Installation of alarms with feedback and autorun: features, recommendations, prices

Complicating the systems of automotive security also determined the trend towards segmentation of access control systems. On the one hand, the developers offer directly signaling packets in their classical representation, and on the other - telematic systems, through which the user can manage the pre-installed functionality. In the case of choosing a combined solution, the installation of signaling with feedback is performed taking into account a number of design and operational aspects. The car owner has more opportunities for flexible and optimized use of security tools without restrictions that may occur when adding an already installed alarm system with a new telematics system.

What is the difference between a system with autorun and feedback?

Autorun is a function that allows you to remotely or automatically turn on the engine. This feature is especially popular in cold regions, since it is directly coupled with the heating of the car. In addition, the control of the power unit as such provides effective control of the machine, warning and the risks of hijacking. In modern versions, car alarms with feedback of well-known brands like Pandora or StarLine suggest a preliminary agreement of this option with the tasks of a regular immobilizer, as it can become a hindrance to remote start of the car.

No less interesting and feedback signaling. It provides not only the exchange of commands with the user, but also the elements of a multitasking dialogue with the aim of more accurately adjusting the current status. And the exchange of messages is done on an encrypted channel, which excludes the possibility of third-party interference. To increase the reliability of the contact, the alarm system with feedback and autorun enables special conditions for placement and adjustment of the complete antenna. Through this receiver communication will be carried out. As a channel can be used and means of cellular communication, and a GPS navigation system.

Features of the installation

In contrast to the traditional signaling, the elements of the telematic security control also include the inclusion of additional components. It has already been said that for effective data transmission a special antenna is used, but sensors are also integrated. The set of detectors differs depending on the particular signaling package. But most often it includes impact sensors, temperature sensors, etc. Another feature that distinguishes the installation of signaling with feedback is the possibility of organizing a wireless infrastructure. The classical scheme of connection of components assumes the use of ordinary wiring, working, including with a side voltage of 12 V. Modern complexes, however, some of the components are connected by wireless synchronization. However, due to the shortcomings of this kind of connections, which are, among other things, instability, many manufacturers refuse radio signals and prefer reliable CAN interfaces.

Preparing for installation

Regardless of the method of connection, the main components of the alarm system will be powered by the power grid. Therefore, by the time of direct installation, it is important to prepare a battery pack with terminals and, in general, complete wiring. Separate attention should be given to the insulation of cables. There should be no open cores and damaged areas. All electrical equipment must be in optimal operating condition. Also, the installation of alarm with feedback and autostart requires that, if possible, the temperature and humidity conditions in the places of equipment and cable lines are observed. Therefore, additional work may be required on the insulation of the car's body.

Location of the central control unit

This is the main component, which is a small case with an internal microprocessor and connectors for connection. It is recommended to install it in a place disguised from prying eyes. For example, if an intruder decides to inspect the interior through glass, he should not be caught by the central block or other elements of the system. In accordance with the instruction, the installation of alarms with feedback must be carried out under the dashboard. If possible, it will not be superfluous to integrate this module directly behind its case, but so that there is no direct contact with other electronics of the car.

Installation of antenna, siren and sensors

The antenna will act as a signal receiver, so it should be placed closer to the outside, but within the cabin. It is best to place in the area of the rear or windshield. According to the instruction, the installation of signaling with feedback and, in particular, the receivers is carried out in a distance from the open metal elements. The method of installation is selected in accordance with the design features - using brackets, hardware or special fixatives.

The siren is located in the engine compartment. It must be immersed in the distance from the heat sources and the mouthpiece downwards, so that the water outside does not flow under the housing. As for the sensors, they are placed in accordance with the scheme, which assumes a specific kit. A typical alarm system with feedback by one's own hands is executed so that all points of physical access to the machine are covered - using the same fasteners, adhesive tape and construction adhesive, sensors can be fixed on the side window, in the engine compartment, at the doors, etc.

Connecting components

In most cases, the connection is realized via a three-pin connector, which is included in the basic configuration. The central controller, siren and antenna are connected to the battery pack. Further, a special relay can connect the control unit to other functional parts, among which sensors, salon microphone, siren, etc. Weakness of this scheme is considered a dependence on one battery. Therefore, experts recommend the introduction of an infrastructure and a backup battery, especially since the cost of installing a signaling system with feedback in this case will increase slightly - you can use a budget model from 2 to 5 thousand rubles. The main thing is that its capacity is not less than 7 A / h, and the voltage - 12 V. Then, through special connectors to the relay, the line from the backup battery is also fed.

Connecting the motor to the system

The power unit is provided with the input of the operation control, for which the red-blue cable usually answers. Direct control is realized either by the generator signal or by a tach signal. The circuit into which the cable is introduced must also serve a pulse signal that is proportional to the frequency of the engine speed. The wire will be connected to the generator, so the engine start commands must be monitored depending on the voltage output at the time of starting. At this stage, the scheme for bypassing the immobilizer with which modern car alarms are coupled with feedback should be provided. The installation of an electrical latch that will control the starting of the engine, in the same way, provides for the command of the starter. To ensure that there are no conflicts between this command and the locking immobilizer function, it is necessary to adjust the operating algorithms of both systems in software or in settings, without inconsistencies in the signals.

Manufacturers and prices

In addition to the above-mentioned Pandora and StarLine companies, Scher-Khan, Alligator, KGB manufacturers are also working on the development of multifunctional alarm systems. Under these brands, quality and at the same time inexpensive signaling with feedback comes out. The prices, installation and a set of functions are usually interconnected - together with installation and a typical set of possibilities the average complete set can cost about 15-20 thousand.

Premium models with telematics control offer more options. For example, the functional in this case can be supplemented with advanced navigation system tools. Location determination and tracking counters are only a fraction of the options offered by such feedback signaling. Prices, the installation with its nuances and the presence of new opportunities in this case also affect each other as factors - premium kits will cost about 30-40 thousand.

Conclusion

With all the advantages of signaling systems controlled by security and telematics systems, they have one significant drawback - technical and functional complexity. At the same time, how effective the system will be in the course of operation, this depends on the quality of installation and basic settings. Therefore, experienced owners recommend to immediately trust these events to professionals. How much does it cost to install a signaling system with feedback in a specialized service - this is an ambiguous question, but the installation of entry-level kits by average standards costs 5-8 thousand. Is it economical to make a complete installation yourself? Also the issue of individual opportunities. But the fact that most car alarm manufacturers are developing components in such a way that it is physically impossible to perform an incorrect connection is also in favor of an independent installation.
