About ATW

ATW Security, a division of Mascon, Inc., started in 1987 in the security industry with a small peripheral product line. Initially, the company operated under Alarm Technology Worldwide, and then in 1999 became ATW Security. Based out of Woburn, Massachusetts we offer a full line of sirens, speakers, piezos, CCTV mounts, strobes, and accessories for residential and commercial systems. This includes our best-seller from the Watchdog Collection, The Doberman, and our best-selling piezos, PC-200, and PC-300. We have grown through the years starting with a standard line of quality products and more recently adding to our line with products unique to ATW. We continue to grow with each new year.
