SmartFOAM
DUAL TANK SYSTEM SELECTION
The following procedures are provided for operation with the
Hale ADT or MDT II Selectors.
CAUTION!
UNLESS ENGAGED IN CLASS “B” FOAM OPERATIONS,
THE HALE SMARTFOAM ADT TOGGLE SWITCH OR
HALE SMARTFOAM MDT II SELECTOR HANDLE MUST
B
E IN THE TANK “A” POSITION. IF THE TOGGLE
SWITCH OR SELECTOR HANDLE IS IN THE FLUSH
POSITION WHEN THE FOAM PUMP IS STARTED, THE
FOAM PUMP RUNS FOR ONLY TWENTY (20) SECONDS,
THEN SHUTS DOWN.
Figure 56 : Dual Tank Selector Operating Positions
Make sure the Hale SmartFOAM is operating and foam
solution is being discharged (see Figure 56
: Dual Tank
Selector Operating Positions ).
1. Set the Hale ADT toggle to the desired TANK, or
turn the Hale SmartFOAM MDT II handle until the
indicator points toward the desired TANK.
2. When changing toggle switch or selector handle
position, move smoothly from the TANK
“ A” position
through the FLUSH position to TANK “B” position in
one motion without stopping. With the fire pump
discharging water and the Hale SmartFOAM
operating, a small volume of water is provided to
separate the two foam types helping to prevent
possible adverse reactions.
3.
After completion of Class “B” foam operations,
briefly FLUSH the foam pump and return the Hale
SmartFOAM to the ready condition by returning to
the T
ANK “A” position and flowing a small amount of
Class “A” foam concentrate.
IMPORTANT!
MAKE SURE THE HALE SMARTFOAM DUAL TANK
SYSTEM IS IN THE TANK “A” POSITION WHEN
APPARATUS IS PLACED IN THE READY CONDITION.
The SmartFOAM controller keeps track of which foam has
been selected via the selector handle and if that foam has
been run through the pump (see Figure 57
: SmartFOAM
Foam in Pump Indicator ). The small round icon in the bar
graph indicates what foam is currently in the pump: A, B, or
CLR.
The SmartFOAM will display a warning message indicating
that a FLUSH operation must be performed if the operator
switches from one tank to the other without first FLUSHING.
The SmartFOAM controller will not allow operation of the
new tank until a FLUSH operation is performed.
