The constant comparison of the water flow and foam flow information by the AccuMax system ensures the
desired proportion of foam concentrate, based on water flow rate, independent of any variations in fire pump intake or
discharge pressures. As water flow increases or decreases, the foam concentrate rate of injection is increased or decreased
automatically to correspond to water flow, maintaining the proper concentrate percentage as selected on the FLI injector.
It also controls the foam control valve to allow the proper amount of foam concentrate to be injected into water manifold
or individual discharge lines based on the input requirements controlled by the fire pump operator and the information
supplied by the foam flowmeter(s) and the water flowmeter(s) regardless of operating pressure.
Each FLI controller operates independently and all FLI assembly(ies) shall communicate with the AccuMax
software for total system operation. With a single-point FLI, one pressure transducer is provided. On multi-point Fusion
system, a specified number of FLI controllers and water pressure transducers are provided; installed on each discharge
(to indicate discharge “line pressure” readings). Foam concentrate shall be injected directly into the water manifold or
into each discharge of specified foam/water discharges.
The water line flowmeter measures the water flow and sends a signal to the display(s). A water pressure transducer
shall be installed on the water manifold (single-point) or each water/foam solution discharge line.
On vehicle mounted systems:
12/24-volt electrical power to operate the foam system shall be provided by the
chassis electrical system.
On fixed systems:
12/24-volt electrical power to operate the foam system shall be provided by a separate battery
and charger system by the installer. In both electrical systems, the final installer shall be responsible for power supply
wiring and fuse protection per the electrical section of the installation manual.
