What does a fire Alarm work

Question

Accepted Answer

A fire alarm is a system that detects and alerts people to the presence of fire, allowing for timely evacuation and fire suppression.

Fire alarms work by detecting smoke, heat, or flames through sensors.
When the sensors detect a potential fire, they send a signal to the control panel.
The control panel then activates the alarm devices, such as sirens, strobe lights, and voice evacuation systems.
Fire alarms can also be connected to a monitoring service that alerts emergency responders.
Regular maintenance and testing are essential to ensure the proper functioning of fire alarms.

Accepted Answer

How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.
