💡 How do dual sensor smoke alarms actually improve home fire safety?

The upgrade works because tracking two different fire types cuts blind spots in older single sensor designs.

Here is why that setup saves lives when trouble strikes:

- Photoelectric lenses catch lingering charcoal clouds from overheated wires before gases spread

- Ionization metals track fast gas bursts from sudden gasoline or paper blowouts

- Cross checking both signals stops the alarm from tripping over burnt toast while still catching real threats early
