RPP0012 is the 24 VDC BCE battery charger board assembly for Tornatech diesel fire pump controllers, covering both the 1st-generation models (2DIE027/2DIE033) and V1 VIZITOUCH GPD controllers. The board maintains the controller's 24-volt engine-starting batteries so the diesel is ready to crank the moment a fire pump demand occurs.

Suspect the charger board when the controller raises battery or charger trouble alarms, when battery voltage sags below specification, or when batteries that test healthy on the bench still will not hold charge in the controller. Replacing the complete board assembly restores factory charging performance without rewiring the cabinet.

Fits Tornatech 1st-generation (2DIE027/2DIE033) and V1 VIZITOUCH GPD diesel fire pump controllers — note this is the 24 VDC version; the 12 VDC board (RPP0002) is listed separately.
