ATLANTA — Full-service fire protection, life safety and service service provider Pye-Barker Fire & Safety has acquired San Antonio, Texas-based Communication Systems International dba CSI, enabling Pye-Barker to “bring full-service code compliance and peace of mind to more customers throughout Texas.”
Established in 1996, CSI is a fully integrated and diversified security and communications company led by co-owners Carl Lyssy, Roger Lyssy and Darryl Mosses.
The company designs, installs, tests and maintains fire alarm and security systems. It also “specializes in video surveillance and monitoring, access control and communication systems, integrating products into a single solution that meets customer needs and provides peace of mind for commercial, industrial and residential buildings,” according to the joint announcement.
Why Did Pye-Barker Fire & Safety Acquire CSI?
“Selling this company required the perfect culture match and Pye-Barker provides just that,” says Carl Lyssy, co-owner of CSI, in the joint announcement. “It’s a relief to know we are now a part of a company with the national impact and resources needed to back our local mission. Together, we can continue to push innovation in fire and life safety to protect the communities we live in.”
“The integration of CSI into our team presents an exciting opportunity,” says Bart Proctor, CEO of Pye-Barker, in the announcement. “The addition not only adds to the capabilities of our comprehensive services in the San Antonio market, but most importantly this helps us protect more buildings, more people and more communities from the devastating impact of fire and life safety threats.”
CSI’s team and technicians will continue to serve customers in Texas.
Nelson Mullins Riley & Scarborough, LLP represented Pye-Barker in the transaction. CSI was represented by the Law Offices of Marc P. Katz, LLC and Tim Shiner with Sell Alarm Company.
