Dupline Car Park System
Type GP62x022xx724-US
Ultrasonic Sensor

The ultrasonic sensor is part
of the car park system which
contains other variants of
sensors, monitors and dis­plays.
The GP62x0 22xx 724­US sensor is installed in the
middle of the ceiling above
the parking bay and detects
whether a car is parked in the
bay. The parking bay status
is indicated using the built in
LEDs, for GP6220 2201 724­US or GP6220 2202 724-US.
The GP6240 2224 724-US
has not built in LED, but uses
the passive LED indicators
GP6289 000x-US to show the
status.
E.g. green LED indicates that
the parking bay is available for
parking.
A red LED indicates that the

Each sensor need to be con­nected to the Dupline 3-wire
bus. The bus provides power
and enables the sensors to
transmit the status of the park­ing bays to the carpark moni­toring devices (GP3482 9091

724), which keep track of the
number of free parking bays in
an area and show the result on
the connected displays.
The sensors GP62x0 22xx
724-US can also be used for
detection of cars in a count
system together with GPMZC­SET. The sensor has a mode
designed for rapid detection
of cars which can be used in a
count system. Please refer to
the MZC Installation manual.

Water and condensation-resistant The bottom part plus

sensor has been
designed in a such a
way that water entering
from the ceiling flows
right through the sensor
and out of small holes

in the transparent part
of the sensor without
getting in contact with
the electronic board and
without doing any dam­age.

Mode of Operation

The ceramic sensor emits
an acoustic signal at a fre­quency of 40 kHz which is
reflected when it hits the floor
and returned to the sensor.
The reflected signal indicates
whether the parking bay is
available or occupied.

Sensor

addresses

• Status

Dupline® address
The Dupline bus address
used by the sensor to trans­mit the status of the parking
bay. The same address can
be used to force the red LED
ON** for booking of free park­ing bays (this feature requires
management by central PC
software). Please refer to
the Dupline Carpark system
manual for further information
about the Dupline addressing
scheme and the rules that
apply for the assignment.

• Calibration

Dupline

®

address

This address is used to trig-

ger the sensor to perform a
self calibration. Several sen­sors can be given the same
calibration address, thereby
making it possible to cal­ibrate multiple sensors at
once by sending a single trig­ger signal on that address.
The programming unit
GP73800080 is used to send
out the trigger signal.

Modes

The sensor has two modes.
Normal mode or Lane mode.

In Normal mode, the sensor
detects the presence of a car
in the parking bay and lights
the red LED**. See fig. 1 on
page 4. At the same time
the sensor sends a signal
out on the

Dupline® 3-wire
bus. When the parking bay
is empty the LED will change
to green** and also send a
signal out on the

Dupline

®

3-wire

bus.

The sensor will not react to
objects lower than 0,3 m.
To avoid a weak signal, the
sensor must be installed
pointing directly at a hard
surface, as for instance con­crete. A soft or uneven sur­face will reduce the signal.

In Lane mode, the sensor is
designed to be mounted in
the ceiling above the lane.
The sensor is able to detect
moving cars with a maximum
speed of 20 km/hour. See fig.
2 on page 4.
When the sensor detects a
moving car it sends a signal
to the Carpark system that
count down the total amount
of free places, and show
the reduced amount on the
local display but also on the
display that show the total
amount of free places.
This is to prevent to many
moving cars in a specific car­park area. The sensor does

not show the actual status on
the LED’s. The LED’s** only
works as feedback during
calbration, startup and show
the fail status.

Sensor used as “count sen­sor” with the MZC

The sensor can also be used
in a count system, where rap­id detection is needed. When
two sensors are mounted in
the ceiling after each other,
the connected GPMZC can
detect the cars and also
the direction in which the
cars are going. The “Lane
Mode” that is used for sen­sors in “count mode”, has
additional functions where
the installer can program
the sensor to detect cars
with different velocities. The
LED is programmable to be
either selected or deselect­ed. Please refer to the MZC
installation manual for further
information.
