Autocall was a Shelby, OH company that specialized in fire protection and customized communications equipment. The company went defunct in 2001 after it was incorporated into the SimplexGrinnell merger by Tyco International.
Early History
Autocall was founded in 1908 by two businessmen from Shelby Electric Company after they witnessed a demonstration of a unique telegraph system in use at a plant for employee communication while on a business trip. Seeing the need for such a system at their own company, the two designed an automatic version of this system and founded Autocall. Soon after, the company produced their first 120VAC coded fire alarm system. In 1920, an advertisement centered on the infamous Triangle Shirtwaist Factory Fire helped to gain the company significant business and began to establish them as a serious competitor in the industry. In 1922, the company created an automatic punch recorder designed to record system status changes by punching holes in ticker tape. In 1933, Autocall purchased the Howe Manufacturing Company of Chicago, IL and used their proprietary transmitter design to produce the Autocall-Howe system, a high-end fire alarm system targeted at large institutions and industrial plants. By the 1960s, Autocall-Howe systems were installed in many of the United States' largest factories, airports, and universities.[1]
Innovations
Starting in the mid-1960s, Autocall began transitioning all of their fire alarm systems to solid state technology. In 1970, the company produced the NA series of fire alarm systems which utilized modular components driven by printed circuit boards instead of traditional hardwired relays. In 1973, Autocall invented the first voice evacuation system, followed by a firefighter's communication system in 1974. These technologies were OEM distributed to numerous other fire alarm companies who did not yet produce their own. In 1977, Autocall introduced Auto Monitor, an entirely solid-state multiplex system that utilized remote transponders to distribute IDC's and other connections. These transponders could handle up to 8 points and remained in production for several years thereafter. A year later, the company introduced the Auto Command, a remote microprocessor-controlled command center with built-in printer. The Auto Monitor interpreted network command centers as transponders on the multiplex loop. Shortly thereafter, the company introduced custom designed rackmount systems which had to be factory programmed for each client. Due to the rapidly growing clientele and increased complexity of programs, Autocall brought field programmability to its multiplex systems in the mid-1980s. In 1987, Autocall introduced a smaller series of one-loop field-programmable addressable systems for a burgeoning market of mid-size addressable applications. In 1989, Autocall introduced the first color touchscreen graphic annunciator, known as Autograph. In 1990, the company replaced the aging Auto Command II system with the AL-1500, a modern system capable of over 4,000 points.[2]
Demise
In 1990, the company was bought by Wormald International which then sold the company to Thorn Security. Under the name "Thorn/Autocall", the company produced the TFX-series addressable panels and C-series conventional panels. When Thorn was purchased by Tyco-owned Grinnell in 1996, their systems were branded under "Grinnell/Autocall".[3] In 2001, Tyco purchased Simplex Time Recorder Company and merged it with Grinnell, forming SimplexGrinnell. The entire line of Autocall products was subsequently discontinued, though SimplexGrinnell kept their factory open for production of replacement parts. SimplexGrinnell still supports legacy Autocall products and offers a 4100ES upgrade kit for TFX-series systems.[4]
