Instructions for use with the alarm "Sheriff"
SHERIFF car alarms are equipped with operating and installation instructions, but not every car owner manages to independently connect the system. In such a situation, the optimal solution would be to contact a service center for qualified assistance. In addition, extended instructions for Sheriff alarms of different models can be downloaded on the Internet.
System connection
The car alarm control unit is recommended to be installed in free space under the air conditioning control unit or in a special compartment behind the glove compartment. It is extremely undesirable to place a control unit in the engine compartment, since there are a large number of parts that can degrade signal reception. Couplers or screws are supplied with which the unit is mounted in a selected location.
Siren, unlike the unit, experts advise installing it in the engine compartment. The hood switch is attached to a metal surface connected to the car body.
Between the engine compartment and the passenger compartment, on a small jumper from the passenger compartment, a shock sensor is located. The LED is mounted in such a way that it can be seen from outside the vehicle: in most cases, it acts as a kind of alert for attackers. The Valet service button is installed in an easily accessible place for the driver, but hidden for everyone else.
It is possible to connect certain components of the car alarm only after carrying out certain works: removing wiring from the hood switch, ignition switch and siren to the passenger compartment. There are frequent cases when cutting the standard wiring of door locks when connecting the Sheriff alarm system.
The best option is to contact specialists to install and configure a car alarm in a car service in order to avoid errors in the system and its breakdowns in the future.
Common faults
Despite the fact that Sheriff alarms are very popular, they also have their drawbacks. Buyers most often note the following problems in the system:
- Bad communication of the alarm with the key fob: the signal is fixed from the second or third time.
- The increased sensitivity of sensors.
- Trinket triggering only after a strong keystroke.
- Door lock does not work when the alarm is activated, or the lock does not close completely, which is why you have to close the doors yourself.
If there are problems in the system immediately after purchase and installation, the alarm can be exchanged in the store under warranty. In other cases, to eliminate the malfunction, it is necessary to contact specialists.
Advantages and disadvantages of signaling
Separately, it is worth noting such an advantage of the Sheriff car alarm system as affordable cost: it will be the best option for those drivers who have a limited budget. You can install it on both domestic and foreign cars.
However, the Sheriff system has its drawbacks:
- Wiring diagram. It is not recommended to place the alarm in the trunk or in the engine compartment of the car, since a large number of metal parts will create radio interference, which can lead to a system shutdown or poor communication between the key fob and the central control unit.
- Signaling vulnerability to code grabbers - special devices that read the system’s dynamic code. Sheriff, unfortunately, works on the basis of dynamic code.
- In case of defective parts of the system or discharged batteries, the car cannot be secured or the alarm itself disabled.
- To disable the armed mode, it is necessary to make considerable efforts when pressing the corresponding key fob.
If the key fob or other alarm elements is faulty, you can turn off the system by pressing the Valet key, which is located in a place easily accessible to the driver in the passenger compartment.
