Inflexion is pleased to announce that it has made a majority investment in Detectortesters and System Distributors, Inc (“SDi”), which going forward will operate together as the leading global manufacturer of fire detector testing equipment.

Rick Heffernan, a long-term member of the SDi team who also sits on the board of directors of the Automatic Fire Alarm Association as its current President, will continue to lead SDi in the distribution of Detectortesters products across the Americas. The investment is being made by Inflexion Buyout Fund V.

Detectortesters established a joint venture with SDi in 2001 to oversee the North and South American sales and associated product support. Based in New Jersey, SDi operates a service centre providing re-calibration, maintenance, and repair services for fire detection testing equipment. Founded over 50 years ago, Detectortesters designs and produces solutions that enable testing of smoke, heat, and CO fire detectors. The company conducts all new product development in-house, working with all the major fire detector OEMs, fostering efficiency as well as proprietary innovation.

Inflexion will support the global management team at Detectortesters and SDi to continue product innovation, drive revenue growth through pricing strategies and sales channel optimisation, whilst accelerating international growth, particularly in the Americas region.

Rick Heffernan, President at SDi, commented “Detectortesters is currently a very successful, global business and have an exciting roadmap of next-generation testing equipment ahead. With the support of our new partner Inflexion, the SDi team are excited at the prospect of working closer with the Detectortesters team and the future growth opportunities available to us.”

Simon Turner, Managing Partner at Inflexion, commented, “The teams at SDi and Detectortesters have led their respective businesses to be the unequivocal leaders in high growth, regulatory driven markets benefiting from a high-quality offering and strong customer loyalty. The business is well positioned to grow further through geographic expansion and optimising their customer proposition. We look forward to working with this ambitious team.”
