Have you ever had to break one of those alarm panels which are labeled “In the event of an emergency, break glass”?

Even those which are made of thin plexiglass and etched so as to crack especially easily make people think twice before activating them. In an emergency, that delay of even a few seconds, whilst one considers how to do the breaking and what damage your hand may sustain in the process, can be significant.

Today’s invention is therefore a reuse of the ring-pull can top, such as can be found on eg a tin full of chopped tomatoes. Instead of breaking any glass, the familiar ringpull would allow a metal disc to be easily removed, exposing an alarm button (or even using the broken seal itself as an electrical alarm switch).

People would be much more willing to pull the ring than smash a panel into fragments.

  1. Oooops. I just remembered I’d seen this somewhere before https://iotd.patrickandrews.com/2009/02/23/801-panican/
    Interesting I had no recollection of this, nor of the fact that I’d even used the name before.
