Demo #3708 Smeal Fire Apparatus Co. 105’ Heavy Duty Aerial ELECTRICAL SYSTEM The chassis shall include a single starting electrical system which shall include a 12 volt direct current Weldon brand of multiplexing system, suppressed per SAE J551. The wiring shall be appropriate gauge cross link with 311 degree Fahrenheit insulation. All SAE wires in the chassis shall be color coded and shall include the circuit number and function where possible. The wiring shall be protected by 275 degree Fahrenheit minimum high temperature flame retardant loom. All nodes and sealed Deutsch connectors shall be waterproof. OEM WIRING The wiring system shall include a custom J1939 interface harness drop provided by the chassis manufacturer to the required specifications required by the OEM. MULTIPLEX DISPLAY The multiplex electrical system shall include a Weldon Vista III display which shall be located on the left side of the dash in the switch panel. The Vista III shall feature a full color LCD display screen which includes a message bar displaying the time of day, the current ambient outside temperature and important messages requiring acknowledgement by the user which shall all be displayed on the top of the screen in the order they are received. There shall be virtual controls for the auto climate control and on-board diagnostics. The display screen shall be video ready for back- up cameras, thermal cameras, and DVD. The Vista III display shall measure approximately 10.38 inches wide X 7.50 inches overall. The display shall offer varying fonts and background colors. The display shall be fully programmable to the needs of the customer and shall offer virtually infinite flexibility for screen configuration options. POWER & GROUND STUD A 40 amp battery direct power and ground stud shall be provided and installed in the electrical distribution panel. The stud shall be size #10 and protected with a 40 amp circuit breaker. EXTERIOR ELECTRICAL TERMINAL COATING All terminals exposed to the elements will be sprayed with a yellow protective rubberized coating to prevent corrosion. ENGINE The power plant for the vehicle shall offer proven performance and reliability while meeting all Federal diesel-engine emission requirements. During acceleration, the electronically actuated variable geometry turbocharger (VGT) shall automatically and precisely boost output across the operating range for improved throttle response and greatly reduced turbo lag. The VGT shall optimize airflow during Jake operation which shall offer increased auxiliary engine braking performance. The Detroit Diesel engine shall achieve the oxides of nitrogen by 55 percent and particulate matter by 90 percent. The Detroit Diesel shall achieve the nitrogen oxide target by optimizing the existing exhaust gas recirculation system. Particulates shall be reduced with the after treatment system, comprised of a Diesel Oxidation Catalyst and a Diesel Particulate Filter (DPF). The engine manufacturer shall be responsible for total engine emissions by the addition of maintenance free crankcase breather and oil separator. The centrifugal oil separator shall send oil droplets back to the sump which shall emit a much cleaner vapor. Revised 3/19/09 Page 78 of 112
Demo #3708 Smeal Fire Apparatus Co. 105’ Heavy Duty Aerial The Series 60 engine shall include an advanced fuel system which shall add performance and cleanliness to the engine. Dual solenoid Electronic Unit Ejectors shall provide exact fuel and metering and enable independent injection pressure control. This system shall have multiple injection capability to maintain performance advantages and improved sound quality. The Series 60 shall be rated at 515 HP at 1800 RPM and shall be governed at 2100 RPM with 1650 foot pounds of torque with peak torque occurring at 1100 RPM for rapid off the line acceleration. The engine shall have an 855 cubic inch displacement (14 Liters). The Series 60 shall include a DDEC VI engine management system. The DDEC VI shall employ a powerful microprocessor, increased memory and enhanced diagnostics. The DDEC VI shall be capable of managing all engine functions and shall be a key strategy in greater operating efficiency and cleaner exhaust emissions. A wiring harness shall be supplied ending at the back of the cab. The harness shall include a connector which shall allow an optional harness for the pump panel. The included circuits shall be provided for a tachometer, oil pressure, engine temperature, hand throttle, high idle and a PSG system. A circuit for J1939 data link shall also be provided at the back of the cab. The engine shall include Citgo brand Citgard 500, or equivalent SAE 15W40 CJ4 low ash engine oil which shall be utilized for proper engine lubrication. ENGINE PROGRAMMING HIGH IDLE SPEED The engine high idle control shall maintain the engine idle at approximately 1250 RPM when engaged. ENGINE HIGH IDLE CONTROL The vehicle shall be equipped with an automatic high-idle speed control. It shall be pre-set so when activated, it will operate the engine at the appropriate RPM to increase alternator output. This device shall operate only when the master switch is activated and the transmission is in neutral with the parking brake set. The device shall disengage when the operator depresses the brake pedal, or the transmission is placed in gear, and shall be available to manually or automatically reengage when the brake is released, or when the transmission is placed in neutral. There shall be an indication on the Vista screen for the high idle speed control. ENGINE PROGRAMMING ROAD SPEED GOVERNOR The engine programming which governs the top speed of the vehicle shall be disabled. AUXILIARY ENGINE BRAKE A Jacobs engine compression brake, for the six (6) cylinder engine shall be provided. The engine compression brake shall actuate the vehicle’s brake lights when engaged. A cutout relay shall be installed to disable the compression brake when in pump mode or when an ABS event occurs. The engine brake shall activate upon 0% accelerator when in operation mode. AUXILIARY ENGINE BRAKE CONTROL An engine compression brake control device shall be included. The electronic control device shall monitor various conditions and shall activate the engine brake only if all of the following conditions are simultaneously detected: a valid gear ratio is detected; the driver has requested or enabled engine compression brake operation; the throttle is at a minimum engine speed position; and the electronic controller is not presently attempting to execute an electronically controlled final drive gear shift. The compression brake shall be controlled via an off/low/medium/high virtual button on the Vista display. Revised 3/19/09 Page 79 of 112
