1. Rear kit, front and front-back

4 sensor rear kit

It is the simplest and most linear solution. The control unit is normally powered by the reverse lamp: inserting the reverse gear the system is automatically activated, removing it turns off. No additional buttons or timers are needed.

4-sensor front kit

A simple 4 sensor kit can also be installed frontally, but the activation must be decided first with the installer. In fact, there is no natural command equivalent to reverse. It may be necessary to use a button, an external timer, brake impulse or another signal chosen by the professional.

Kit at 8 front sensor + back

Use a two-channel control unit to handle four front and four rear sensors. It is a complete and correct solution, recommended on SUVs, long cars, campers, vans and commercial vehicles.

2. How the detection works

The sensors emit ultrasonic waves and measure the time required to return the signal reflected by the obstacle. The control unit transforms this information into an acoustic sequence: the more the obstacle is close, plus the signal becomes rapid, up to the continuous tone.

The system is a maneuver aid and does not replace mirrors, direct view, camera and driver attention.

3. OEM type sensors and aesthetic result

Fuzion systems use bumper wire sensors designed for an orderly result and close to the original aesthetics. The sensors can be painted with the correct procedure and without accumulating too much material on the sensitive part.

Quick release plugs and shielded wiring help both during installation and in case of future disassembly of the bumper.

4. Correct assembly

Height and distance

The sensors must be positioned at the same height and with regular spaces, respecting the indications of the kit and the shape of the bumper.

Inclination

A sensor oriented too much to earth can detect asphalt, slopes or sidewalks. A super-oriented sensor can lose low obstacles.

Retro bumper

Before drilling you need to check metal reinforcements, absorbers, wiring, sleepers and spaces available.

Painting

Apply thin and uniform layers. Excessive primer and paint can reduce sensitivity.

Wiring

The cables must be fixed away from discharge, moving parts, stagnant water and sharp edges.

5. 4 sensor rear kit: simple automatic activation

The control unit is normally installed in the trunk and connected to the reverse lamp. Activation is completely automatic:

1. reverse is inserted;
2. the lamp provides power supply to the control unit;
3. the rear sensors come into operation;
4. by removing the reverse gear, the system turns off.

It is the fastest configuration and does not require the driver any manual command.

6. Front sensors: because the installation must be designed first

The front should be active during maneuvers, but not continuously while driving. With a simple 4-sensor kit the installer must then choose how to control the control unit.

The possibilities include:

• manual on / off button;
• external timer;
• brake impulse;
• reverse pulse;
• other compatible signal valued by the professional.

The choice depends on the use of the vehicle and the driver's preferences. For this reason the front installation must be agreed before buying or before assembly.

7. How a 8 sensor kit works

The 8 sensor control unit manages a front channel separately and one rear. In the traditional configuration the two channels do not work simultaneously: by inserting the reverse gear, the rear channel takes the priority and the front one is excluded.

This is the logic normally adopted in the 8-sensor aftermarket systems of different manufacturers and does not represent a defect of the fief kit.

The control unit is normally placed in the trunk. As a result, the four cable sensor cables must cross a good part of the passenger compartment to reach the rear control unit.

The Fuzion internal timer

The 8-sensor fuition control unit, on the planned systems, a timer dedicated to the front. The control wire can be connected to the brake, reverse or to another pulse chosen by the installer.

After cessation of the pulse, the front part remains active indicatively for about 20-25 seconds, allowing the maneuver to end. The timer can be used or excluded; A manual button can also be added when necessary.

8. Professional Fuzion "A Art Rule" Configuration

To obtain simultaneous control of the two ends of the vehicle, FUCtion has been using a professional configuration for years composed of two independent systems:

• a 4-sensor fuition kit dedicated to the rear;
• a 8 sensor fuition kit used to manage the four front sensors and exploit the internal timer;
• the rear channel of the 8 sensor control unit remains unused;
• the four unused sensors can be stored as spare parts or intended for other compatible application valued by the installer.

How the configuration works

1. The rear kit is normally connected to the reverse lamp.
2. The front-destined control unit also receives the pulse chosen, normally that of reverse gear.
3. By inserting the reverse gear simultaneously activates the rear and front sensors.
4. Being two independent control units, no canal excludes the other.
5. Removing the reverse gear, the back goes out.
6. The front remains active for about 20-25 seconds thanks to the internal timer.
7. The driver can complete the step forward of the maneuver by continuing to receive the front signal.

Because it can be safer during a real maneuver

During a parking lot between two vehicles it may happen to reverse while the front bumper is simultaneously approached at the corner of another car, to a wall or a stake.

With a single 8 sensor kit, during reverse the front channel is normally excluded. With the Fuzion configuration with two independent systems, instead, in front and behind, simultaneously remain active and the possible front obstacle is reported.

Activation of the front without button

When only a short front assistance is used, it is possible to temporarily insert the reverse to start the timed cycle. By removing the reverse gear, the front continues to work for the expected time without obliging the driver to search or press a button.

A manual command can still be added when the customer or installer want additional management.

Two distinct buzzer: Understand the offshore side

The rear system keeps control unit, wiring and buzzer in the rear area of the vehicle. The front system keeps control unit, wiring and buzzer under the dashboard or in the front position chosen by the installer.

The driver thus receives two reports physically coming from different directions. Even tone and volume can be different, making it more immediate to understand if the obstacle is in front or behind.

Less wiring and up to about three hours of less work

With a single 8 sensor kit, the four front cables must be brought to the control unit in the trunk. With two independent systems, the rear remains in the trunk and the front remains under the dashboard or in the front area.

Thus redundancy of the coatings, passages under knock-ups, crushing risks of cables and processing times. Depending on the vehicle and complexity of the interiors, this configuration can also reduce the assembly of several hours, arriving in some cases to indicative savings up to about three hours of labor.

The initial investment on the products is higher because two kits are used, but professional work savings can compensate in part or completely the difference, simultaneously offering multiple automation and a clearer signal.

Useful also with original rear sensors

The same logic can be adopted when the vehicle already has serial rear sensors. The 8 sensor fuition control unit can be used for the front only, using timer and wiring maintained in the front area.

9. Sensitivity adjustment on the 4 sensor kits

The latest Fuitional units dedicated to 4 sensor kits integrate a lateral sensitivity regulator. The adjustment is gradually carried out with a small screwdriver.

It is important to proceed with minimal variations and try the system after each adjustment. This allows you to better adapt the response to height, bumper inclination, towbar, protruding plaque, vehicle shape and specific installation conditions.

Excessive adjustment or performed without evidence can increase false alarms or reduce detection capacity.

10. Fuition logo, markings, approvals and traceability

Fuition kits are not anonymous products. Control units, packages and components report the FUDIT logo and, according to the specific line, markings and approvals provided, as visible on products.

This allows you to identify the system, verify the origin and distinguish a line followed over time by generic kits without brand, documentation or continuity of spare parts.

Markings and features must always be verified on the package, component and card of the individual product. The presence of a marking does not replace proper installation or verification of the intended use.

11. False alarms: most common causes

• too low sensors;
• sensors inclined towards the ground;
• trailer hook or leaning plate;
• very curved bumper;
• too thick paint;
• dirty, ice or water on the surface;
• sensors exchanged or with unsuitable connectors well;
• damaged or crushed wiring;
• control unit installed in a wet area;
• sensitivity regulated in an incorrect manner;
• very close side obstacles.

A false alarm does not automatically mean faulty control unit. First you need to control position, inclination, cleaning, sensitivity and wiring.

12. Diagnosis, spare parts and continuity over time

When a sensor doesn't work, it is useful to exchange it with a working. If the problem follows the sensor, it is likely that the sensor is defective. If it remains on the same position, you need to control cable, connector or control unit.

Spare parts always available

Fuzion keeps available, second gamma and compatibility, single sensors, control units, buzzers, wiring and accessories. The customer is not forced to replace the entire system if a single component is damaged after years.

This is one of the main advantages compared to anonymous or no longer supported kits: those who buy Fuzion can count on technical assistance and search for correct spare parts even over time.

13. Buzzer and acoustic signaling

The buzzer must be placed in a audible but not annoying position. In separate systems, the front and rear position of the two buzzers helps the driver to recognize the direction of the obstacle.

14. Sensors and backrock

The sensors and backrock can work together. The camera shows the area, while the sensors offer an acoustic notice. None of the two systems replaces attention.

15. Maintenance

• keep the sensors clean;
• check the system after bumps or dismantling of the bumper;
• do not use too close high pressure jets;
• check the connectors after infiltration;
• do not cover the sensitive surface with accessories or adhesives;
• store any sensors not used as spare parts.

16. Fuition and 5-year warranty assistance

The value of a professional system is not only in the first assembly. Fuition follows the customer before and after the purchase, helps to choose the configuration, driving in the cross test and identifies the correct component in the event of an anomaly.

The complete systems provided are covered by 5-year fiction guarantee according to the conditions indicated. It is a cover that is particularly extensive in the aftermarket parking systems market and joins the continuous availability of spare parts.

17. Common errors to avoid

1. Drill without checking behind the bumper.
2. Mount the sensors with different quotas.
3. Orient them to the ground.
4. Paint them with excessive layers.
5. Install the control unit in a wet area.
6. Leave free cables near the drain.
7. Ignore tow hook or protrusions.
8. Install a 4-sensor kit before you decide before you activate it.
9. Assume that the two channels of an 8 sensor kit always work together.
10. Adjust the sensitivity with excessive variations.
11. Confuse a position problem with an electronic failure.
12. Replace everything without trying individual components.
