According to publisher notes, The ADT Transmitter was, “A monthly news-magazine of outstanding events and features concerning fire, burglary and holdup…. Edited and distributed for the information of employees, subscribers and other interested persons.” The ADT Transmitter was published monthly from 1929 to 1970.

All issues of The ADT Transmitter are 8 pages in length and printed on standard 8-1/2 x 11 inch paper. Layout is 3 columns per page, with pictures interspersed throughout each issue.

The ADT Transmitter was printed in two slightly different formats. The early issues from 1929 to 1936 were newsletter-like in format and printed in a single color (black).

Beginning in 1937 the format changed. Issues from 1937 to 1970 were formatted more like a magazine, with a three color (red, black and white) title across the upper two inches of the front page. A photo filled the remainder of the cover page. The remaining pages were single color (black).

Two issues of each format are available for viewing and/or download:
