2. Types of Fire Detection Systems
A. Domestic Smoke Detectors
| Type | Best For | Pros | Cons |
|---|---|---|---|
| Ionization Alarms | Fast-flaming fires (paper, grease) | Quick response to flames | More prone to false alarms near kitchens |
| Optical Alarms | Smouldering fires (furniture, wiring) | Better at detecting slow burns | Slower for flaming fires |
| Heat Alarms | Kitchens, garages | No false alarms from steam/smoke | Only detects temperature changes |
| Combined Alarms | All-round protection | Smoke, heat & CO detection in one | Higher cost |
B. Commercial Fire Alarm Systems
| Type | Best For | Key Features |
|---|---|---|
| Conventional Systems | Small offices, shops | Basic zoning (2-8 zones) |
| Addressable Systems | Large buildings (schools, hospitals) | Exact location identification, advanced diagnostics |
| Wireless Systems | Heritage buildings, temporary sites | No cabling needed, flexible installation |
| Aspirating Smoke Detection (ASD) | Data centres, clean rooms | Ultra-early warning, high sensitivity |
