🔥 What is a Fire Alarm System?
A fire alarm system is a network of devices that detect fire, smoke, or heat and trigger an alert through alarms and notification systems. These alarms help people evacuate safely and notify emergency services when a fire occurs.
A fire alarm system typically includes:
✔ Smoke & heat detectors – Detect signs of fire.
✔ Manual call points – Allow people to activate alarms manually.
✔ Alarm sounders & strobes – Alert occupants with loud sirens and flashing lights.
✔ Control panel – The brain of the system that processes signals from detectors and triggers alarms.

🔥 Types of Fire Alarm Systems
Different environments require different types of fire alarm systems. Here are the most common ones:
1️⃣ Conventional Fire Alarm System
✅ Divides a building into zones to identify the general location of a fire.
✅ Used in small to medium-sized buildings like offices, schools, and shops.
2️⃣ Addressable Fire Alarm System
✅ Assigns a unique address to each detector for pinpointing exact locations.
✅ Ideal for large buildings, hospitals, and commercial properties.
3️⃣ Wireless Fire Alarm System
✅ Uses radio signals instead of wiring, making installation easier.
✅ Great for heritage buildings, temporary sites, or hard-to-wire areas.
4️⃣ Aspirating Smoke Detection (ASD) System
✅ Continuously samples the air for early smoke detection.
✅ Ideal for high-risk environments like data centers and warehouses.
5️⃣ Hybrid Fire Alarm System
✅ Combines wired and wireless technology for flexibility.
✅ Used in large, complex buildings needing scalability.

🔥 How Does a Fire Alarm System Work?
A fire alarm system works by detecting smoke, heat, or flames and triggering an alarm. Here’s how:
1️⃣ Detection – Sensors pick up signs of fire (smoke, heat, or manual activation).
2️⃣ Signal Processing – The control panel analyzes signals from detectors.
3️⃣ Alarm Activation – If a fire is detected, alarms sound and strobe lights flash.
4️⃣ Emergency Response – Some systems automatically alert fire services.
