Meet the Vulcan Autosonic — a mechanical, wind-up fire alarm from 1971.
Terrible alarm system.
Here’s why smoke detectors replaced these:
🔥 Most fire deaths come from smoke inhalation, not flames
🔥 Smoke fills a room way before the ceiling hits 135°F
🔥 A modern smoke alarm gives you escape time.
A heat alarm, such as this, gives you a warning that the house is already on fire.
Add in the fact that this thing has no self-test, no battery backup, and a 50+ year old spring mechanism that may or may not still work… and you’ve got a device that belongs in an antique store, not a ceiling.
