Pye-Barker Fire & Safety has acquired three companies from the Sonitrol Security Systems network. 

Pye-Barker closed in November on Sonitrol Security Services (dba Sonitrol of the Carolinas); Sonitrol of Charleston; and Sonitrol of the Midlands. Through these transactions, the Atlanta-based company gained four new locations, strengthening its market position as a single-source provider for integrated life-safety protection in North Carolina and South Carolina.
