shues said:In modern fire apparatus the horn ring is not within reach of the officer's seat. If the officer is going to control the siren and the horns, foot switches are a must.
Also, if the engineer is going to control the siren and the horns, the horn ring can only be used for one of these functions. As such, using a foot switch on the left side for the air horns compliments the horn ring for siren control.
