Alarm Sheriff 5BTX900LCD (ZX-900)

The security system manufactured under the Sheriff ZX 900 brand does not have an auto-start option. However, the design of this system initially contains elements with which it is easy to implement a turbo timer. Moreover, such a timer will be compatible with any ignition switch, regardless of the number of lines switched by it. Along the way, it will be possible to block one or more power circuits, as well as connect an alarm transmitter. How to achieve all this is discussed further.

ZX-900

Installation and Use Guide.

The system has six independent (two of them are remotely controlled) functionally reprogrammable channels.
These are six physical wire lines with programmable operating logic, providing flexible changes in system functions for controlling the shutdown of turbocharged engines (turbo timer), searching for a car in a parking lot, remotely turning off the system siren in the “NIGHT” mode with a control channel for an additional pager or mobile communication device, security service a car with the engine running without an ignition key, control of additional devices at specified time intervals. The interactive pager provides real reception of signals confirming the execution of a command by the system. During one security cycle, the system provides information about each triggered sensor on the LCD display of the two-way communication key fob.

To ensure the highest level of protection for your vehicle, this security system has a programmable manual override feature. In some cases, for example, when the system's remote control key fob transmitter is lost or does not work (or perhaps your key fob transmitter is blocked by powerful radio emissions from a jammer-type device), you may need to manually arm or manually disarm the system. Read the sections “Manually arming the system” and “Manually disabling the security system,” which detail the procedures for arming and disarming the system in such a situation. In addition, this manual contains a table in one section of which the system functions are used, including the selected system shutdown method, and the optional equipment installed in the vehicle. Although the Secret Code function is not programmed by default (you must enter a personal code to disable the system), the Valet switch can also be selected to disable the system. See which method was programmed to shut down your system and review it in the appropriate section of this manual.

If the F13 “Secret Code” function is programmed, then writing codes for new key fobs, changing the secret code, changing the status of programmed functions from F12 to F27, emergency disarming of the system, turning off the system when triggered in Anti-Hi-Jack modes are possible only after entering the secret code! Changing the parameters of functions F1 to F11 does not require entering a secret code and is always available.

Transmitters with technology to protect digital codes from interception (Keeloq)

The key fob transmitters included with this security system use the most advanced and reliable form of radio frequency transmission of any car security system currently available. Some of today's sophisticated car thieves use devices known as code grabbers, which allow them to receive and store the signal sent by the car's remote control device. After the driver leaves, this code is used by the thief to disarm the system.

Unlike the remote control devices described above, the key fob transmitters included with your security system change the code of the transmitted signal every time the button is pressed, so when a thief plays the intercepted signal from your key fob transmitter, the security system simply will not respond to it. If the button on your transmitter key fob is pressed more than 30 times when it is outside the control of the security system (for example, children are playing with it), the system will not respond to the call from the transmitter key fob when you decide to use it again. You need to synchronize your key fob transmitter with the security system receiver. To do this, simply press the system arming/disarming button on the transmitter key fob twice within one second. After this, the system will again respond to all remote control commands.

Types and characteristics of models

Let's look at the most popular models of anti-theft systems among consumers:

Sheriff with automatic start. The main feature of this anti-theft system is the ability to automatically start the car’s power unit remotely. This function is especially convenient in winter, since the driver can warm up the engine and interior of the car in advance, while at home. The “alarm” kit includes a key fob with two-way communication, which allows you to monitor the condition of the car. The cost of such anti-theft systems will be from 5 thousand rubles and more.
Anti-theft installation Sheriff with feedback. The central processor installed in the car exchanges data with the control panel via a secure channel. As a result, the car owner will always know the condition of the car. All data on protection and impact on the body are displayed on the remote control screen. The cost of models with two-way communication averages from three thousand rubles.
The APS-2500 model should be highlighted separately. This is a multifunctional security system equipped with a two-level sensitivity controller. It is possible to connect an additional sensor and channels for data transmission. If it is necessary to perform an emergency shutdown or activate the anti-theft system while the power unit is operating, you can use a PIN code. You can find this model on the market for 1800 rubles.
Model ZX-750. Another alarm system with two-way communication. The main feature is that the maximum range of operation between the control module and the remote control is up to two kilometers. The anti-theft installation can monitor the operation of the light alarm. The average cost is from 4,500 rubles. The price may vary depending on the store and region where the alarm is purchased.
BTX 5900LCD. This model belongs to the premium segment of the market and is positioned by the manufacturer as a business class alarm system. It has extensive functionality; you can configure remote engine start and automatic switching on of lights in the car interior. The average cost of the system is 6 thousand rubles.
TX-35PRO. The system is equipped with a two-channel receiver, as well as a two-level shock controller. You can configure the device to work with four remote controls. The price of this alarm model is from 3 thousand rubles on average.
APS-2600. The system belongs to the budget segment of the market, its average cost is about two thousand rubles. The alarm has no feedback; the kit includes two key fobs without a display. However, this alarm model allows you to effectively protect your car from burglary thanks to the included immobilizer, as well as a two-level shock sensor.
The APS95LCD alarm has a feedback function. Signals are transmitted between the system and the remote control via a secure channel, which eliminates the possibility of impulses being intercepted by intruders. The shock controller can be adjusted to reduce or increase sensitivity. The presence of “Panic” and “Anti-grabber” modes allows you to ensure reliable system protection. The car owner can independently reprogram the anti-theft system. It is possible to automatically start the engine. This “alarm” differs from its predecessors in the design of the remote control. The cost of the alarm system is from 3 thousand rubles.
Sheriff ZX-1070. This model of anti-theft installation is considered one of the most budget options. The package includes an upgraded remote control, and if necessary, you can configure the start of the power unit remotely. One of the varieties of this system is the Sheriff ZX-925 model. The fundamental difference is the presence of a special code intended for emergency unlocking of the system. The average cost of a car alarm is 2,500 rubles.
ZX-900. The system is recognized as the most successful modification among the entire model range. Some market experts classify this “alarm” as a premium segment due to the large number of useful functions and capabilities.

How to install

The instructions for the ZX-900 recommend adhering to the following installation sequence:

Unpack the alarm, connect the components, and then apply power from the car battery for a preliminary test of functionality.
Install the processor unit in the cabin, ensuring good fastening to the structural elements.
Place switches under the trunk or hood lid that determine the position of the elements.
Screw the sound alarm to the engine bulkhead (it is permissible to use a product with an autonomous power source).
Stick the antenna unit onto the upper edge of the windshield.
Lay the cable and secure the hidden switch. The unit is located in a quick access area from the driver's seat.
Screw the shock sensor to the engine shield on the passenger side of the car. Provide unobstructed access to the part to adjust sensitivity.
Connect the elements with the wiring harnesses supplied by the manufacturer. The connection is made in accordance with the diagrams from the documentation. The alarm system is equipped with a built-in controller that implements the central locking function.

How to remove the body of the Sheriff 5btx925lcd key fob

To disassemble the key fob you will need: a small Phillips screwdriver, a small napkin, a knife or a thin plate. To remove the remote control housing, follow the instructions.

Turn the keychain back towards you.
Open the battery compartment cover. Remove the battery.
There is a self-tapping screw in the battery niche. Unscrew it.
Using a knife or narrow plate, pry the body in the middle.
Carefully separate the pager into two parts.
After the work has been completed, assemble the key fob in reverse order.

User manual

The control unit of the Sheriff ZX-900 equipment is programmed based on the tables given in the operating instructions. When shipped from the factory, the setting is entered by alternating the use of the ignition and pressing the hidden Valet switch. The driver or installer can program a separate function that requires a 2-digit numeric password. The setup method and input algorithm are described in detail in the car alarm user manual.

After entering the menu, you must select the required section (by pressing the Valet button). To adjust the current value, use the button with the locked padlock symbol located on the 5BTX900LCD communicator. The adjuster performs from 1 to 5 clicks, selecting the required value from the table. After programming, it is recommended to test the operation of the complex and make adjustments (if any failures are detected).

A communicator or backup transmitter is used to control security and additional functions. The display of the main console schematically displays the state of the security zones when the protection is turned on; a separate field is allocated to display the current time. Since the screen is unified for several modifications of Sheriff alarms, some of the icons are not used.

If the remote control is lost, the driver turns on the vehicle security by pressing the Valet switch for 3 seconds. After the beep, the control diode turns on (in rapid flashing mode), which indicates that the door switches or trunk lid are waiting to close. After closing the last door, the car is armed; a regular car key is not required.

The alarm system supports an additional transponder, which is previously stored in the memory of the head unit. Additionally, adjustments must be made to the ZX-900 equipment settings. After activating the mixture ignition circuits, the search begins for a device that must be stored with the communicator. If the device is detected, the engine start circuit interlock is disabled. If the transponder is not detected, protection of the ignition and starter circuits is activated.

Why is it not programmable?

It is not always possible to program the remote control key fob Sheriff 940, 2500, 4BTX940LCD, APS95LCD B4, etc. This occurs due to incorrect operation of the system:

the remote control is faulty;
the alarm is constantly in the “Valet” mode, as evidenced by the red LED;
damage to the electrical circuit running from the button to the control unit;
The system does not recognize the “Ignition on” command. In this case, contact the service center immediately.

While the alarm is in the Valet state, all security systems are turned off, except for remote control of the “Panic” mode and unlocking the door locks.

Deactivate the security system from the key fob button or Valet key, you can also do this by entering your personal code. Turn on and then turn off the ignition system. Within five seconds, press and throw the Valet key. The LED on the panel will turn on continuously. The system switched to Valet mode.

Turning off Valet mode

Turn the ignition system on and then off.
Within five seconds, press the Valet key.
The LED on the panel will go off.
The system returns to normal mode.

Alarm systems "Sheriff" have a high-quality service base, their repair will not cause difficulties for specialists, and the extensive service network will not force you to send a spare part or go to another city. Expert technicians will carry out repairs, check compatibility and quickly fix the problem. Sheriff systems are very reliable and most often repairs are simply not necessary.

The American Sheriff alarm system will reliably protect your vehicle from theft and other criminal attacks. An expanded set of functions will make driving more comfortable. The main drawback is the range of the main communicator, which in practice turns out to be less than stated.

Transmitters

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"

Transmitters are equipped with a technology to ensure the security of digital codes from interception attempts (Keeloq)

The key fob that the sheriff zx 900 is equipped with has the most highly protected radio channel. Many car thieves use a signal memory system that transmits a signal to the car's key fob and records it. When the driver leaves, the burglars send a code to the car and steal it. More information about this can be found in the instructions for the device.

Sheriff zx 910 works according to an algorithm that constantly changes the code. Even if the villains record the signal, the car will not respond to it. If the button on the sheriff zx 900 key fob is pressed more than thirty times (for example, children are playing with the key fob), out of sight of the car, then when you try to open the car, the transmitter will not work. In order for it to work again, it needs to be synchronized with the security system.

Protection measures

There may be an opinion that there is no protection from this device. But that's not true. It is enough to equip the car with an alarm system with dialogue encoding and the ability to turn off the standard radio channel. These requirements are met by almost all modern security devices from leading domestic manufacturers Pandora and StarLine.

Hijackers have never managed to intercept the control code of these alarms.

And you can install them in any Autostudio service. Just call and make an appointment.

Instructions for manually arming the system

If it is not possible to use the sheriff 5btx900lcd key fob, use the Valet button, it will help even if you do not have a car key.

Instructions for fully arming the vehicle:

press briefly, quit, and then press and hold (more than 3 seconds) the VALET key until you hear a signal that the car has turned on the alarm;
the LED will flash, signaling the closing of the last door;
after closing the door, after three seconds the full security mode will turn on;

If there is a duplicate closing chain for the doors, and with program function F27 active (when the security system is turned on, then, according to the instructions, all doors are locked automatically), they are closed accordingly. Arming in manual mode is performed once, until the security system is turned off.

Note: if the ignition is turned off, manual arming is only possible after a pause of 5 seconds.

Autostart at time intervals or at specified temperature

If you want to configure the engine to start at certain time intervals, you need to:

Press F twice;
Go to the indicator flashing mode;
After you click on the same button again, only the selected indicator will remain;
The frequency of its flickering indicates a previously established cycle:

No blinking indicates that the function is disabled;
Uniform flashing – the cycle lasts an hour;
Two flashes and a pause - a two-hour cycle;
Three flashes and a pause - four hours;
Four flashes and a pause - twelve hours is set.

Anti-Hi-Jack, etc.

Hidden capabilities of the "900th Sheriff"

Turbo timer option and “Sheriff” signaling

As stated in the instructions provided by the manufacturer, you first need to determine where contact “15/1” is located in the car. It is this contact that receives voltage when the ignition is turned on, as well as when the starter is started. The “IGN1” cord coming from the main signal connector is connected to contact “15/1”. And then, if a turbo timer will be used, connect the “IGN2” cord:

Scheme with implemented “turbo timer” option

The switching relay, controlled by one of the programmable outputs, will close for 3 minutes (option F1). The relay coil is connected to the Disarm output, but channel CH6 can also be used.

Now see what the instructions say about programming the following two pins: CH5, Disarm. Only the second of them can control the relay, the contacts of which duplicate the turbo timer:

Alarm programming table

Channel CH6 is also provided to implement the timer. This means that it is better to leave the default values. If required, you can connect a blocking relay to the Disarm output, and a pager (alarm transmitter) is connected to wire CH5.

Basic connection diagram

The instructions supplied with the Sheriff equipment of the model in question provide a diagram:

Shown here are two latching relays: one using normally open (NO) contacts, the other using normally closed contacts. Perhaps this amount of blocking is unnecessary. But once you connect as the instructions recommend, you won’t have to program anything. The Sheriff 5btx900lcd alarm system, also known as “ZX 900”, is initially configured for the cable connection option indicated above.

To implement a turbo timer, you will need one relay, the power contacts of which can be connected to the ignition circuit. Moreover, we are talking only about the use of normally open contacts (30 and 87). This relay can be controlled by one of the following outputs:

Programmable channel designated as CH6 (options F24 set to 2);
Blocking output of the Sheriff ZX 900 signaling, controlling a “normally open relay” (option F22 should receive the value 2).

According to the instructions, the first option is recommended. What is better and how to connect additional equipment to the Sheriff signaling is discussed further.

Button search pattern

If a button is not found in these areas, then you need to carefully look behind the fuse hatches.
Sometimes it is located behind the glove box. The main rule during the search is not to be nervous. During binding, the alarm beeps and the car owner feels discomfort. It is not for nothing that it is said that in any situation one must include the method of deduction. In this case, you have to act like a car thief, so you need to think about what a person would do at this moment.

When the button is found, all that remains is to do everything according to the instructions.

When the key fob is attached, you can safely use it and leave the car in the parking lot.

Selecting the optimal option, programming

Let's turn to the instructions and look at the diagram, which shows what exactly the contacts of the additional relay should close:

The Sheriff ZX 900 signaling system has a turbo timer initially. The duration of its operation is regulated by option F1. Wires IGN1 and IGN2, shown in the diagram, must be included in the car's ignition wire. The IGN1 cord, when connected to a standard lock, is connected to terminal “15” (not shown in the diagram). It turns out that it remains to consider what the winding of your relay should be connected to. Which is done in the next chapter.

Connecting the turbo timer relay coil

Let's say you have a 30 amp normally open relay and need to implement a turbo timer. Then, when choosing a control output to connect the relay coil, follow the algorithm:

If both a pager and a lock are used, one channel can control the behavior of the turbo timer relay - CH6 (set option F24);
If blocking is not needed, it is better to connect the winding to a black wire with a white stripe (program option F22);
Even when using blocking, you can do as indicated in point “2”, but then the blocking relay is connected to the “gray” wire (CH5).

Note that the Sheriff 5btx900lcd alarm system is initially configured as follows: output CH5 must control another blocking relay (N.R.). To control the pager, configure option F22.

The wiring diagrams for the winding contacts look simple:

These diagrams are not included in the instructions, but they are generally accepted. Everything that applies to electrical equipment is also true for Sheriff signals. Use the circuits by installing any low-current diode. The voltage value on it does not exceed 16 Volts.

When installing or switching any wires in the car, be sure to disconnect the negative terminal of the battery. This advice is also well known.

Signal programming

Having opened the instructions, you can immediately find a table of programmable options:

If function F13 is still assigned the value “code”, programming the Sheriff ZX 900 system is done as follows:

You need to disable the security mode and turn on the ignition;
The Valet button is pressed a certain number of times equal to the first digit of the code;
The ignition is turned off and on again;
Repeat “step 2” for the second value;
The ignition is turned off and on, then proceed to “step 3” from the previous sequence.

Pay attention to the important options: duration of the turbo timer (F1), assignment of the INST2 input (F16) and everything that is indicated in the text. It is clear that service functions are indicated by numbers whose value exceeds “13”. And everything that is less than 13 is user options, and nothing more.

Note that by turning off the ignition, the owner can interrupt the operation of the turbo timer at any time. To do this, press the “3” key on the key fob twice.

Programming a new key fob pager

If you intend to record the code of the anti-robbery transponder, then turn off its power before starting any action. In order to attach the key fob to the alarm control unit, disarm the car using a command from the remote control or by entering the code using the “Valet” button. When using a secret password, the pager is linked using the following algorithm.

Turn the ignition on and off. Turn it on again.
By pressing the “Valet” key, enter the first digit of the personal code (the number of presses is the first value of the password).
Turn the ignition off and on.
Using the "Jack" key, enter the second code value.
Deactivate and activate the ignition. A beep will follow.
Click "Jack" three times. There will be one long beep of the siren.
Press the 1st button of the first switch. A squeak will follow.
Repeat the previous step for the remaining remote controls.
Turn on the transponder. A siren will sound indicating successful actions. Turn off your device.
To exit programming mode, turn off the ignition or do nothing for eight seconds. One short and one long beep will sound. The LED indicator will turn off.
Check the transponder.

Possible problems and their solutions

If the equipment does not respond to the key fob, then you need to check the condition of the battery. The cause of the defect may be destruction of the key mechanisms or failure of the communicator controller due to moisture. To determine the cause of the breakdown, you need to disassemble the device; in case of irreversible damage, you will need to purchase a new remote control.

To disassemble the communicator, you need to remove the battery and then unscrew the small screw hidden in the depths of the niche. To separate the halves of the body, a plastic plate is used, which is inserted into the middle part of the device

Then you need to carefully unfasten the latches located around the perimeter of the case. The removed elements are washed with alcohol, damaged components are replaced independently or in the conditions of a service that repairs electronics.

If the receivers and transmitters located in the remote control and the car are out of sync, you need to re-enter the device code. To enter the setup mode, triple-click the programming switch (with the ignition on). After sound and light alarms are given, the security button is pressed, after entering the code into memory, a siren signal is given and the control diode on the transmitting unit turns on. The remaining remote controls are entered in the same way; no more than 5 seconds should pass between steps.

Incorrect operation of the security system is observed when the switching harnesses or system components are damaged. Cable testing is carried out with a test device, damaged sections must be replaced. Determination of the causes of malfunction of electronic units is carried out at a service center. Since alarm production has been discontinued, if the processor module or transceiver fails, a new security system will have to be installed.
