on the sensor thus triggering the fire alarm.
