Fire / smoke alarm kit
Safety sensing
Golden rule: Explore for inspiration. Log in for progress. Purchase when you’re ready to commit.
No account needed to imagine your build
Scroll the catalog, open any path, and picture the outcome. Try a demo or workshop if you want more spark. Log in when you want checkpoints and saved progress. Buy the kit only when you’re committing to the build.
Sensor trips → buzzer/LED alarm. Keep it low-voltage and educational — not a certified life-safety product.
