ATLANTA, GA — Pye-Barker Fire & Safety, on of the largest fully integrated and full-service fire protection, life safety and security services providers in the United States has acquired S.E.M. Security Systems, a security systems and fire alarm provider serving New Jersey and New York. This acquisition further establishes Pye-Barker’s security and fire alarm services in the Northeast, elevating customer experience and comprehensive fire and life safety for heightened community impact.
S.E.M. Security Systems provides security systems, intrusion detection, video surveillance, fire detection and fire alarm systems. Backed by 24-hour monitoring, S.E.M. Security installs, inspects, tests and maintains systems with an emphasis on safety and code-compliance. Based in Ramsey, New Jersey, and Warwick, New York, S.E.M. Security has over 35 years of experience in the security field with a stellar reputation for customer care.
What started as a career in fire protection expanded to the security sector when owner Stephen Mocarsky experienced a home break-in himself, sparking a new mission to protect others in his local community from similar incidents.
S.E.M. Security System’s skilled technicians will continue to serve customers in the Northeast. Nelson Mullins Riley & Scarborough, LLP represented Pye-Barker in the transaction.
“S.E.M.
