At 15, he was building alarms and knew he wanted his own alarm company. Linder formed American Fire Dispatch (AFD) with his two partners just a few years later. They sold AFD to Baker Industries, which later became Wells Fargo Alarm Services. After leaving Wells Fargo, Linder started two other California alarm companies: General Protection Services, which he sold after a short time, and ElectroSecurity, which was sold last year to Bay Alarm Co.
Linderâ€™s ideas revolutionized the alarm industry in southern California: plug-in transformers; Gamewell six-circuit recorders; the West Coastâ€™s first computerized central station; and McCulloh fire alarm transmitters. In addition to being an innovator, friends agree that Linder was always willing to help and share knowledge. â€œHe would put his work on hold to help somebody else,â€ said his wife, Faye Linder.
â€œHe was never reticent about telling people what he was doing,â€ said friend Frank Meiners, adding that his career in the alarm industry was dependent on Linder. â€œYou might say he started many, many careers as a result of his nurturing.â€
In 1967, Linder and other entrepreneurs started Western Burglar and Fire Alarm Association. He became the first president. He was a long-time member of the board of directors of the Los Angeles Burglar and Fire Alarm Association, as well as its successor, the Southern California Security Association. â€œHe was just security all the way,â€ said Faye Linder. â€œEmployees liked him, not only as a boss, but as a person.â€
