Here’s a link to my collection on my website: http://kcin556alarmwebsite.weebly.com/collection.html
Be warned, the pages are photo heavy, but pictures for individual alarms are arranged in slideshows so they load pretty quickly. There’s also a link on the main collection page somewhere to pictures of industrial signs I collect, if anyone’s interested.
Nice collection! I would die for such a vast and rare of a set. I do like the decibel feature you added in. Very interesting.
