For the following, we recommend a separate line with clean power, resistors, protectors and filters whenever possible.

• POWER: The system requires a fused circuit at a minimum of 12VDC at 15 amps measured at the QUANTUM.

• INTERLOCK: A brake or safety interlock signal is required. Note that the brake/safety interlock and ignition signals can be supplied in 12 VDC’s with any installation.

Additional Electrical Notes: : At constant voltages below 10V the QUANTUM will go into a protective state. Additionally, QUANTUM features internal protection against power spikes and Electrostatic Discharge (ESD) to approximately 10,000 volts. All Electro-Mechanical Interference (EMI) is protected coming into the unit, and the QUANTUM does not discharge any EMI.

Layout drawings and shell CAD are available from our Applications department. We can provide all necessary information needed to show the space requirements, including the minimum ADA requirements along with our own recommendations for layout (ie: beyond minimum ADA requirements). Many of these drawings have already been shared with several OEMs.

QUANTUM can only be used with our operator interface, which is two industry standard automotive ‘rocker’ switches (both installed at the operator dash control panel). Our custom designed switches show how the QUANTUM operates and works in conjunction with our operator instruction and training material relevant to the operators’ needs (see specifications on operator interface).

The QUANTUM arms were designed with the thinnest profile achievable, and will work with ‘thin’ flip theater-style seats. Even the contour on the outside of the arm lends itself to work well with the city bus frame gussets.

The sole QUANTUM requirements from the vehicle are a constant 12V power source, and an interlock or vehicle breaking signal to determine that the vehicle has safely stopped. These signals can come from several locations to be determined by the OEM, including their I/O system. With these provided to the QUANTUM, our system drives signal to/from our remote components (i.e.: operator and user interfaces).

The ‘ON/OFF’ switch has 5 terminals, and the ‘SEC/REL’ switch has 10.

Yes, the QUANTUM is installed via a mounting plate that will allow it to be installed and removed from within the vehicle for servicing/maintenance/replacement (if needed). The QUANTUM is attached onto the plate via four threaded studs and a locking nut, and is also attached to the fixed backrest via four screws at the back of the unit. Technicians will be able to remove the side hardware covers and the backrest panel to gain access to the screws. Additionally, they will be able to unplug the QUANTUM via the cable harness connector.

The QUANTUM lighting system was designed as a visual warning indicator for arm movement into the aisle, and to signify securement of the system. We chose a level of lighting that can be seen in daylight, serve as a visual warning and yet not remain a visual deterrent that brings unwanted attention to the wheelchair passenger area.

ON: Activates the QUANTUM station User Interface(driver or user can operate unit)

OFF: The QUANTUM station User Interface is disabled (only the driver can operate the unit)

SECURE: Will initiate the wheelchair securement process

RELEASE: Will release the wheelchair and bring the QUANTUM arms back to stowage

INTERLOCK NOTE: The QUANTUM unit remains interlocked and can not be bypassed by the above controls. This means that drivers may not secure or release the QUANTUM arms when the vehicle is moving.

Thanks to a low G environment and the rear-facing backrest, the QUANTUM is able to apply a minimal amount of force onto the wheelchairs: totaling approximately 50lbs of force divided onto both sides. There are two squeeze modes referred to as an initial squeeze and a final squeeze.

• The Initial Squeeze is when the QUANTUM arms first come into contact with the wheeled mobility device. For safety purposes, the initial squeeze captures the chair at approximately 25 lbs. and alerts the driver that QUANTUM is prepared for full securement, allowing the operator time to ensure there are no concerns before proceeding.

• The Final Squeeze occurs when the driver pushes the button on the driver interface on his dashboard, moving the mobility device pressure to approximately 50 lbs. of force. It’s important to note that if the driver does not acknowledge the mobility device passenger by pressing driver interface button and starts to drive the bus, the QUANTUM will proceed with the Final Squeeze automatically to ensure the safety of the passenger.

Lead time for the QUANTUM is 90 days. We are working towards reducing the lead time, especially for instances such as retrofits and other instances where longer lead times may not be possible.

QUANTUM ships with:

• Installation Manual
• Use and Care Manual
• Operator Placard
• User Placard
• Quick Reference Guide

The QUANTUM ships with everything needed for an installation in a single box. Once received by the OEM, individual packages within the QUANTUM box can be separated depending on the OEM’s assembly line needs. For example, the electrical wiring harnesses and interfaces will be in a single box, yet still packaged with the complete unit received by the OEM. We anticipate it will be possible to ship the components separately in case an OEM has multiple manufacturing sites.

The QUANTUM comes with a driver interface and a user interface that is installed against the wall or seat at the wheelchair passenger position.

• Preventative Maintenance: A Preventative Maintenance schedule includes a checklist for functional testing to be performed along with regular vehicle preventative maintenance schedules

• Arm Grips: The arm grips feature a very durable over-molded rubber. While we don’t anticipate normal wear and tear to cause any visible damage to the rubber, the design of the QUANTUM has anticipated field replacement of the grips and will be available if required.

The QUANTUM backrest is available in both black and dark grey; made of durable vinyl and is designed to be neutral against different fabric and color schemes throughout vehicle fleets.

A stanchion is not required for the QUANTUM. However, the QUANTUM features two mounting provisions to allow customers to attach stanchions if that is their preference. QUANTUM is a stand-alone system.

The user interface is mountable onto any flat surface, including the underside of theater-style flip up seating. Theater-style flip up seats may also be purchased from seating manufacturers with the QUANTUM User Interface pre-installed.
