SmartFOAM
SYSTEM OVERVIEW
The Hale SmartFOAM Foam Proportioning Systems are
completely engineered, factory matched foam propor-
tioning systems that provides reliable, consistent foam
concentrate injection for Class “A” AND Class “B” foam
operations. The 1.7AHP and 2.1A systems are for Class
“A” only while the 3.3, 5.0, and 6.5 systems can use
Class “A” and Class “B”.
Hale SmartFOAM Foam systems accurately deliver from
0.1% to 10.0% (up to the capacity of the foam pump)
foam concentrate through a check valve/ injector fitting,
directly into the water discharge stream. It is then fed as
foam solution into a standard fog nozzle, an air aspirated
nozzle, or CAFS equipment, through the apparatus dis-
charge piping. A properly configured and installed foam
system with Hale recommended components virtually
eliminates contamination of the booster tank, fire pump
and relief valve with foam concentrate.
Optionally, the SmartFOAM system can be controlled
by/integrated into a SAM system. See the SMARTFOAM
CONTROL UNIT paragraph (below) for more details.
ROTARY PLUNGER PUMP (1.7 AHP, 2.1A)
The heart of the Hale SmartFOAM 2.1A and 1.7AHP
systems are an electric motor driven rotary plunger
pump. The pump is constructed of anodized aluminum
and stainless steel and is compatible with most Class
“A” foam concentrates. The pump is close coupled to the
electric motor thereby eliminating maintenance of an oil
filled gearbox.
A relief valve mounted on the foam pump and con-
structed of brass, protects the foam pump and foam
concentrate discharge hoses from over pressurization
and damage.
ROTARY GEAR PUMP (3.3, 5.0, 6.5)
The heart of the Hale SmartFOAM 3.3, 5.0, and 6.5 sys-
tems is an electric motor driven rotary gear pump. The
pump is constructed of bronze and stainless steel and is
compatible with almost all foam concentrates. The pump
is close coupled to the electric motor thereby eliminating
maintenance of an oil-filled gearbox. A relief valve
mounted on the foam pump and constructed of stainless
steel, protects the foam pump and foam concentrate dis-
charge hoses from over pressurization and damage.
SMARTFOAM CONTROL UNIT
The control unit can be stand alone or integrated into a
SAM system. If integrated into a SAM system, the SAM
Control Center provides foam specific presets which are
associated with a foam capable discharge. In addition, if
foam is used often, a foam specific Quickset can be pro-
grammed and displayed on the SAM Control Center in
the Quickset area of the screen. Reference Operation In-
stallation Maintenance Manual For Hale SAM (Genera-
tion 2) (FSG–MNL–00210).
When integrated with SAM the SmartFOAM CAN bus
(connector B) must be bridged with the SAM Green CAN
bus. Use SmartFOAM control unit (display) connector C
to connect the SmartFOAM system as a node on the
SAM Green CAN bus.
The SAM Control Center is ONLY capable of initiating
foam via preset 1 (from the foam system display) and
ONLY for a single type of foam (typically type A)., all
other foam operations (switching foam types, flushing,
etc.) must be accomplished from the foam control unit.
The SmartFOAM control unit, mounted on the operator
panel, can also be used as a single control point for the
SmartFOAM system. Press one of the preset buttons to
enable foam concentrate injection once water flow has
been established. The 4.5 inch direct sunlight viewable
color display shows:
❑
Water flow rate
❑
Foam concentrate injection percentage
❑
Total water flowed
❑
Total foam concentrate used
❑
Foam pump capacity
The SmartFOAM control unit also provides plain-text in-
formation and warnings as well as tutorials for calibra-
tion. The user interface can be configured for the mod-
ern SmartFOAM look or the classic FoamLogix look.
WATER FLOW SENSOR
Foam concentrate injection rate is controlled by a com-
puter chip in the control unit for accurate, repeatable, re-
liable foam concentrate injection. A water flow sensor
constantly monitors water flow through the discharge
piping. The information from the flow sensor is provided
to the control unit by a shielded cable. When the Smart-
FOAM system is activated at the control unit a signal is
sent through the control cable to the motor controller to
begin foam concentrate injection. The motor controller
then provides power to the electric motor. The electric
motor rotates the foam pump and foam concentrate
flows through the foam pump discharge to the one piece
check valve/injector fitting into the water discharge
stream.
Note: All Hale SmartFOAM Foam systems require a flow
sensor for operation.
FEEDBACK SENSOR
A feedback sensor in the foam pump discharge
measures foam concentrate flow. The water flow rate
and foam concentrate flow rate are constantly compared
by the computer chip in the control unit.
The motor speed is constantly adjusted to maintain the
operator selected foam concentrate injection rate. Since
the system is flow based, injection rate remains constant
regardless of changes in system pressure or the number
of discharges that are open (within the limits of the sys-
tem).
The maximum rated foam concentrate flow, in gallons
per minute, is denoted by the model number.

pacity at various foam concentrate injection rates for the
