The current stage of development of car alarm systemscharacterized by the proliferation of multifunctional telematics complexes. From devices of previous generations, they are characterized by feedback, extensive remote control capabilities, monitoring functions for various machine performance indicators, and so on.
In this context, the Pandora DXL 3910position as an entry-level solution, in which not all are provided, but the basic means of a modern security-protective module. Again, the lack of individual options can be put into minus development only when compared with premium telematics alarms.
Owners of this kit are offeredthe possibility of controlling mechanical blockers, monitoring security devices using a smartphone, informing about temperature and fuel indicators, and the use of radio tags. This is the primary option for budget level alarms, but the developers have tried to get out of the category cut down by functions and offer a more advanced package.
As compensation for missing fundsGPS, in particular, the creators of car alarm Pandora DXL 3910 endowed it with more opportunities for interaction with the user through a proprietary application. Owners are available services in which you can configure the work of tracking tools online. A significant defect may seem to be the absence of a full-scale autostart for the engine in the main complex, but this problem is also solved optionally.
Like other telematic systems, the DXL package3910 includes a control unit (controller), an antenna-receiver and a set of sensors with protective mechanisms. The main unit of the system is mounted at the bottom of the control panel. The most successful is to install Pandora DXL 3910 in the very niche panels, but so that access to the unit remained for the construction of power grids. The antenna is installed as high as possible. If the interior design allows, then it is possible to integrate the device into the node of convergence of the roof and windshield. But the contacts of the receiver with metal elements and electrical appliances should be prevented.
Sensors and sensors should be placedin accordance with a predefined protection scheme. For example, impact sensors are mounted near the window surfaces. For temperature sensors, the placement point in the passenger compartment must be determined so that the heating equipment does not directly affect them. Triggers, stoppers and blockers, complementing the Pandora DXL 3910 kit, are placed directly in the protected areas. It can be locks of a cowl, doors, a luggage carrier, etc. It is important, that for these devices the scheme of electrotechnical wiring was in advance thought over.
Basic work on connecting componentssignaling among themselves and their introduction into the common electric network are carried out with the use of complete cables. The basic package includes the main and auxiliary wires, cables for each device, and a grounding device.
The central unit is connected to the battery on the12V, which will provide power to the system. Further, communication with the functional devices is carried out from the control module through the pin-outputs. For the convenience and reliability of the connection, the Pandora DXL 3910 system is provided with CAN bus support. With this module, which also connects to the central unit, you can conveniently monitor mechanical locking devices - access keys for the trunk, hood, doors, etc. The CAN bus can be configured either through the main control panel or by using a computer via USB-port) and the alarm management program.
To the strong points of exploitation of thisalarms, many include just an application for mobile devices from Pandora, due to which convenient control over all means of the complex is carried out. Even experts emphasize that the smartphone management scheme is more ergonomic even in comparison with key fobs.
What's more, the Pandora DXL 3910 has enoughreliable structural and element base. The owners note that the alarm system maintains its performance regardless of temperature fluctuations, the case can withstand small impacts and are not afraid of vibrations. But, of course, mechanical protection should still be present, as well as moisture-proof insulation, if the components are planned to be installed in places with a risk of water penetration.
Yet lovers of traditional solutions point tothe lack of a key fob, and adherents of modern technology products criticize the model for a truncated functional. Of course, the main disadvantage of the system is the lack of the ability to position and locate the machine directly through the navigation systems.
It has already been said that the complex is optionalallows the possibility of implementing autorun, but in this part it is worth waiting for a dirty trick from the Pandora DXL 3910. Feedback indicates that the optional introduction of the autorun engine with the help of the appropriate relay interchange does not always ensure the correct operation of the device. In addition, it is worth to prepare for problems with the immobilizer, which has traditionally become an obstacle for remote switching on the ignition. Solving this problem will help only one more addition in the form of a transponder with a key imitation.
On the one hand, the domestic car alarm systemhas a lot of flaws, which have to be solved by the users themselves during the installation and operation. But on the other hand, the developers left a lot of opportunities for the individual construction of the system for their own needs. In this there is a significant plus of the complex Pandora DXL 3910, the price of which, by the way, is also attractive - about 25-30 thousand rubles.
Of course, those who plan to contributeadjustments and new options, it is necessary to lay out not less than 5 thousand. But full telematics systems with basic autoplay support and advanced navigation capabilities are worth it even more.
