Tyco International (NYSE: TYC) announced today that its ADT North America Commercial Security business unit, the industry’s leading security systems integrator, is changing its name to Tyco Integrated Security. The new name will be phased into use over the coming months.

“Commercial enterprises have different, more complex needs from homes and small businesses, and this name change, from ADT North America Commercial Security to Tyco Integrated Security, is representative of our continued focus and commitment to the commercial market,” said Brian McDonald, COO, Tyco Fire & Security. “We’re building on more than 100 years of experience in the commercial security industry, and investing in the future to continue to deliver the most efficient and innovative security solutions to businesses.”
