HE City of Memphis was not content to call


its Municipal Buildings adequately pro


tected without the ever-watchful electrical fingers and eyes of A. D. T. Central Station Service.
The Shelby County Court House, containing the administrative offices of the City of Memphis as well as the
county, is equipped with A. D. T. Watchman s Compulsory
Tour, Emergency Alarm Box, Burglar Alarm, and Police Call


Services. The City Treasury is protected day and night against holdups and burglaries.




The Department of Parks, Prisons, Streets, Sanitation


and the Public Library use A. D. T. Protection Services in various forms.
A. D. T. has been specified by leading architects for the newest, biggest and best buildings of all kinds. It protects
more than aa billion dollars worth of property and has been
a Symbol of Security since 1873.
