The Chirp Registry: a field guide to ceiling-mounted birds
A comic smoke-alarm field guide pairs fictional alarm “species” with an interactive low-battery chirp simulator and practical maintenance advice.
- For
- People trying to identify a smoke-alarm chirp
- Worth noticing
- The seven alarm “species” are fictional; the browser-synthesized sound is described as roughly 3.2 kHz.
Field notes
The simulator plays a browser-synthesized piezo-like tone at roughly 3.2 kHz, with the low-battery chirp recurring at a randomized 20–70-second interval. A separate specimen section lists seven fictional alarm “species,” their calls, and battery-changing rituals; audio starts only after the visitor presses play. The practical section recommends monthly test-button checks and alarm replacement about every 10 years, and notes Victoria-specific landlord responsibility for renters.
