Time Equipment Division in 1958. This purchase included IBM's fire protection division. Originally, Simplex's fire alarm line simply consisted of relabeled IBM devices and control panels, but they began to introduce redesigned IBM products starting in the early 1960s. In the mid-1960s, Simplex attempted to introduce low-voltage DC systems; these panels were not a success. Most of Simplex's audible notification appliances prior to the 1990s were relabeled Benjamin Electric, Federal Signal, Faraday, and Autocall devices. Simplex's time-division began to lose market share, but their newly founded fire alarm division significantly prospered. In 1970, Simplex introduced conventional control panels. In 1979, Simplex introduced the industry's first networked multiplex building control system that was capable of handling fire alarm, security, HVAC, synchronized time, and watchman's tour. Other products SimplexGrinnell also markets burglar alarms, PA systems, and nurse call systems. They also provide testing, inspection, and maintenance services for fire alarm, sprinkler, suppression, security, and communication equipment. To a much lesser degree, the company also sells and services pull stations, time clocks, and master time systems and Mass Notification systems.
