New generation car security system SHERIFF ZX-925 provides the highest degree of security due to the presence of six service channels with the ability to change the logic of their work.
There is also a pager with a TFT screen, anti-theft systems vehicle both active and passive types.

A pager (a two-way communication key fob with five buttons) allows the car owner to receive signals from him about the acceptance and execution of various commands. After each operation of the protective system, information about it is displayed on the key fob screen. Instructions are included with the delivery of the protective system.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

Initially, you need to decide on the installation location of the modules (for example, behind the dashboard of a car) and attach the head unit with screws. You can also attach any of the system modules using other fasteners, such as ties.

The main thing to say is that you should not install the security system in the same compartment with the power plant, in other words, under the hood, since the body of the head module of the security system is not airtight. Do not install alarms on various electrical components of the machine. They can emit a wide variety of radio interference, which can adversely affect the communication range between the head unit and the two-way transmitter.

Siren installation instructions

To install this module, find required space under the hood. The siren must be inaccessible, as well as its wires. It should not be accessible not from under the hood, not from under the wheel arches. There should not be any heating or moving mechanisms near the alarm horn. The siren itself must “look” down to drain water from it, and the horn horn must look from the engine. Thus, the siren signal will be as loud as possible. Fasten the module to the chosen place using screws using the special bracket.

Limit switch installation instructions

The end sensor, which is supplied with the system, is designed to protect such opening parts as the trunk (in hatchback and station wagon cars) or the engine hood. Be that as it may, this switch must be installed on a surface that is connected to the negative pole of the battery.

The limit switch must be placed where water does not drain or moisture does not accumulate. No need to put it under the fenders or luggage compartment drains. Install the circuit breaker in a location that is protected rubber seal. The limit switch can be mounted on the bracket included in the kit or on a 6 mm hole that you drill yourself in the right place.

The switch is installed in such a way that when the door, hood or trunk is closed, its movable contact is displaced by at least 6 mm, and, accordingly, when opened, it must be completely released.

LED indicator mounting instructions

The LED indicator is installed in the antenna module and consists of two parts. By LED indicator you can figure out what position you are in. protective system. It is also designed to warn and scare off potential criminals. The antenna module, and with it the indicator, is placed in such a place that it can be clearly seen both from the outside of the car and from the driver's seat.

Valet key

Install the Valet button where it will be most convenient to access it. It is best to hide the button, thus increasing the degree of security, and the actions of hijackers will be difficult. Valet key can be set to dashboard car or under it, directly next to the driver.

shock sensor

This sensor must be installed on a flat and solid surface that lies between the power plant compartment and the passenger compartment, on the passenger side. Attach the sensor with two self-tapping screws. You can also use cable ties.

Wherever you install the sensor, access to it must be free in order to adjust the potentiometer when setting up the system.

Instructions for connecting system wires

If you connect additional power relays to the head unit of the security system, make sure that there are damping diodes on their contacts. It is possible to interface the system with the relay only from the anode side of the damping diode. During the process of connecting and wiring, you need to pull out the system fuses. If there is no damping diode, the polarity of the connection does not matter.

Incorrect connection of the outputs of the power unit to high load circuits (trunk lock, doors, etc.) will damage the system.

The system is equipped with a manual shutdown function to ensure the highest degree protection. In some cases, for example, the key fob from the system is lost or damaged.

That's when you need to stop the security system manually. It is necessary to read the manual, namely the section “Manual arming of the system” or “Manual disabling of the security system”. The instruction contains all the necessary data.
