Engine 791 began as a demonstrator unit for Rosenbauer until September 2017. Princeton (TX) Fire Rescue contracted to purchase the apparatus at that time, and the engine was configured to meet the needs of the department. Engine 791 was officially placed into service on June 1, 2018.
The cab (65-inch with 11-inch raised roof) and chassis are the RBM Commander R611model with cab seating for 5 provided. An EMS cabinet is centered along the rear cab wall. An auxiliary AC unit mounted on the roof provides additional climate control. Both cab and the Crossfire EXT Model body are mounted on the Commander chassis with extruded aluminum construction. Roll-up compartment doors are part of the body package. Rescue-style compartments are mounted on top of each body side.
Power is provided by a 450-hp Cummins ISL9 engine and an Allison EVS 3000 6-speed transmission with pushbutton shifter. A 7.9-kW generator featuring Rosenbauer’s Green Star Idle Reduction technology is mounted at the front of the body. A Weldon V-MUX electrical system with a Vista IV display is also featured.
The apparatus features a Rosenbauer N1500 1,500-gpm, single-stage pump (midship) and a UPF 700-gallon tank. The front bumper tray carries 100 feet of 1¾-inch hose preconnected hose along with an additional 150 feet of 1¾-inch hose. Two speedlays of 1¾-inch hose (200 feet each) and one speedlay with 200 feet of 2-inch hose are located in an enclosed compartment adjacent to the pump panel. The hosebed carries 800 feet of 4-inch LDH and 500 feet of 3-inch hose. An Akron Model 3440 DeckMaster monitor is mounted on top of the right side of the body. A Hannay booster reel with 150 feet of ¾-inch inch hose is located in the right rear compartment. Foam capabilities are provided by an FRC Turbo Foam TFC system with a 50-gallon (20A and 30B) foam cell. Foam is plumbed to the front jump line, the speedlays, and the booster reel. Ground ladders are mounted to a hydraulic ladder rack on the right side of the body.
The warning lights include a Whelen Ultra Freedom light bar (72-inch) and Whelen M6, M7, and M9 lights on the body perimeter. A Roto Ray is mounted on the cab face, and a Whelen Model #TANF85 Traffic Advisor is mounted on the rear of the body. Scene lighting is provided by FRC Spectra lights on the brow and body sides. Audio warning devices include a flush-mounted Federal Q2B and a Whelen Model 295HFS2 electronic siren module with 2 Federal Dynamax ES100 speakers mounted through the front bumper.
This unit is Princeton’s first in the newly adopted dark blue over red livery.
