Fire Detection System
In short
A building-wide network of sensors and alarms designed to identify fire, smoke, or gas and alert people to evacuate.
In plain words
It uses special tools like smoke or heat sensors to spot danger early. When a sensor trips, it sends a signal to a central panel which then rings loud bells or sirens to warn everyone inside.
A simple example
In an office, a smoke detector in the ceiling senses fumes from a small electrical fire. It immediately triggers a loud siren and sends a signal to the local fire brigade.
Why it matters
These systems save lives by providing early warnings before a fire becomes uncontrollable. They also help emergency services arrive faster by alerting them automatically.
Easy to mix up
Do not confuse this with a fire suppression system, which is designed to put the fire out rather than just warning people.
