Get started
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.
When you install this car alarm system, make sure you do not
degrade, damage or compromise the safety of any system or device
in your vehicle.
Improper installation and wiring of the external siren may damage the
vehicle's electrical system, including vital vehicle computer and
operating systems. This could lead to an accident or cause property
damage and/or serious personal injury. It is highly recommended that
you seek professional installation advice from a qualified auto
electrician or, in the alternative, have the installation performed by a
qualified auto electrician.
Please make sure that the external siren is secured and mounted in
a location in which it will NOT obstruct any OEM vehicle safety
features. If an accident occurs and the external siren is fired as a
projectile, the manufacturer shall assume no responsibility for any
resulting bodily injury or vehicle damage.
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 your vehicle’s system type.
If you have no experience in installing electrical devices on vehicles,
you are not permitted to carry out the following work yourself. You
must have the assembly and connection carried out by qualified
specialists.
If connection is performed incorrectly, this may result in voltage high
enough to cause electrocution.

11
Install the external Siren
Before final installation, find a location in the engine compartment where
the siren will best be able to transmit the alarm sound to the outside
when the hood is closed.
Running the engine for more than 10 minutes presents a risk of burns.
Allow the engine and other parts in the engine compartment to cool
down for at least 30 minutes before commencing installation of the
external siren.
Loose connectors result in excessive voltage drop and may melt
insulation and cause wires to overheat, which can lead to electrical
fires. Reverse polarity connections (positive to negative) will blow the
fuse in the connection cable and may permanently damage the
external siren.
When 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 connect the connection cable to the battery so that the cable
passes in the vicinity of hot engine parts where the insulation can melt
and cause a short circuit or fire.
DO NOT connect the connection cable to the battery so that the cable
passes in the vicinity of moving parts where the cable can get caught
or entangled.
Ensure that the connection cable is coiled up and securely fastened
in the engine compartment with cable ties.
DO NOT touch the postive and negative terminals of the vehicle
battery at the same time. This can cause electrocution.

12
Securely connect the red wire to the positive terminal (“+”) of the battery.
Securely connect the black wire to the negative terminal (“-”) of the
battery. The external siren will make a brief alarm sound when it is
correctly connected to the vehicle’s battery.
Fix the siren by attaching it to non-movable parts and mount it in suitable
position.
