Deletion of Mobil Directo

Comment: I suggest a more thorough . There is a manufacturer article, American Signal Corporation, and there is an article on this product, ACA Allertor 125. Both of these currently lack sufficient sources, but these exist e.g.: https://books.google.co.uk/books?id=qpFEAQAAIAAJ (p167), https://books.google.co.uk/books?id=tktgGmLEX4UC (p206), https://www.newspapers.com/image/555220131/, https://journals.lib.unb.ca/index.php/mcr/article/view/20452/23613, https://www.vocativ.com/322401/tornados-noisy-warning-systems-and-their-super-fans/index.html etc
