There are three models of Hale Foam systems covered by this manual. The
Hale FoamLogix Model 3.3 (3.3GPM / 12.5LPM), Model 5.0 (5.0GPM /
19LPM) and Model 6.5 (6.5GPM / 24.6LPM).
The maximum rated foam concentrate flow in gallons per minute is denoted
by the model number. Table 2-1: “Maximum Foam Solution Flows” on page
20 shows the system capacities at various foam concentrate injection rates
for each Hale FoamLogix Model.
The Hale FoamLogix 3.3, 5.0 and 6.5 system configuration is shown in Fig-
ure 2-2: “Foam Pump Installation Envelope Dimensions“ on page 25. Also
see Figure 2-3: “Foam Pump Installation Envelope Dimensions, ADT Option
Only” on page 26.
2.5 TANK SELECTOR VALVES
Selection of the desired foam concentrate tank with the ADT panel mounted
toggle switch or MDT II selector automatically changes the foam concen-
trate injection rate to the preset default rate for the selected foam tank. No
further operator intervention is required.
The ADT, MDT II and MST include the check valves and connection points
to provide foam pump flushing capabilities.
Air Dual Tank Selector (ADT)
The Air Dual Tank (ADT) valve is an air operated foam tank selector valve
that enables selection of foam concentrate dependent on fire ground opera-
tional demands.
The ADT is an integral part of the foam pump and provides an electrical
interlock for the low tank level sensors and concentrate injection rate. A
panel mounted selector toggle switch with indicator lights controls foam con-
centrate tank selection and shows which foam concentrate tank is in use.
Manual Dual Tank Selector (MDT II)
The Manual Dual Tank (MDT II) selector valve is available for the Hale Foam
systems with dual tanks. The MDT II is a panel mounted, manually oper-
ated selector that provides selection of foam concentrate dependent on fire
ground operational demands.
