3.2 INSTALLATION PLACE SELECTION
3.2.1 Detection range
The radar’s detection range depends largely on the shape of the objects and on the interfering
reflections in the environment. In general, the larger the reflecting area, the higher the detection
range. The more objects in the measurement lobe, the lower the detection range. This is also the case
for tree branches and bad weather conditions (heavy rain).
The average range, measured on a straight and flat road is 80 m for little cars, 100 m for standards
vehicles and more for large vehicles and lorries. The best range is reached with an installation at 1,50
m to 2,50 m height (lower edge of the display panel).
3.2.2 Installation and measuring angle
The best measurement angle is along the lane axis, which would mean installing the display in the
middle of the lane. Since this is obviously not feasible, install the display on the pavement between 1.5
m and 2.50 m height.
The mounting system at the backside of the display allows it to be mounted on existing lighting or
signalling poles, with standard collars. If the range is not sufficient, you have to orientate the display
so that the detection area of the radar points to the vehicles driving towards it. The angle with the lane
must be as small as possible.
The indications are given for a flat road and a vertical pole. If
the angle between the road and the installation pole is not
90°, please compensate the slope or the pole tilt.

13
3.3 ON FIELD INSTALLATION
1. Place the upper clamp:
2. Hang the unit on the upper clamp with the
upper hook:
3. Secure the installation by mounting the lower
clamp:
4. Slope/tilted pole: compensate the slope or
the tilt.
5. Power the system:
-Battery
-Solar panel
-Public lighting
-230 V network
3.4 POWER SUPPLY
Your reseller offers several power kits.
3.4.1 Mobile kit
Composition:
-A 12 V 24 AH battery
-A 3-steps network charger (Figure 1,marks 25 and 17): when charging from the grid, a
red/orange indicator lamp is lit on the external charger. The battery is fully charged when
the green lamp is lit.
After placing the battery in the slot, connect the plug of the battery into the socket, and close the slot
with the screws to ensure the water tightness.
3.4.2 Solar power kit
The kit is composed by a 12 V 24 AH battery and a solar panel. The solar regulator is mounted inside
the unit.
3.4.2.1 Mounting and installation
Place the solar panel on a mast, according to the manufacturer’s instructions. Turn it to the south,
avoiding shadow. For the mounting of the Icoms’ solar panel, see further in this document, p. 55.

14
1. Insert the battery in the slot, as for the mobile kit, and switch it on.
2. Connect the solar panel above the service box (Figure 3, p. 10, mark nr 8).
Please first switch the battery on, before connecting the solar panel.
If you prefer using your own solar panel, the female connector is available as an option (mark 23).
3.4.2.2 Solar regulator
The solar regulator is mounted in the service box. Different LEDs indicate the state of the material:

15
3.4.3 Public lighting kit
Composition:
-A 12 V 24 AH battery
-A 110 V - 220 V power unit
The battery is to be placed in the slot, like for the mobile kit. The connector for the main is above the
service box (Figure 3, p. 10, mark nr 8) .
To maintain the watertight integrity of the unit, please place the caps on the parameter encoder and
on the USB plug. Ensure that you close the battery slot with the delivered screws.

16
4PREDEFINED SETTINGS
4.1 IN GENERAL
The I-SAFE settings take in account different parameters. The user can define up to 4 speed thresholds,
each of these thresholds can be associated with a colour and with 1, 2 or 3 different successive texts
or pictograms.
Example: between 10 and 49 km/h, each speed measurement appears in green, with a “Thank you”
message, followed by a smiley; between 50 and 75 km/h, the speed appears in red, with the text “too
fast!”; above 75 km/h, the speed is no more displayed, but a message with the potential fine appears.
Parameters like an adjustment of the display time or the display flickering can be set with the Icoms
software. See further, p. 24, for advanced functions.
4.2 FACTORY SETTING
The I-SAFE is delivered with different default parameter bundles, adapted to the most common speed
limitations. An encoder, placed in the service box at the back of the unit (Figure 5, p. 11, mark 12)
allows selecting the speed limit adapted to the location.
When powered, the I-SAFE gives the value of the battery load and then « oo ». After 10 sec, it displays
« GO » and starts to measure the vehicles going towards it and displays their speed. The associated
messages depend on the selected position of the encoder (Figure 5, p. 11, mark 12) . If the RS232 or
Bluetooth communication has been established, the delay before measuring mode moves to 4
minutes. This delay is extended by the same time at every communication operation.
Choose the encoder position which is in accordance with the maximum allowed speed on the
installation place (see p.17):
•1 = ZONE 30
•2 = ZONE 50
•3 = ZONE 70
•4 = ZONE 90
•- = TAILOR MADE ZONE 1 (= zone 50 as factory setting)
•= = TAILOR MADE ZONE 2
•≡= TAILOR MADE ZONE 3
See section 4.3, p. 19, for the texts/pictograms setting and for the “tailor made”zone”.
