Siemens Building Technologies Inc., Buffalo Grove, Ill., announced the acquisition of MAC Systems Inc., Canton, Mass.

MAC Systems, a New England security systems integrator, has been installing and maintaining access control and security management systems in the region since 1981.

MAC Systems Inc. ranked No. 42 and Siemens Building Technologies Inc. ranked No. 1 on SDM’s Top Systems Integrators Report in 2008.

“MAC Systems is one of New England’s leading security systems integrators,” said George West, vice president and head of Siemens Building Technologies Security Solutions business unit. “Our customers throughout New England will benefit from the combined resources and experience of our two companies.”

The acquisition, which strengthens Siemens ability to serve current and prospective customers in the region, will integrate MAC Systems operations and its approximately 60 employees with its network of branch offices located throughout the New England states.

In the near term, plans call for MAC Systems to operate from its current location as a branch office of Siemens Building Technologies Inc.

“Our new status ensures that our customers will continue to have access to the highest levels of service, technology and integration experience,” said Robert McMenimon, who founded MAC Systems.

“We are truly excited to be a part of Siemens. It is a great fit – we are now a part of one of the most trusted names in the security industry and I am confident our employees will thrive in an organization that, like MAC Systems, is driven to develop and implement innovative solutions that confront the most urgent challenges of security.”
