The Allertor 125 is a rotating siren produced by Alerting Communicators of America. The Allertor is one of it's kind as it intakes air through the bottom horn, and blows it out the top horn, which had never been an engineering design up until that point. Another strange design was a chain driven rotator, which was proved to be extremely faulty. Even a simple rust or un-lubricated part of a chain rotator could snap out of place. Allertors were also extremely heavy, and had an unsupported pole mount, which made it very prone to falling over.
The siren came in 8/12, 9/12, and 10/12 port variations. The 8/12 and 10/12 versions are rare to find. The siren also came in a 8 port model, which is extremely rare.
The Allertor first became as a very strange idea brought up around 1945, ACA and many other civil defense companies were struggling to find reliable ways of allerting the public after WWII, as Russia had many threats to bomb and raid the United States. Around 1960, the first prototype of an Allertor was produced. Early models were made of metal. This slowly grew their popularity as it was cheap to make. In 1968, the Allertor was changed to the Allertor 125 when it's material was changed to fiberglass. Sadly, this change made the price increase dramatically, but nonetheless the siren was extremely popular. The Allertor lasted until 1980, where the P-10 would soon overcome the problems that the Allertor had, and would replace it.
