Installation of a powerful sound signal, often referred to as the “ship roar”, is becoming increasingly popular among motorists who want to protect themselves on the road. The garage in this context is not just a storage place for the vehicle, but a full-fledged workshop where additional equipment is installed. Sound alarms High volume allows you to effectively warn other road users about your approach, especially in conditions of dense traffic or poor visibility.
The process of implementing such a device requires careful preparation, as standard automotive circuits are often not designed to consume current with powerful pneumatic or electrical signals. Garage owners You should understand that we are not talking about a simple replacement of a regular “squeaker”, but about a full-fledged electrical installation. It is in the garage, where there is access to the workbench, tool and outlet 220V, it is most convenient to conduct pre-assembly and testing of the system before installation under the hood.
It is important to note right away that the use of ultra-loud signals is regulated by law, and installing a device whose volume exceeds the permissible limits can lead to fines. However, if sound pressure Selected competently and in accordance with technical regulations, such a signal becomes an effective means of passive security. In this article, we will discuss all the stages of work: from the choice of the model to the final configuration in the garage.
Selection of the appropriate sound signal model
The first step is always the selection of equipment that will meet both the technical capabilities of your car and your personal preferences. The market offers a variety of options, from compact electric “horns” to massive pneumatic systems requiring the installation of a compressor and receiver. Electrical signals Fanfare is the most common type due to its ease of installation and high volume, reaching 130-140 dB.
When choosing, you should pay attention to the supply voltage and the current consumed. Most high-powered models run from 12 or 24 volts, but consume significant current, which requires the use of additional relays. Pneumatic systems They sound more bassistic and realistically mimic the horn of a train or ship, but they are more difficult to install and maintain.
- 🔊 Loudness: Choose models with a range of 120 to 135 dB for effective on-track warning.
- ⚡ Current consumption: Take into account the load on the onboard network, standard signals consume up to 5A, powerful ones - up to 15-20A.
- 💧 Moisture protection: Look for the IP65 marking and above, as the device will be installed in the underhood space.
- 🔩 Shell material: Preferably chrome brass or stainless steel, resistant to corrosion.
⚠️ Attention: By setting the signal louder than 135 dB, you risk creating discomfort for others and getting a fine from traffic police inspectors for violating the rules of operation of vehicles.
You should not chase for maximum power if your car is a compact city hatchback. In that case, meanness It will be more appropriate and safe. For SUVs and trucks, it is permissible to use more powerful systems, since the dimensions of the vehicle require more serious acoustic support for safety.
Required tools and materials for installation
Quality installation is impossible without proper preparation of tools. The garage should be equipped with a basic set of locksmith and electrical tools. First of all, you will need a reliable power supply to test the system before the final fixation. Multimeter It will become an indispensable assistant for checking the integrity of circuits and controlling voltage.
For laying the wiring, it is necessary to stock up on a copper wire with a cross section of at least 2.5 mm2, since standard thin wires can not withstand the current load and melt. You'll also need one. shrink tubes, tape, clamps for fastening and a set of terminals.
- 🔌 Rele: Be sure to use a 4 or 5 contact relay with a switching current of at least 30A.
- ✂️ Tool: Bogocreas, stripper for wire sweep, set of screwdrivers and keys.
- 🛡️ Safety: select a fuse with a nominal value corresponding to the consumed signal current (usually 10-20A).
- 🔦 Lighting: portable lamp or powerful lantern for working in the dark corners of the hood space.
Pay special attention to the quality of the connections. Poor contact in a high-current circuit will lead to heat and possible fire. Use it. clip-plate Instead of twists, and all the joints are carefully isolated. If you are planning to install a pneumonia signal, the list of tools will expand with pipe cutters and fittings for ducts.
Use copper tin terminals – they are less oxidized and provide better contact compared to conventional steel counterparts.
Connection scheme and electrical part
The most critical point of installation is the correct connection to the onboard network. The regular wiring going to the signal button on the steering wheel is not designed for direct connection of a powerful howler. Therefore, a mandatory element of the scheme becomes relay. It allows you to control a powerful consumer through a weak current of the standard button.
The principle of operation is simple: the current from the battery goes directly to the signal through the contacts of the relay, and the button on the steering wheel only provides a control impulse to the relay winding. This ensures stable operation and no voltage drop. Connection scheme It must be carefully collected, polarized, especially if you use signals with an electronic control unit.
Below is a table with the main parameters of the circuit elements for a standard 12-volt car:
| The chain element | Recommended wire cross-section | Nominal of safety | Type of relay |
|---|---|---|---|
| ABC power. | 2.5 - 4.0 mm2 | 15 - 20 A | 30 A (4 contacts) |
| Control (button) | 0.75 - 1.0 mm2 | 5 A (staff) | - |
| Exit the signal | 2.5 mm2 | 15 - 20 A | - |
| Massa (bodies) | 2.5 mm2 | - | - |
When assembling a scheme in the garage, it is convenient to use an mounting board or simply spread all the elements on the workbench for inspection. Make sure that 85 the relay is connected to the control wire (from the button), contact 86 - by the mass, 30 - plus the battery through the fuse, and contact 87 - on the signal itself.
☑️ Electrical circuit inspection
Under-bonnet installation process
After successful testing on the workbench, you can start installing in the underhood space. Choose a place for installation that will be protected from direct water flow when washing the engine and from excessive heating by the exhaust system. crone For the signal to be fastened, it must be rigid so that the vibration does not destroy the fasteners over time.
Laying wires carry out through the standard technological holes in the motor shield, using rubber bushings to protect the insulation from rubbing. Do not allow wires to sag near moving parts of the engine, such as belts and pulleys. Burning wires. It is best to pack in a corrugated tube for additional protection from oil and high temperatures.
If you install a pneumatic signal, the compressor should be placed in the driest place, and the receiver (if any) should be fixed horizontally. The ducts shall not have inflections which could obstruct the passage of air. After physical fixing of all elements, check again the reliability of all bolt connections.
⚠️ Attention: When drilling the body for the installation of brackets, be sure to treat the edges of the hole with an anti-corrosion composition to prevent the appearance of rust in the future.
Volume and tone adjustments
Many modern models of ship roars are equipped with a adjusting screw that allows you to change the tone of the sound. While in the garage, you can experiment with settings to find the most pleasant and effective sound. Adjustment is made by rotating the screw on the signal body when supplying power.
However, it is worth remembering that changing the tone can affect the overall volume. Too much screw twisting can cause the membrane to stop vibrating at the desired amplitude, and the sound will become quieter or disappear altogether. Set the optimal position of the screw with a counternut or a drop of paint so that the settings do not get lost from vibration.
It is also important to check the signal when the engine is running. At idle turns, the voltage in the network can be lower, which will affect the volume. If the signal is unstable, installation may be required. battery-power or a large-capacity capacitor to smooth out pulsations.
Why is the signal hoarse?
Wheezing can occur due to water entering the tube, weakening the attachment of the membrane or oxidation of contacts. Check the drainage hole at the bottom of the signal – it should not be clogged with dirt.
Legal aspects and safety of use
Installing an abnormal sound signal is not only a technical, but also a legal procedure. According to traffic rules, external light and sound devices must meet safety requirements. The use of signals simulating special vehicles (sirens, two-tonal horns) is strictly prohibited and entails administrative responsibility and confiscating the device.
Only single-ton signals with a certain frequency range are allowed. Even if your “ship roar” sounds beautiful, it should not exceed the set volume limits. The inspector may request that the device be dismantled if he considers its use dangerous or annoying.
- 🚫 Forbidden: installation of signals of special vehicles (blue / red light, howling).
- ✅ Permitted: installation of amplified civil type signals corresponding to GOST.
- ⚖️ Responsibility: fine for violation of the rules of operation of the vehicle or deprivation of rights when installing special signals.
Use a powerful signal only for its intended purpose - to warn about danger. Do not “signal” for fun or expression of discontent in traffic, it creates noise pollution and negatively affects the reputation of the driver. Driving culture more than the loudness of the beep.
The legality of the installation depends on the type of sound: single-ton signals are allowed, multi-tonal and special signals are prohibited.
Frequently Asked Questions (FAQ)
Can I connect a ship's roar directly to a button without a relay?
It's not recommended. The standard wiring and the signal button in the steering wheel are not designed for a current of more than 5 Amps. A powerful howler consumes 10-20 Amps, which will lead to overheating, melting of button contacts and possible fire of the wiring. The use of the unloading relay is mandatory.
Why did the signal become quieter after the installation?
The most likely cause is insufficient wire cross section or poor contact in the mass circuit. Also check the voltage at the battery terminals when the signal is on. If the voltage drops below 11 volts, the signal will not be able to operate at full power. You may need to charge the battery or replace the generator with a more powerful one.
How to protect the signal from water when washing the engine?
Set the signal down so that the water can flow freely. Many models have a special drainage hole – make sure it is not clogged. Additionally, you can use protective casings, but make sure that they do not block the output of sound and do not create resonance effects.
Will my battery power signal eat away?
The signal itself does not consume energy when not in use. However, if it is installed with errors (for example, a leakage of current through the relay), the battery can discharge in the parking lot. When installed correctly with a serviceable relay, the consumption in the off state is zero. Short-term horns will not harm a functioning battery.
