Introduction:
The Dupline® 3 Parking Guidance system saves time and reduces stress for drivers.
Dynamic displays, strategically positioned throughout the facility, provide ‘space available’ counts and
efficiently guide the driver to vacant spaces with clear and bright green arrows pointing the way.
If there are no vacant parking spaces in an area, the display will show a bright red cross to discourage the
drivers from entering this area. Other displays can be made to show the total number of vacant spaces on a
particular level or in the entire parking facility. Dynamic message displays can also be used in the facility to
provide additional information to drivers. Some examples could be Caution, Construction Ahead, Buckle-Up
or any other message that needs to be communicated to the drivers in the facility.
In the parking space
Space by space, we will focus on the 45-degree sensor for lane mounting. Installation of the vertical sensor
is also explained, but basically, physical installation and precautions are the same for all types of sensors
and LED indicators.
A 45-degree sensor with bright, built-in LEDs is placed in the lane outside each parking space. Eight
different colours, freely programmable, can be selected to show either green for vacancy or red for
occupied. If the space is for disabled parking, the colours become blue and red. The bright LED indicators
provide a visual reference from a distance as drivers search for vacant parking spaces.
The Dupline® Parking sensors utilise a special ultrasonic frequency, much like the one used by bats to catch
flying insects. A sophisticated microprocessor built into the sensor transmits a 40-KHz signal, which hits the
ground. All the echoes it finds are used to decide the bay status. Once detection has been confirmed, the

indicator lights will switch from green or blue to red and the displays and software counts will be accurately
updated as well.
The Software…
The Dupline® 3 Parking Guidance System is inherently robust, and it is a stand-alone system. This system
requires no PC to run, it only needs a PC for system configuration. In addition, Carlo Gavazzi supplies
carpark software, which enables monitoring of the real-time situation of each parking space or level in a
facility. It also has an alarm component, which can provide logging and indication of a variety of conditions
with operator-defined limits.
Some typical alarm functions include time limits for individual spaces, occupied levels and maximum
occupied indications. Additionally, the software graphically displays tables and graphs showing the
occupancy rates for the areas, the levels and the entire facility.
The software is also an excellent tool for data logging and historical trending and analysis. Data can be
stored and utilised for multiple facilities, a single facility, a level, or even for an individual space.
The software allows authorised operators to book or reserve spaces. When an open space is booked, the
associated indicator light in the parking space will turn red, and it will provide a connection to the
software's overview where the corresponding virtual indicator light turns red. The software also provides a
web server that enables access to the carpark system via tablets, smartphones etc.
Planning a Dupline®Parking Guidance System (PGS)
As with any good system, the majority of your time and effort should be spent in the ‘planning’. An old
proverb says: ‘A good plan today is better than a perfect plan tomorrow.’
In this section system planning is divided into four distinct phases. These four phases should be completely
understood and completed before moving on to the actual Installation.
Phase 1: Gather Tools and Information
This includes technical drawings/information/layout of the parking system acquired from the customer. The
drawings used must always be the latest version to avoid any mistakes in the subsequent work.
The drawings should consist of lanes, cross-sections, parking spaces, both regular and for disabled, location
of displays and cabinets, cabinet size, available power and location and the location of the equipment room
where the software server will be installed.
Traffic flow: Single direction or bi-directional.
A true-to-scale CAD drawing with information of the parking structure, including lane distances in order to
determine the cabling and maximum number of sensors allowed per CMCG.
Parking space dimensions: length, width and the distance from the floor to the ceiling. The relationship
between the floor and ceiling angle is also critical.
The dimensions from centre line to centre line of the spaces.
Any information on using existing or new cable trays to pull wires for the sensors

Phase 2: Display Placement, Lane Definition, Sensor Mounting
Define the number of displays based on the natural flow of cars in the parking facility, in cooperation with
the customer. The best way to do this is by making a joint walk-through and drive-through.
Confirm any architectural considerations with the customer regarding signals, finding one's way and any
other equipment to be installed in the parking facility.
Split the parking into segments and use the lanes as a natural part of these segments.
Define the type of displays. Should they simply display an ‘arrow’ and ‘red-cross’, or should they display
space availability counts as well? It all depends on the natural flow and the customer’s requests and needs.
Determine the necessary environmental ratings of the displays in relation to the intended use and
installation. Also take into consideration the accidental ingress of water from plumbing leaks and wind-
blown rain or snow.
Decide if there should be one or more multi-level ‘Tower’ or ‘Monument’ displays installed at the entrance
to the parking structure providing a snapshot of all available spaces on each level.
What should the displays show? Several available spaces in many lanes or just local available spaces from a
single lane.
A maximum of 50 sensors and a maximum of 150 m wire in a line (branch). A maximum of 90 sensors per
generator. General rules based on 1. 5 mm2cable.
Decide whether space-mounted vertical sensors, lane-mounted 45-degree sensors or sensors and separate
LED indicators should be used.
Determine whether the sensor must be mounted directly to the ceiling or in a tray or lowered. Always try
to select the most functional and aesthetic solution in relation to cost-effectiveness.

Decide which spaces should be used as disabled parking spaces. Normally, disabled parking spaces are
placed close to escalators and elevators, and their numbers are determined in accordance with regulatory
laws.
Determine the number and placement of the cabinets. Ideally, they should be placed so that the sensor
loads are equal in all directions. They should be accessible only by ladder or cherry picker so as to be
protected from tampering. The maximum rating of the enclosures should be NEMA 3R or IP54.
Phase 3: Design One Lane (…and Build from There)
As a rule-of-thumb, there is a maximum of 50 sensors and 150 m (490 feet) of wire in a line. The wire must
be an unshielded 14-16 AWG type (1.5mm2). There must be a maximum of 90 sensors per generator. If the
line has less than 50 sensors and the wire length is longer than 150 m (490 feet), please refer to the voltage
drop calculation described in detail in the ‘calculation’ section.
Power supply calculation (the number of sensors determine the size of the power supply). Because of the
pulsating output from the CMCG, always use a double size power supply with power out on 28 VDC. When
using a 28- VDC/2.5- Amp power supply, 50 sensors can be installed in a line. When using a 28 VDC / 5 Amp
power supply, 90 sensors can be installed per generator (CMCG).

The sensor/base must be mounted either on the ceiling or a rail. Daisy-chain all the sensor bases and
display interface modules in the lane with the Dupline® 3-wire bus. Power the system and program the
sensors and displays by means of the SBP2WEB24 programming tool.
Design of the placement of sensors, indicators, cable trays and cabinets.
If you use the 45-degree angled sensor SBPSUSL45, it is essential to mount it at a distance of between 2 and
2.5 m from the floor.
If you use the vertical sensor SBPSUSL, the maximum height must not exceed 4 m (13.2 feet). If so, it is
important that the sensor is lowered by means of ceiling mounting brackets.
The sensor must be mounted with a vertical deviation of maximum +/- 5°.
Using external LED indicator SBPILED, please make sure they are installed in the lane, so that they are
visible for drivers at a satisfactory distance.
Use aesthetic cable rails, where sensors can be installed and cables can be pulled and mounted.
Place cabinets in a logical way with short distances to the lanes to avoid long cables. For example, place
many small cabinets in the area or on the floor or place a big cabinet in the middle of the area or floor.
Phase 4: Dupline®Parking Guidance Software
Use an existing IP network or create a new TCP/IP network.
Determine the number of spaces to be monitored on each level and in total.
Require parking drawings in JPEG, PNG or PDF to be imported into the carpark software.
Seven pieces of SBP2MCG324s can be multi-dropped to a single SBP2WEB24 controller. To enlarge your
carpark system, the carpark server SBPCPY24 can operate with 10 SBP2WEB24 modules.
