Wireless Space Count: SENSIT
1 INTRODUCTION
The W ireless Space Count system facilitates accurate measurement on occupancy of indiv idual parking
spaces in car parks, and on-street parking spaces. This information can be used to guide traffic to free
parking spaces but can also be used for on-street parking enforcement and overstay detection. For onstreet enforcement the number of occupied parking spaces can be compared with the number of
payments realized by the pay station. For overstay detection the system alerts instantly a parking officer
to the presence of nearby overstaying v ehicles. Based on this information you can exactly determine
which space to enforce.
1.1 SENSIT
The SENSIT are mounted into the floor of each parking space. The SENSIT is suitable for floor mounting
as well outdoor as indoor. The SENSIT are featured with detection and communicate wireless with each
other, creating their own network. The SENSIT do not require power wiring, in contrast to conventional
systems that require wiring throughout the car park and mounting onto the ceiling.

2 INSTALLATION SENSIT
2.1 SAFETY PRECAUTIONS
The following safety precautions should be observed during normal use, service and repair.
• The SENSIT may only be installed and serviced by qualified service personnel.
• To be sure of safety, do not modify or add anything to the SENSIT other than mentioned in this
manual or indicated by NEDAP N.V.
2.2 DIMENSIONS
The SENSIT is designed for mounting into the floor of a parking space. See Figure 1 for the dimensions
of the unit in mm. The front of the SENSIT is laser engraved with the node ID number, see Figure 2.
Figure 1: Dimensions SENSIT
Figure 2: Top and bottom laser engraved sides of the SENSIT
The node ID is mentioned on the top of the housing under ID. There is also a 125kHz passive RFID label
embedded into the SENSIT. This can be used for verification of the SENSIT or to localize the SENSIT
on the parking lot.
2.3 REPLACEMENT
When the battery life of the SENSIT fails after specified life time, we advise to replace the unit
completely. The SENSIT is fully sealed and for outdoor use therefore batteries cannot be replaced.
Drill out the old SENSIT and complete the mounting procedure as describe in the next paragraph.

2.4 MOUNTING PROCEDURE SENSITS
Below the mounting procedure for the SENSIT.
Step 1: Distribute the SENSIT over the empty parking lot (without mounting them into
the floor).
Step 2: All SENSIT are set to transport/stock mode during shipment. Prior to installation
all SENSIT must be swept with a strong magnet. This will give the SENSIT a
reset. Please ensure to use a strong magnet (Neodymium).
Note: Once out of the transport/stock mode the battery lifetime starts to count.
Step 3: Write down the node ID number on your installation plan so you are sure which
SENSIT is positioned in which parking bay.
Step 4: Verify if all the SENSIT are online and if communication is received by the
SENSIT DATACOLLACTOR after the magnet sweep. Do this prior to mounting
the units into the ground.
Note: Only once all SENSIT are live and seen in the software they can be
installed into the pavement.
Step 5: Drill a hole of 85 mm (
3.35 in
) into the
centre of the parking bay.
Step 6: Use the right amount of filler
Step 7: Double-check the node ID number
and the parking bay on the
installation plan and place the
SENSIT into the hole

Step 8: After installation the SENSIT must be calibrated with no car on top of the sensor
or on neighbouring parking bays.
Note: When the SENSIT are not calibrated they hardly send any messages.
This is due to the fact that there are no events generated because the
magnetic tressholds are not crossed.

3 PROJECT SUPPORT
Based on our thorough project analysis including configuration and installation advice we can offer the
customer the best AVI solution.
3.1 SITE SURVEY & INSTALLATION ADVICE
This will consist of an engineer visiting the site to visually inspect and analyze the location. We will then
carry out calculations and provide you with detailed configuration and installation advice for the Wireless
Space Count equipment for a specific project.
3.2 ON-SITE CERTIFICATION
An engineer will visit the site to inspect the installation of the equipment on reliable and accurate
detection. Nedap engineers are not involved in installation (wiring) of any equipment. The installation
must be completed before the engineer arrives on-site. We will ensure that the operation confirms our
commissioning requirements, only on condition of prior given installation advice.

4 FCC AND IC DECLARATION
4.1 Compliance statements (part15.19)
This device complies with part 15 of the FCC Rules and to RSS210 of Industry Canada.
Operating is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired
operation.
4.2 Warning (part15.21)
Changes or modifications not expressly approved by party responsible for compliance could void the
user’s authority to operate the equipment.
4.3 RF Exposure (OET Bulletin 65)
To comply with FCC RF exposure requirements for mobile transmitting devices, this transmitter should
only be used or installed at locations where there is at least 20cm separation distance between the
antenna and all persons.
4.4 Information to the User (Part 15.106(b))
Note: This equipment has been tested and found to comply with the limits for a class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates uses and can radiate radio
frequent energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does not cause harmful interference to radio or television reception, which can be determine
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
- Reorient or relocate some node
- Consult the dealer or an experienced radio/TV technician for help.
