PRODUCT FAQ

What are the Electrical requirements of the QUANTUM?

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

 

  • POWER: QUANTUM requires a fused circuit of minimum 12VDC at 20 amps or 24VDC at 10 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 either 12 or 24 VDC with any installation.

 

Additional Electrical Notes: At constant voltages below 11.5v, 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.

Are drawings or CAD available?


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

Can an OEM use their own controls for the driver interface?

QUANTUM can only be used with our driver control interface, which is two standard automotive ‘rocker’ switches (two, installed on the driver steering panel). Our custom designed switches show how the QUANTUM operates and also works in tangent with our driver instruction and training material relevant to the drivers’ needs (see specifications on driver interface).

Does the QUANTUM work with side facing flip seats?

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

Will the QUANTUM interface with OEM Input/Output (I/O) systems?

QUANTUM’S sole 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 (ie: driver and user interfaces).

What are the specifications on the driver interface?

Quantum Driver InterfaceTwo 43mm x 24.3mm Rocker Switches with Blue/White LED illumination rated to 20 amps 12V.

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

Can the QUANTUM be removed from inside the vehicle?

Yes, 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.

How bright is the Quantum LED lighting on the rotating arm?

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.

How does the Driver Interface operate?

Quantum Driver InterfaceON: Activates the QUANTUM station User Interface(driver or user can operate unit)

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

SECURE: Will initiate the wheelchair securement process

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

INTERLOCK NOTE: 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.

How much pressure is applied to a wheelchair?

Thanks to a low G environment and the rear-facing backrest, 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 him time to ensure there are no concerns before proceeding.

 

  • The Final Squeeze occurs when the driver acknowledges via the driver interface on his dashboard, moving the wheelchair pressure to approximately 50 lbs. of force. It’s important to note that if the driver does not acknowledge and starts to drive the bus, the Quantum will proceed with the Final Squeeze automatically to ensure the safety of the passenger.

What are the lead times?

Lead time for 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.

What documentation comes with the QUANTUM?

QUANTUM ships with:

  • Installation Manual
  • Use and Care Manual
  • Driver Operator Placard
  • User Operator Placard
  • QUANTUM Manual ‘Quick Key’ featuring a laminated instruction card for manual operation
  • User Guide: gives a background and a how-to-use to wheelchair passengers. This may be strictly digital.

Will the Quantum ship with everything needed for an installation?

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.

What are the interface options for the QUANTUM?

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

What is the expected Maintenance on the Quantum?

  • 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.

What additional testing has been performed?

Salt spray testing, Drop testing, EMC testing for EU regulations, Destructive Testing, vibration testing, movement test, crash test at 8G, Static Pull testing on QUANTUM with Backrest, Humidity testing, Water Ingress testing.

Can the Quantum backrest fabric be matched to the vehicle seating?

The QUANTUM backrest is only available from Q’STRAINT in a black and dark grey durable vinyl color and designed to be neutral against different fabric and color schemes throughout vehicle fleets.

Is a Quantum stanchion required?

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.

Can the user interface be mounted on the wall flip-up seat?

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