With all the abundance of different models of car alarms, choosing a truly successful model today is not so easy. It would seem that many car alarms meet such simple requirements as: auto start, the presence of a key fob pager, an anti-grabber and several functional modes, and a significant part of them are priced no more than $100-150. If you make a list of them, it will include a good dozen models from various manufacturers. But if you start studying them in practice, you will find that everything is not so rosy. Therefore, after careful sifting out of the indicated dozen, only 2 or 3 alarms will remain, and it is safe to say that among them there will be “double-sided alarms” of the Sheriff brand. In order to have a more or less complete understanding of all its products, it is enough to look at the review of the Sheriff ZX-755 car alarm, which is a solid mid-ranger and enjoys considerable popularity in the market.
Characteristics of the alarm Sheriff ZX-755
The success of the Sheriff ZX 755 car alarm mainly lies in the fact that it was initially created on the basis of a fairly successful software platform. This proprietary development of the alarm manufacturer Sheriff is so universal and thoughtful that at the moment the company’s engineers make all new models based on it, only eliminating minor shortcomings, adding new functionality and improving ergonomics.
And the Sheriff ZX-755 car alarm was also the result of such modernization. As already noted, it refers to car alarms with feedback. That is, the car owner has the opportunity to fully control its operation using a special keychain pager. It is equipped with a large display on which you can display information about the selected operating modes, current status, as well as diagnostic data for the communication channel and batteries.
The Sheriff ZX 755 alarm system and security functions are not deprived. In particular, it is capable of blocking engine operation in case of unauthorized access. It also has a special anti-robbery function, thanks to which the car alarm is triggered when an attempt is made to open the car door when the ignition is on.

Currently, among the feedback alarms belonging to the middle class, which fully ensure the solution of the tasks set to preserve safety, the “Sheriff” system has proven itself well, which, among other things, attracts motorists with a number of additional functions (for example , the presence of RFID locking and the ability to autostart), as well as an affordable price and ease of installation during installation.
Most car alarm systems offered on the modern market are accompanied by fairly detailed instructions, meanwhile, in each specific case, when dealing with the problem of how to connect a sheriff alarm, you have to take into account many quite important nuances.
The installation of any car alarm, as a rule, begins with choosing a location for the main control unit. Practice shows that it is most convenient for these purposes to use the compartment behind the glove compartment or the free space under the ventilation and heating control unit.
It is best to avoid attempting to install this unit in the engine compartment. Not only is there an increased risk of moisture and other aggressive liquids getting in there - there are many components in the engine compartment that can interfere with the radio signal, and this, in turn, leads to a decrease in the range of the system and creates conditions for false alarms.
The block is secured in the selected location with the supplied screws or using special braces. As for the engine compartment, it is much more appropriate to install a siren in it, and such a place should not be too accessible from the outside, remote from moving elements and protected from moisture.
When installing the hood limit switch, you should not forget that it must be fixed on a metal surface that is securely connected to the general “ground” of the car, while when pressing and closing the hood, the limit switch rod must move at least 6 mm, and when opening, it must rise completely.
It is best to mount the shock sensor on the hard surface of the jumper between the engine compartment and the passenger compartment (on the passenger compartment side).
The LED is placed so that it best suits its main purpose, that is, it warns a potential attacker as early as possible about the presence and enabled state of the security system.
The Valet button requires a particularly reverent attitude, which, after installation, must be both hidden from view and, at the same time, as accessible as possible to the driver
To connect individual components of the alarm system, you will have to do a certain amount of work in the cabin: make wire leads from the ignition switch (on which +12V voltage appears when the ignition is turned on), stretch the wires going into the cabin from the siren and the hood limit switch (and possibly the trunk ), make a reliable diversion from the nearest “mass”.
When installing such a system, you may have to cut the standard register for controlling the electric drives for controlling the door locks. As a rule, these wires are laid from the main locking (unlocking) switch to additional switches and then to the electric lock drives. For the normal functioning of the security system, the wire going to the main switch is connected to the green wire of the system, and the wire going to the electric drives is connected to the yellow one.
The car alarm connection diagram included in the kit provides complete information about the color masking of the wires and their connection locations. The only thing you should pay attention to is protecting the wires using special corrugated tubes and insulating tape, as well as securely fixing them with cable ties.

They expanded the functional range and improved ergonomic characteristics. The listed types of car alarms have a built-in autostart module, an effective transponder operating algorithm, and improved electronic mechanisms. Key fobs in some configurations are equipped with a liquid crystal screen, which displays information about the current state of the vehicle, as well as commands for remote control of the main subsystems of the vehicle.
What components does a Sheriff car alarm consist of?
The Sheriff brand alarm system, depending on the type, can be equipped with various elements. The common components of a car alarm are:
- Keychain;
- Control block;
- Digital relay;
- Dual zone shock sensor;
- Antenna;

The security line kit may include one or two key fobs that act as a transmitter. The control unit is mounted inside the vehicle.
Service and security options are controlled by pressing buttons on the key fob and interacting with the control unit. The alarm is turned off by pressing a combination of buttons on the electronic key, which must be known exclusively to the owner of the car.
Control commands are transmitted via a digital channel. This digital channel contains encoded information, usually dynamic. The vehicle is controlled using the key fob at a distance of no more than two kilometers. If an emergency situation occurs, the operation of the security line can be transferred to a reprogrammable channel (for example, arming or disarming a car, as well as controlling the main subsystems by using an additional radio channel). A digital relay allows you to remotely control the engine and ignition system. For example, in the event of a vehicle theft, the owner can block the ignition and engine systems, as well as the door locks, power windows and luggage compartment.

Advantages and disadvantages of using a Sheriff car alarm system
Today, among the purchased alarm systems, the Sheriff system is the most purchased. The main advantage of such a security system for cars is its low cost. The price for the set varies from 1000 to 4000 rubles. On the official websites of dealers of these products you can find a wide variety of reviews from users who purchased the Sheriff security system.
The video shows how the alarm works:
Another advantage of the Sheriff alarm system is the ability to install and configure the system yourself. The control key fob has a beautiful design and is easy to use, so almost all users like it. One of the main disadvantages of the described car alarm is the short range of the key fob. Based on the tests carried out, it was established that the maximum operating range of the control mechanism is 150 meters. Consumers also point out that the installation and operating instructions are not clear, which is why problematic situations often arise when performing installation and configuration work. Consumer reviews say that another significant drawback of the Sheriff security line is the frequency of false alarms of the system due to its poor interaction with the immobilizer.
It is known that when choosing a car alarm, the consumer must first decide on the functional set of the security system. Despite the fact that the Sheriff alarm system protects against theft and creates an appropriate level of vehicle security, it is important to remember: any alarm system can be opened by a code grabber if you have the necessary specialized equipment.

How are Sheriff car alarm components connected?
Installation of the complex begins with choosing the location of the main control unit. As a rule, it is installed in a hidden place (for example, behind the glove compartment or under the heating or ventilation control unit). Using the screws included in the kit, fastening is carried out in the indicated place.
It is better to install the siren in the engine compartment so that moisture does not get on it, and it is also invisible.
The limit switch is mounted on a metal surface. It is important to remember that the limit mechanism rod moves approximately 6 mm when closing/opening the hood. It is better to place the shock sensor on a hard surface on the passenger compartment side. The LED element is usually placed on the front panel so that it is visible.
All connecting wires are connected from the ignition switch with a voltage of 12 V. When connecting, polarity must be observed. The instructions supplied with the equipment contain a detailed description of the procedure for connecting connecting cable lines (by color). The kit also includes a general wiring diagram for the Sheriff alarm system for the car.
The final stage of installation work is to stretch the antenna wire to its entire length and secure it with fastening ties.
