Ben Mincey and the Red Hots responded to big fires all over the city, but their primary responsibility was for East Wilson. The 1922 Sanborn fire insurance map shows all the fire alarms  set up thoroughout the district.

Note the clusters in sections 17, 26, and 28 on the sites of industrial complexes. Also note the relative rarity of alarms on residential streets east of the tracks. If a house caught fire on, say, the corner of Carolina and Reid, some hard running was required to raise the alarm.

A close-up showing the alarm, marked F.A., at the junction of East Green and Elba Streets.
