| Criteria | Ionization Detector | Photoelectric Detector |
|---|---|---|
| Pros | - Quick response to fast-flaming fires. - Affordable and widely available. - Lightweight and compact. | - Quick detection of smoldering fires (e.g., from furniture). - Fewer false alarms from cooking smoke. - Better performance in homes with interconnected alarms. |
| Cons | - Prone to false alarms near kitchens or bathrooms. - Less effective for smoldering fires. - May require frequent cleaning to avoid dust buildup. | - Generally more expensive than ionization models. - Slower to detect fast-flaming fires. - Larger in size due to more complex components. |
| Ideal Use Case | Near bedrooms, hallways, and areas away from cooking smoke. | Near kitchens, living rooms, and areas prone to slow-smoldering fires. |
| Price Range | $180 - $200 | $200 - $220 |
