A fire alarm is a crucial safety device designed to detect and warn people about the presence of fire in a building.

Its primary purpose is to provide an early warning, allowing occupants to evacuate safely and take appropriate actions to control the fire or seek help.
When a fire is detected, the fire alarm system activates all the necessary alarms simultaneously, alerting the occupants to evacuate immediately and take predetermined escape routes.
