For most standard homes, smoke alarms are recommended on each floor, specifically in hallways and on landings. It's also wise to place them in other rooms where a fire might start, except for kitchens. In kitchens, cooking fumes can trigger smoke alarms; instead, a heat alarm is a better choice as it detects sudden temperature increases from a fire. While this setup is usually sufficient for most homes, larger or luxury properties might benefit from a full fire alarm system for enhanced peace of mind.
