electric control valve, switched independently in the cab. The discharges shall be equipped with removable ground sweeps <br />nozzles angled accordingly with a 180 degree total front sweep pattern. The flow rate shall be 15-30 gpm. <br />Each nozzle shall have a custom fabricated brush guard installed to protect from damage when off road. The valves and <br />manifold shall be protected from damage by the front bumper and skid plate. <br />100261.2 - FOAM SYSTEM <br />A FoamPro part number S106-1600/2.0 electronic foam system shall be provided. The system shall be designed for use with <br />Class A foam concentrate. The foam proportioning operation shall be designed for direct measurement of water flows and <br />shall remain consistent within the specified flows and pressures. The system shall be capable of accurately delivering foam <br />solution as required by applicable sections of the NFPA standards. <br />The system shall be equipped with a control module suitable for installation on the pump panel. There shall be a <br />microprocessor incorporated within the motor driver that shall receive input from the system's flow meter, while also <br />monitoring the foam concentrate pump output. The microprocessor shall compare the values to ensure that the desired <br />amount of foam concentrate is injected onto the discharge side of the fire pump. A "foam capable" paddlewheel-type flow <br />meter shall be installed in the discharge side of the piping system. <br />The control module shall enable the pump operator to: <br />1. Activate the foam proportioning system <br />2. Select the proportioning rates from 0.1% to 1.0% <br />3. See a "low concentrate" warning light flash when the foam tank level becomes low and in two (2) minutes, if the foam <br />concentrate has not been added to the tank, the foam concentrate pump shall be capable of shutting down. <br />A 12-volt electric motor driven positive displacement plunger pump shall be provided. The pump capacity range shall be 0.1 <br />to 1.7 GPM at 200 PSI with a maximum operating pressure of 400 PSI. The system shall draw a maximum of 30 amps at 12 <br />volts. The motor shall be controlled by the microprocessor which shall be mounted to the base of the pump. It shall receive <br />signals from the control module and power the 1/3 horsepower electric motor in a variable speed duty cycle to ensure that <br />the correct proportion of concentrate is injected into the water stream. <br />A full flow check valve shall be provided in the discharge piping to prevent foam contamination of the fire pump and water <br />tank. A 5 PSI opening pressure check valve shall be provided in concentrate line. <br />Components of the complete proportioning system as described above shall include: <br />1. Operator control module <br />2. Paddlewheel flow meter <br />3. Pump and electric motor/motor driver <br />4. Wiring harnesses <br />5. Low level tank switch <br />6. Foam tank <br />7. Foam injection check valve <br />8. Main waterway check valve <br />9. Flowmeter and tee with NPT threads. <br />The foam system shall be installed and calibrated to manufacturer's requirements. In addition the system shall be tested <br />and certified by the apparatus manufacturer to applicable NFPA standards. <br />The foam system design shall be tested and pass environmental testing in accordance with SAE standards. An installation <br />and operation manual shall be provided for the unit. The system shall have a one (1) year limited warranty by the foam <br />system manufacturer. <br />The FoamPro 1600 Series foam system shall be provided with a six (6) foot control cable from the controller to the foam <br />pump assembly. The FoamPro 1600 Series foam system shall be provided with a standard pump panel mounted FoamPro <br />control head. <br />A FoamPro part number 2660-0032 brass flowmeter shall be provided. The flowmeter shall be installed in the "foam capable" <br />discharge line. The flowmeter shall have maximum accuracy between the flow range of 15 GPM and 520 GPM and be <br />capable of operation between 5 GPM to 625 GPM. The tee shall have NPT and Victaulic inlet and outlets connections. <br />A FoamPro part number 6032-0018 instruction and system rating label shall be provided. The label shall display information <br />Skeeter Brush Trucks Page 9 12/03/2020134
