Highly functional alarm system Tomahawk mhz 868

Choosing a car alarm is an extremely important thing, because it is the security system that ensures the integrity of the car. However, when purchasing, it is advisable to pay attention to the availability of additional options that make operation easier. An excellent option would be the Tomahawk 868 mhz frequency alarm system, which provides high-quality security and has numerous functionality.

The list of system capabilities includes:

• an anti-scanner that protects the transmitted code from interception and an anti-grabber that makes hacking impossible;
• many security modes, including silent arming, the “Panic” function and others;
• “safe driving” option;
• delay of interior lighting;
• turbo timer, which increases the service life of the part;
• autostart, which provides remote engine start based on time or temperature;
• engine blocking function in case of theft “Anti-hijack”;
• Valet service mode, which disables some of the security functions for technical work;
• bypass of faulty zones, protection against fictitious system activations;
• remote analysis of the current state.

The kit includes all the parts necessary for correct installation and use of the system:

• processor unit responsible for processing and executing commands;
• antenna module that receives the signal from the key fob;
• main pager with LCD screen and feedback;
• additional keychain in case the main one is lost;
• sound siren installed in the engine compartment;

Ignition switch wire designations

Look at the diagram shown in the figure.
Terminal block with two starter contacts

The above does not mean that both cords can be connected together and connected using the circuits discussed here. The diagrams indicate one wire (ST1) that makes up the starter power circuit. This option is suitable:

• For all domestic cars without exception;
• For new foreign cars;
• For foreign cars up to 90-91 years of manufacture.

This is the paradox - the “ST2” cord is not provided in the new, as well as in the oldest models.

Diagram for TZ-9030

Here's how to connect the Tomahawk TZ-9030 main unit to the ignition switch to use autostart. Of course, after installation, you need to do programming, which is discussed below. If the use of a lineman is required, connect it to the terminal of the main alarm connector (black and red cord). The power connector, in turn, has the following wiring.

Instructions for equipment TZ-9030

If we talk about the Tomahawk TW-9010 model, the purpose of the IGN3 pin will be different from what is being considered here.

In "Chapter 1" the designations were listed: IGN1, IGN2, ACC, starter wire (ST). The “IGN3” cord has been added here, but it replaces the ACC wire. The “blue” cord coming out of the alarm terminal block must be connected to the ACC contact, otherwise the autostart will not work. At the same time, if you make changes to the settings, the IGN3 pin can be connected to the ST2 pin. True, it is not clear how to “emulate” the ACC wire then.

A “T” connection is used when connecting to all wires except the starter. And the “ST” cord needs to be cut to connect the resulting ends with the black and yellow wires. The cable that goes to the alarm from the lock is a signal cable (thin).

Diagram for TW-9010

A non-standard method of switching starter current is typical for the following alarm model: Tomahawk TW-9010. Voltage is supplied here from the 6-pin power terminal block when autostart is performed. The rest of the time, the starter wire conducts current, even if the car alarm does not work or does not work correctly. A blocking relay is included in the gap in the standard wiring. Whether it can be removed from the scheme is unknown. It is better, therefore, to stick to the recommended option.

Current loop without blocking

Note that the Tomahawk TW-9010 and TZ-9030 alarms can control the immobilizer bypass. The lineman’s “negative” cord is connected to the black-red cable (figure at the beginning of the chapter). The latter is designed to be connected to the “IGN3” pin, but in most cars this option is not used.

The ground potential on the black-red cord appears before the starter starts, which is exactly what is required for the lineman to work. In general, everything looks strange: in alarms with auto-start, they often provide a separate output intended only for connecting a lineman.

What to do if the key fob doesn't work?

Setting up the tomahawk 434mhz frequency alarm
Reasons why the alarm does not respond to button presses, as well as ways to eliminate them:

1. Incorrectly installed battery in the rear compartment. If the polarity is reversed, then the device will not need to be repaired - you just need to change the location of the battery.
2. The power supply in the communicator has run out. With this problem, the quality of the transmitted signal decreases and commands may be executed only once. Troubleshooting involves replacing the battery.
3. The internal components of the remote control are oxidized or clogged. The case of the communicator on the Tomahawk 9010 is water-permeable and not sealed, so moisture or dust can get inside. To fix the problem, you need to disassemble the remote control and clean it using cotton swabs or napkins. If this does not help, then you will need to test all contacts and connections on the circuit with a tester; all damaged elements must be re-soldered.
4. If the remote control is unstable after being dropped, you need to make sure that its case and internal parts are intact. As a result of an impact on Tomahawk 9010 key fobs, quartz is most often damaged. You will need to disassemble the device, visually verify the integrity of the board and test the communicator contacts with a multimeter. If the quartz is disconnected, then its contact joints must be re-soldered and glued to the circuit using thermal paste.
5. The remote control keys began to stick. If, after pressing the button, it does not return to its original position, then the “click” can be regarded by the control unit as prolonged. The problem is that the keys become dirty, so they need to be wiped externally with an alcohol solution or a toothbrush. In case of serious contamination, the housing is disassembled, and it would also be useful to ring the chain. If the button is damaged, it must be replaced with a new one.
6. A malfunction of the remote control may be due to electromagnetic interference in the area where the vehicle is located. This often happens near large industrial enterprises, security and military facilities, transformer substations, airports, etc.

Buttons and icons

To configure and control the model 9.7 complex, a main remote control equipped with a display and 5 keys is used. The screen displays icons that allow you to identify the triggered security zone. Additionally, there are icons displaying automatic start modes; there is a separate field for displaying time and temperature.

The kit includes a spare remote control with 4 keys and a control LED that allows you to monitor the activation of additional modes. The buttons on the key fobs are marked with pictograms; a description of the functions performed and possible key combinations are given in the alarm manual. The auxiliary key fob allows you to enable the same functions as the main device.

Factory reset for tomahawk tz 9010

The service manual presents all the nuances regarding setting up the communicator. Before carrying out the task, you must make sure that the key fob has working batteries installed.

Button meaning

Designation of indicators on the communicator

Description of the keys:

1. The button to activate and deactivate the protection mode is made in the form of a closed lock.
2. To automatically start the internal combustion engine and control this option, use a key with a key icon.
3. To control the trunk door lock, use a button with a trunk open indicator.
4. The key with the loudspeaker icon is used to activate or deactivate the silent protection mode.
5. Button for setting parameters and activating the backlight with the F icon.

To configure various commands, you may need to press the communicator buttons for a long time or with a short click. Keyboard shortcuts are also used for this purpose. All this information is specified in detail in the Tomahawk TW 9010 operating instructions. The alarm is configured using the main remote control, but an additional one can be used for control.

Setting up the key fob

Before performing the setup, you must bind the communicator to the microprocessor unit. Without this, adjusting parameters and controlling the anti-theft system will be impossible.

How to write a key fob into the memory of Tomahawk TW 9010?

When performing this task, all information about old communicators will be deleted from the microprocessor memory:

1. The key is installed in the ignition switch in On mode. There is no need to start the engine.
2. The Override service button is pressed until the siren plays four beeps.
3. The key is then released.
4. At the same time, on the communicator you need to click on the buttons for opening the luggage compartment and silent security. These buttons are pressed until a signal appears. If the main communicator is registered, the siren will sound once, the additional one - twice, the third - four times, etc.
5. Then you need to wait six seconds for the alarm to exit the binding mode. During this time, you cannot click on the key fob buttons or touch the key in the lock.

User Danil Andreev spoke about independently linking a new key fob to the Tomahawk 9010 alarm control unit.

How to configure features?

To adjust option parameters, you must use keyboard shortcuts:

1. Simultaneously clicking on the first and fifth buttons will activate the energy-saving function.
2. The fifth key is designed to activate and deactivate the backlight.
3. Clicking on the second and fifth buttons will allow you to change the notification mode for the car owner. In case of any events, the driver will be warned via vibration or sound signals.
4. If you hold down the key number 5, this will allow you to activate the clock, timer or alarm setting.
5. Pressing the fourth and fifth buttons, depending on the number, will activate the timer for a period of 10 to 120 minutes.

Setting with Override button

Some functions can be adjusted using the Override key:

1. The key is inserted into the lock and the ignition is activated.
2. The key is clicked six times. This will allow the car owner to enter the parameter programming mode.
3. Then the ignition is turned off. If the function is selected, the LED light will blink and the siren will play a sound signal six times.
4. Using the key, the option is changed by successive clicks.
5. To assign a specific parameter, all the communicator keys are used except the fifth. Each time you click the button, the siren will play a sound.

How to reset?

To reset all parameters to factory defaults, perform the following steps:

1. The car owner enters the programming mode in accordance with the described scheme. To do this, press the key 10 times.
2. The ignition is turned off. When the siren beeps, the button is clicked once.
3. Then the first key of the communicator is pressed.
4. The ignition is activated and switched off. If the settings are reset successfully, the alarm light will sound five times.

The Sher Tiger channel talked about resetting the settings of the Tomahawk anti-theft system on your own.

Automatic heating: instructions

In order to set the remote start parameters on the whitefish Tomahawk 868 MHz, you need to go to the programming menu.

1. Turn on the ignition and press the Override button six times.
2. Now turn off the ignition - the car beeps six times and the lights flash.
3. The Override key is pressed seven times (time interval) or ten times (setting the minimum temperature).
4. The button on the key fob assigns the desired value (lock - -5 degrees, open lock - -10, trunk - -20, siren - -30). For a time interval, the intervals are 1 hour, 2 hours, 4 and 24 respectively.

Model identification for Tomahawk one-way alarms

The old Tomahawk types CL-350 and CL-300 used the same key fobs, both came with the same ones - like most simple one-way alarms.

To accurately determine the brand and model of the Tomahawk alarm, you will still have to get to the central unit, if this is so important: the CL-500 has a built-in blocking relay, while the CL-350 has an external one connected. This is the difference between the two models

Developing this line, Tomahawk releases the CL-550, which is still on sale. Here the keychains are also the same, the design has become much more aggressive.

The latest car alarm in the one-way line is CL-700. Misunderstandings often arise here - after all, both key fobs (also identical) have a liquid crystal display!

People who have bought cars with installed systems immediately have a question: why doesn’t the feedback work? It shouldn’t - the information on the screen changes every time the corresponding button is pressed, but the key fob will not warn you about an alarm being triggered.

Advantages and disadvantages

Like any car alarm, the Tomahawk 868 mhz frequency system has its own pros and cons.

Advantages:

• high reliability in terms of resistance to hacking;
• wide functionality;
• trouble-free operation on proven firmware;
• possibility of self-installation;
• adequate cost.

Flaws:

• keychains made of fragile plastic - crack and break;
• the batteries in the remote control last about six months;
• lack of a mobile application;
• The support service is better than competitors.

Basic principles of installing a signaling system

Before installing a car alarm yourself, you need to read the instructions. The location must be chosen so that the module is not easily detected by a potential burglar or hijacker

It is important to avoid sources of heat and moisture. The antenna should be placed at the maximum possible distance from the vehicle electronics and alarm units

A step-by-step Tomahawk looks like this:

1. Turn off the onboard power.
2. The electronic control unit is placed in the cabin. The RF antenna must be high enough. Avoid contact with electrical wiring harnesses and metal objects.
3. We install the siren in the engine compartment with the horn facing down.
4. We protect high-current networks (dimensions, central locking, etc.) with fuse links.
5. We install the hood and trunk triggers in hard-to-reach places away from moisture.
6. The impact sensor should be located in the center of the vehicle.
7. It is advisable to solder the contacts in places where the ignition circuits are broken.

Installation of equipment in cars

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

Initially, the mhz electronic unit is installed in the car. It will be used to control the alarm in the future. The instructions for use show how to properly install the unit into the vehicle interior.

To ensure the highest quality signal reception by the antenna, it is installed as high as possible. In this case, its contact with metal is strictly prohibited.

The instructions for use state that the siren must be located in the engine compartment of the car. If an autonomous car alarm is used, it is installed in the service key.

The equipment is installed in such a way that the horn is at the bottom. To avoid oxidation of the device wiring, it is necessary to connect it inside the vehicle.

Main functionality

When each mode is turned on, a sound signal is heard. This option allows the vehicle owner to verify that the selected function is correct. When the protective unit is activated, the alarm responds with a short-term siren and flashing lights. If the option is connected correctly, the light sensor will start blinking. The system responds to the execution of the reverse procedure by sending identical signals.

The kit switches to immobilizer mode automatically thirty seconds after the ignition is turned off. The corresponding indicator lights up to confirm the selected option. To turn off this mode, you need to press the button with the image of a closed lock once.

The “Tomahawk 9010” series, with the help of which autostart is carried out remotely using a button with a key emblem, indicates the start of the mode by parking lights flashing three times, and the necessary indicators are displayed on the remote control monitor. After starting the power unit, the pager will signal with a specific melody sound.

Reviews

Mikhail, 31 years old:

“To be honest, I didn’t really delve into the analysis of models - Tomahawk was recommended to me by a fellow worker, so I installed it at the service center. The main points suit me - a normal price tag taking into account the installation, good signal range. Even in a metropolis, from the 20th floor you can easily reach around the yard. Convenient when you need to start the engine remotely. There were no problems except at the beginning, when I still didn’t know how to program functions. But now everything is fine, I definitely like this signal.”

Evgeniy, 24 years old:

“It’s funny, already on the first car I managed to set the alarm myself. Fortunately, the instruction manual was nearby. So everything went smoothly. It's been a couple of months now and no problems have arisen. In addition, it has everything you need - autostart, turbo timer, remote condition analysis. A very good option for your money, I advise those who have not yet decided to take a closer look.”

Connecting the trunk sensor

The next installation step is connecting the wire to the trunk sensor. We use a standard sensor. To hook up the sensor, we need to find the blue wire on the trunk lamp and solder to it the wire that will stretch along the left threshold.

Then you can start connecting the trunk opening and central locking control relay. To do this, you need to find the multiplex unit, it should be located on the back of the fuse box, behind the glove compartment, it looks like a small flat box. In order to get to it, you will need to remove the fuse box, do not forget to unhook all the connectors, as soon as they are unhooked, you can remove the block.

Now we turn it over and see the same multiplex unit we need, on which the central locking relay is located, as well as the remote trunk opening.

In order to remove the covers you need to unscrew four screws. In order to pull the multiplex out from there, you will need to halve the block.

Using a screwdriver, carefully pry off the latches and disconnect the block.

Problems with autostart Tomahawk

Since the autostart algorithms for alarm systems of this brand have changed little since the time of the Tomahawk TW-9010 (minor differences are due primarily to the introduction of support for Start-Stop systems), the information regarding this system can be applied to newer ones. On cars with a manual transmission, like other alarm systems with auto start, it will require the correct completion of the “software neutral” procedure. Moreover, here this procedure is set rigidly by the manufacturer and is not customizable by the user.

The soft neutral procedure includes:

1. Pull the handbrake with the engine running.
2. Press the autostart button on the key fob - after that, an indication of engine operation (a cloud near the exhaust pipe) will appear on its screen.
3. Remove the key from the ignition - if everything works correctly, the engine will not stall.
4. Get out of the car. When the door is closed, the engine will stop.

Compared to the common algorithm, where auto start is reserved immediately when the handbrake is pulled, this one is more complex. Often, users simply forget about the need for forced reservation with the button on the key fob or, on the contrary, do it before pulling out the handbrake.

In this regard, the automatic mode of the TW-9020 and TW-9030 is more convenient: you just need to pull the handbrake.

If, after correctly performing the backup in steps 1 and 2, the engine stalls and autostart does not work, then check the following:

• Does the alarm system “see” the handbrake being lifted? When it is pulled out and released, the corresponding indicator on the key fob screen lights up and goes out when the owner presses the button to check the alarm status.
• Does Tomahawk “see” the engine running? You need to know exactly how the alarm is connected. Monitoring engine operation by voltage (TW-9010) malfunctions when the generator malfunctions or the connection points of the power circuits are oxidized - in this case, the central unit will receive less voltage than is included in the algorithm as a sign of engine operation. When monitoring the oil pressure lamp, as a rule, there are no problems. If the alarm is configured to be monitored by a tacho signal, then try teaching the Tomahawk idle speed again, as described earlier.
• The last problem that can disrupt the operation of the program neutral is a malfunction of the driver's door switch. Without “seeing” the opening and closing of the door, the alarm will not complete the “program neutral”.

If “software neutral” completes normally, but startup attempts are not successful, pay attention to the following points. First of all, this is the starter cranking time, if the operation control is set by voltage or oil pressure lamp

In winter, when the cranking time is set to a minimum (0.8 s), the engine does not have time to catch, but the thickened oil already manages to extinguish the pressure lamp. The next time you try to start, the Tomahawk will “see” the engine running before the starter turns on, and will not make any further attempts to start.

Therefore, the optimal setting option for Tomahawk is control by tacho signal, with the starter cranking time set to maximum.

On cars with an immobilizer, check that the crawler is working correctly. To do this, just after turning off the ignition, simulate an exit by opening and closing the door, and then try to autostart by placing the key in the ignition. If the immobilizer is not “seen” by the crawler, then at that moment the standard key at the lock will “see”, and the start will occur without problems.

In the lineman, pay attention to the placement of the chip relative to the internal antenna (ensure maximum overlap of the chip antenna turns, it should be directed perpendicular to the turns), try changing the position of the response antenna relative to the transponder winding on the ignition switch. It’s worth finding an installation card for your car on the Internet - perhaps for the crawler to work correctly, it should be connected not with an overhead antenna, but in a break in the standard wiring

If the engine starts and immediately stalls, try increasing the crawler operating time in the alarm settings. On different cars, the immobilizer works differently and polls the chip both once after turning on the ignition, and periodically while the engine is running. If in this case the crawler is configured to turn on for a short time, then at the time of the second poll the immobilizer will no longer “see” the chip and will turn off the engine.

How to set up a Tomahawk 868 mhz key fob: button assignments

The Tomahawk security complex has several remote controls for controlling various functions. According to the instructions, the main thing for the 868 mhz dialog is a pager with an LCD screen and feedback. The transmitter has many indicator lights, as well as five main control buttons. The keys near the screen are responsible for opening and closing the central locking, arming and disarming. The end buttons help activate additional functions (each has its own icon).

In case of loss of the main remote control, a spare pager with similar functionality is provided. The main difference is the absence of a display, and the LED acts as an indicator. Also, the second remote control has a shorter signal range (up to 30 meters).

Trouble-shooting

Features of troubleshooting signaling problems:

When the anti-theft complex does not respond to commands, first of all you need to check the functionality of the battery. To replace the battery, you need to open the back cover of the remote control and remove the used battery, then click the F button on the remote control. A new battery is installed; polarity must be taken into account during installation. Then the lid of the device is closed and the button with the open trunk symbol on the pager is pressed. If these steps do not help, you need to check the condition of the board and buttons on the remote control. To do this, unscrew the bolts that secure the two parts of the case to each other and disassemble the device. If moisture gets inside the case, traces of it will be visible on the board, then the circuit must be dried. To do this, place it in a warm place, but not on the radiator. Do not dry the board near a household stove or under the influence of sunlight. Assess the condition of the contact elements on the diagram; if they are damaged or acidified, they need to be re-soldered or cleaned. Damaged communicator buttons must be replaced. The next stage will be diagnostics of the electrical circuits through which the alarm elements are connected. If they are damaged, broken, or have worn out insulation, signal transmission will be intermittent. Checking power lines is done using a multimeter

First of all, you need to pay attention to those sections of the wires that are located at the bends. If damaged electrical circuits are found, they must be replaced. Then all connections and connectors on the devices are checked

In particular, you need to check the electronic module and transceiver. If the installation conditions were not met when installing the antenna adapter, the quality of pulse data reception will be poor. Carefully inspect the condition of the connectors on the devices; if they have acidified contacts, they must be cleaned. If the siren turns on the alarm mode for no reason, you need to check the operation of the shock sensor. The device sensitivity setting may need to be adjusted. If the steps described above did not allow you to find the cause of the problem, you need to diagnose the electronic module. One of the reasons for its breakdown or incorrect operation may be moisture getting on the board. As with the communicator, diagnostics and drying of the circuit will be required. If there is no visible damage on the board, then the reason may be a software malfunction. Only high-quality diagnostics can determine the problem.

Functionality

Functions supported by Tomahawk 9.7:

• informing the owner about events using a remote control with feedback;
• automatic engine start (supports vehicles equipped with a start button);
• remembering the state when the power is turned off;
• protection of a car with a running engine;
• support for “anti-robbery” and “panic” modes;
• car security with sound and light signals in case of alarm;
• support for security mode without siren;
• built-in immobilizer;
• A 2-stage removal of protection is provided.

Main types of Tomahawk alarms

Let's look at the main types of Tomahawk car alarms and their descriptions. So, a Tomahawk alarm could be:

• one-sided;
• bilateral;
• double-sided with auto start.

Now more details about each type.

2.1. Unilateral

One way Tomahawk car alarms. These are ordinary security systems that do not include key fobs with feedback, designed for the simplest protection of your vehicle. As a rule, these devices have the letters CL in their names.

2.2. Double sided

Bilateral, or with feedback. A prominent representative of such a system was previously the Tomahawk TW 7010, which has long been discontinued. These alarms are equipped with a key fob with feedback. They can be either interactive or run on dynamic code.

2.3. Double sided with engine start

These systems, in addition to the key fob with feedback, have an autostart function on board, which allows you to start the car engine from a distance. Such alarms include Tomahawk TW 9010, Tomahawk TW 9020, etc.

Specifications

Before using the Tomahawk Frecuency 434 MHz car alarm, you need to familiarize yourself with its technical characteristics:

• the voltage required to power the security system is 12 volts;
• when the ignition is turned off, the alarm will consume 16 mA of current;
• the operating frequency of the system is 433.92 MHz;
• the operating range of the remote control in signal transmission and reception mode is up to 1.2 km;
• to power additional channels, the system requires 300 mA of current;
• the consumer can configure the system so that the response after sending the command is 0.8, 10 or 30 seconds.

How to set temperature trigger

Automatic engine warming up at a given temperature allows you to maintain the internal combustion engine in the always-ready mode. The option minimizes the time it takes to leave the parking lot and provides the necessary operating comfort.

To enable the procedure to be activated, an additional sensor is installed under the hood. Otherwise, the device will be guided by the readings of the thermometer inside the cabin, which greatly increases fuel consumption.

Ease of use is due to the ability to set the minimum temperature of the internal combustion engine, which activates automatic heating, and the limit value when the ignition is turned off.

The complete process of enabling the mode and setting parameters can be found in the corresponding section of the factory instructions.

How to check engine temperature

It is not possible to physically see the engine temperature on the Tomahawk TZ 9010 key fob - the option is not provided by the manufacturer. However, if the system is improved, this is possible.

1. Parallel installation of a temperature sensor on the front hood position limit switch. The procedure increases the risk of false alarms of the security system, so it is rarely practiced. The changing pulse misleads the processor unit, which the latter perceives as a hacking attempt.
2. Installation of the second element on the alarm antenna line. A more complex sequence that requires experience and knowledge.

To power the thermometer from the transmitter unit, a cable is connected to the second one (to the blue breaker). Then the wire is brought out under the hood and the sensor itself is attached to it. The sensor, in turn, is mounted on the cooling pipe or the internal combustion engine block.

To view, you need to hold down the key marked “open hood” and the temperature of the engine compartment will be displayed in the clock field.

Experienced car enthusiasts recommend installing additional resistance in front of the thermistor to regulate the autostart activation temperature.

Autorun doesn't work

Some netizens complain that the car does not start from autostart or that the engine warms up by the hour. These are the consequences of a violation of one of the Tomahawk X 5 alarm units or the mode activation technology. The source may also be the vehicle's on-board circuit. Usually, if the required sequence of actions is not included, the problem must be looked for in one of the indicated directions.

1. Battery drain. To remotely start a motor, a higher starting current is required than with a standard start. Usually the car makes two or three attempts and does not start, after which it sends a signal to the key fob. You can charge or change the battery.
2. Preliminary preparation was not performed correctly. Drivers often forget to put the car on the handbrake or take it out of gear.
3. Engine control is not programmed. There is a technical failure within the control unit itself. It can be solved by diagnosing the corresponding element or replacing it.
4. Contacts are coming off or terminals are oxidized. A common reason is when the car is parked in a damp box or on the street. To correct the situation, simply clean and crimp all connections.
5. Freezing of lubricants inside the crankcase compartments. Thick oil prevents the crankshaft and gearbox drives from turning. It is usually eliminated by setting a shorter relay response interval or increasing the antifreeze temperature at which the mode is activated. How to change the time for automatic heating can be found in the instructions.
6. Mechanical damage or exposure to large amounts of water. Consequence of unsuccessful car wash or repair. Solved by drying or replacing damaged parts.

Features of car alarms

Proper use of tomahawk equipment ensures that it performs all functions and protects the car from burglary. The car alarm can be operated without a key fob.

The exchange of information between systems such as the basic alarm unit and the liquid crystal key fob is ensured thanks to the presence of a radio channel. The alarm is characterized by:

• Efficiency;
• Durability;
• Durability.

The tomahawk 868 system features an innovative base unit and a new key fob that operates over a longer range than its predecessor.

Thanks to the presence of appropriate functions, the car owner can constantly monitor the operation of the equipment.

The liquid crystal screen of the tomahawk key fob is backlit, which allows a person to fully control its performance at any time of the day. When the need arises, a notification about a threat is sent to the key fob.
