INSTRUCTION FOR CAR ALARM INSTALLATION
GsmAlarm-420 can be installed in
all types of vehicles with petrol or diesel engines, 12V negative
earth batteries
(negative pole connected to vehicle frame). System must be installed in the passenger
compartment of vehicle according to the given instructions of installation.

Wiring diagram for vehicle protection
GsmAlarm-420 must be installed inside the vehicle passenger compartment in difficult access area.
Mount the device in place free from penetration of moisture and other corrosion - causing materials,
as far away as possible from heating elements in the passenger compartment and sources of
electromagnetic interference (vehicle computer, conditioner, block of relays). Avoid mounting
system unit directly onto metal parts of vehicle to prevent accumulation of condensate in the system
unit. Mount “GsmAlarm-420” in a way wire connectors are going from the bottom side of the unit.
Avoid placing wires adjacent to moving or hot parts of vehicle. Reserve 6V battery must be accurately
fixed close to “GsmAlarm-420” device. Use plastic fixing belts for fastening. Mount the battery in place
free from penetration of moisture and other corrosion - causing materials, as far away as possible
from heating elements in the passenger compartment. Operating voltage of battery must be 6 V,
system must operate in 6 V mode. Instructions for system reprogramming to vehicle mode described
in chapter 6.2.
Main power to GsmAlarm-420 is supplied (clamp „POWER“) from car battery through 1A standard
5x20 mm fuse, mounted in isolated block PTF/80A. Fuse must be mounted as close as possible to car
battery. Use heat (to +150 °C) and cold (to -60 °C) resistant isolated 0,56 mm² diameter red wire (SPEC
55) to connect „+“ to system power supply. Other system power supply clamp must be connected to car
frame “earth” in nearest most convenient point.
Connect inputs Z1-Z4 to relevant car contactors; input Z5 is used for system arming/disarming. All
outputs in the car mode are working in a zero-one mode; therefore no 2,2k
Ω
resistor loads are
needed.
6V battery supplies power to relay and siren (contact AUX).
