Santa Ana’s Allied Universal, the nation’s largest private security force, said it will acquire Securadyne Systems, a Dallas based provider of security systems.

After the acquisition is completed April 15, Securadyne Systems will become the technology service platform upon which Allied Universal will build its global systems integration capabilities, the company said in a statement.

Allied Universal said it will become the fourth largest security systems integrator in the U.S.

“Our new acquisition of Securadyne Systems supports our long-term strategy to become the leader in the security technology market,” Allied Universal Chief Executive Steve Jones said.

Terms of the deal were not disclosed. Founded by CEO Carey Boethel in 2011 in partnership with Pamlico Capital, Securadyne Systems offers security consulting, design, engineering and installation.

With revenues in excess of $73 million and more than 300 employees, Securadyne has a branch network of more than 17 locations across the United States.

Advisers to Allied Universal for this transaction included Ernst & Young (EY) and Sheppard Mullin.

Allied Universal was valued at more than $7 billion in February after an investment from a Canadian pension fund.
