Field Programming
CHAPTER 2
The FIRE•COMMAND•25/50 VECP can be field programmed using option DIP switches S1 and S5 located in the
upper right side of the main circuit board. It is recommended that tone selection, message repeat cycles and back-
ground music options be reviewed and approved by the local AHJ. Refer to the following illustration for details on
DIP switch placement in the ON and OFF positions.
