The alarm is very useful and multifunctional. With its help, you can protect your car from thieves or accidental collisions in the parking lot. More complex security systems are capable of using a key fob to open the trunk from a distance, start the engine, or perform a host of other interesting functions.
Lada Granta models such as Norma and Standard do not have an anti-theft system in their factory equipment. The factory simply does not install them, since the designers considered this part superfluous, if you do not take the immobilizer into account.
That is why this article was created, since the relevance of the issue of installing an alarm system on the Lada Granta is soaring at exorbitant heights. Despite the fact that there is a huge range of security systems for cars on the market, they have almost identical installation schemes, with only minor differences.
Review of the standard central lock Grants
Before studying the principles of operation of the central lock, it is necessary to understand its composition. Such a system consists of the following elements:
- Central locking control unit.
- Door limit switches.
- Interior lighting.
- Actuators – horn and door locks.
- Remote control.
We will try to understand each element separately and analyze how the central locking on the Lada Granta works.
The principle of operation of the central locking system on Grant
The central link in this system is the control unit. It is he who processes all signals and issues “instructions” to actuators. The control unit sends impulses to the door locks and locks them.
Also, on command, it reverses the polarity on the locks and unlocks them. Limit switches are used to control the status of doors (open or closed).
The central locking unit needs this information to turn on the interior lighting and prevent the locks from locking with the door open to avoid damage to the drive or rods.
A remote control is used to control the central locking unit. It has three buttons:
- Opening.
- Closing.
- Opening the trunk.
To close the machine, you need to press “close”, to open it, press “open”. The trunk can be unlocked even if the car is armed.
To do this, hold down the button on the remote control for a few seconds - the trunk latch will be unlocked, and the trunk lid will not be taken into account. The lid must be closed within 30 seconds or an alarm will sound.
Any opening of the door while the system is armed is accompanied by a horn tone and the hazard warning light blinking. Thus, the car attracts attention in case of unauthorized access to the interior.
Additional features
It is worth noting that the system can be controlled not only using the remote control, but also the corresponding key on the driver's door. By pressing this key, you can lock or unlock all the doors of the car.
This is convenient in case of a sudden attack by intruders or to protect children.
The Central Lock Grants provide the ability to automatically lock the doors when the vehicle is moving.
To do this, this function must be activated:
- Start the engine.
- Press the open and close button for 5 seconds.
- A beep will sound under the dashboard as confirmation.
Now, when you reach a speed of 20-40 km/h, the car doors will lock automatically. This will eliminate the possibility of a child opening the door at speed.
Another possibility is power window control. If you hold down the door lock button on the remote control for 3 seconds, the central locking unit will raise all the windows in the car - very convenient if someone forgot to close their window and the ignition was already turned off.
The unlock button works the same way – it opens windows.
Installation
Installing an alarm system on a Lada Granta with your own hands consists of several stages:
- Removing the plastic steering column lining. Then the instrument panel is removed and the map mounted on the driver's door is removed. The parts are secured with screws and plastic plugs, which are removed with a special mounting spatula.
- The installation location of the main unit depends on the dimensions and characteristics of the product. Small modules of Starline or Pandora products are located behind the dashboard.
- Route the control diode to the front pillar trim on the driver's side. The antenna unit (in some assemblies contains an impact detection sensor) is glued to the top edge of the windshield. If the owner has previously installed the unit in a different location on the glass, it is recommended to replace the layer of double-sided tape that was glued to the module body at the factory.
- The siren sound signal is installed in the engine compartment, the cable is routed into the passenger compartment through standard channels received in the engine panel. Since overheating of the housing damages the electronics of the unit, the exhaust manifold provides protection from the sound signal. The base of the siren is fixed with screws that are screwed into pre-drilled holes.
- When installing an autostart alarm, it is necessary to install a sensor that measures the temperature of the cylinder block. The device is fixed with a nut according to the manufacturer’s recommendations; do not squeeze the element when installing.
Installation Rules
An alarm installation map (separate for each device model) is included with the factory installation instructions. During installation work, the elements are securely fastened with self-tapping screws or plastic clamps. When using double-sided tape, the adhesive layer may be destroyed due to temperature changes, loose parts may be damaged, and the vehicle's standard electrical wiring may also be destroyed.
