System Installation and Wiring
These installation instructions do not apply to all types of vehicles.
They are meant only as a general guide due to the large number of
vehicle makes and models. Consult your local motor vehicle laws on
the use of this product to be sure it is permitted.
Through installation of this Car Alarm system, you should be sure as
to not degrade, damage or compromise the safety of any system or
device on your vehicle.
Improper installation and wiring of the external siren may damage the
vehicle's electrical system, including vital vehicle computer and
operating systems. That could lead to an accident or causing property
damage and/or serious personal injury. It is highly recommended to
seek professional installation advice from a qualifed auto electrician
or, in the alternative, to have the installation performed by a qualifed
auto electrician.
Please ensure that external siren is secured and mounted where it
would NOT obstruct any OEM vehicle safety features. In an event of
an accident, manufacturer is not responsible for bodily injury or
vehicle damage caused by the external siren being a projectile.
The manufacturer assumes no liability for damage caused to your
vehicle due to improper installation or use.
This unit is designed to operate on a 12V or 24V DC negative ground
electrical system. Connecting to other types of electrical systems will
cause damage to your vehicle. Please contact the manufacturer if you
are unaware of the system type in your vehicle.
If you have no experience in installing electrical devices on vehicles,
you are not allowed to carry out the following work yourself. Have the
assembly and connection carried out by qualified specialists.
Connecting incorrectly may result in voltage high enough to cause
electrocution

10
Install the external Siren
Before final installation, find a location in the engine compartment where
the siren has the best opportunity to transmit the alarm sound to the
outside when the hood is closed.
If the engine has been running for more than 10 minutes, there is a
risk of burns. Allow the engine and other parts in the engine
compartment to cool down for at least 30 minutes before starting to
install the external siren.
Loose connectors result in excessive voltage drop and may cause
over heated wires and melted insulation, which can lead to electrical
fires. Reverse polarity connections (positive to negative) will blow the
fuse in the connection cable and may permantly damage the external
siren.
Mounting the siren in the engine compartment make sure that the ties
are secured and the siren is not connected with movable parts. The
siren must be mounted with sufficient distance to rotating parts.
DO NOT lay the connection cable to the battery in such a way that it
runs past hot engine parts where the insulation can melt and cause a
short circuit or fire.
DO NOT lay the connection cable to the battery in such a way that it
runs past moving parts in which it can get caught.
Ensure that connection cable is coiled up and securely fastened in
the engine compartment with cable ties.
DO NOT touch postiv and negative terminal of the vehicle battery at
the same time. It may result to cause electrocution.

11
Securely connect red wire to Positive terminal (“+”) of the battery and
black wire to Negative terminal (“-”) of the battery. The external siren
makes a short alarm sound when it is connected correctly to the
vehicle’s battery.
Fix the siren with ties to non-movable parts and mount it in suitable
position.
Inserting Car Alarm to the cigartte lighter socket
After inserting the Car Alarm to the cigarette lighter socket the light will
be solid blue for charging. The device is ready for operation and can
receive the command from the remote control.
