1.5. Access Card Features
Car alarm is equipped with access card reader and it is permanently armed. Each
access is verified by enquiry to access card presence. If no access card is detected
in the range within 20 seconds, the unit will launch silent alarm. Range of access
card reader is up to 10 meters. Usual time of successful detection of access card is
less than 5 seconds.
Buttons on ID card can active or deactivate card and put the reader into learning
mode. The cards are deactivated from production and must be activated before first
use.
Activation of card is done by pressing any button for 1 second. The LED on card
will blink two times.
Deactivation of card is done by pressing two buttons marked oo and o o for 1
second (both at the same time). LED on card will blink once.
Learning mode enables adding other ID cards into the system. Connect the reader
to 12 V power supply – and switch on the ignition key. Wait 10 seconds for
successful authorization of cooperating ID card to the system (card reader relay will
close, LED will stop blinking). Press the two buttons oo and o o on cooperating
card at the same time, hold them for about 8 seconds. LED on ID card must blink
quickly for 4 seconds. Within 10 seconds after this do the same operation on card
that should be added in the system (press the two buttons oo and o o at the same
time). The system can cooperate with up to four cards.
The access card contains two 3 V batteries CR 2025, one battery provides energy
for the card operation and the second battery is marked as “spare battery“ is for
replacement when the main battery runs flat. Battery life is approximately 6 months.
1.6. Emergency Button Features

3. Installation
3.1. Condition for Use, Safety

15
Prior to installation make sure that operation of mobile phones and also GSM
car alarm is not forbidden in the particular type of vehicle!
GSM Car Alarm is intended for installation in hidden, dry place inside the vehicle
cabin or storage compartment. Unit must be protected from water and other liquids.
Car Alarm GB 060 515C is intended for vehicles with 12 V power supply with
ground minus. Connection to +12 V must be protected by a 5 A safety fuse.
Disconnect the negative power supply pole of battery (be careful with car radio
codes).
It is recommended to install sensors first and then make connections to the unit.
Connect the newly installed cables to the original stacks.
For connections use only tools made for such connections. If such tools are not
available, use soldering.
Do not install GSM Car Alarm in places with increased level of disturbing
electromagnetic radiation, mainly close to antenna of radio transmitter.
Avoid installation in extremely hot places.
3.2. Connections Drawing

3.3. Hints for Installation
ED 001 002 - GSM antenna
Install on inside of windows or plastic places under dashboard. Fix with adhesive
tape.
Never stick to metal parts of vehicle body, do not place near alarm sensors - chance
of false alarms and near the cables and car radio – chance of interferences.
ED 002 002 - GPS antenna
Install horizontally under dashboard, under plastic cover of air inlet or in plastic
bumpers. Ensure the best possible view of the sky – the view cannot be covered by
metal objects. Be aware of glass coated with metal in windows – GPS signal doesn’t
go through them.
ED 060 600 - LED
Install in lower part of dashboard so the LED signalization does not disturb the
driver. Use 6 mm drill.
ED 060 601 - Emergency button
Install on lower side post on the driver side or under dashboard. Use 7 mm drill.
ED 060 605 - Alarm siren
Install in upper parts by the engine, point the output to the ground.
ED 060 620 - Wireless access card receiver
Bundle with cables near the car alarm unit.
ED 060 619 - Ultrasonic motion sensor
Install the transmitted and receiver on the side posts of windshield, install the unit
close to the car alarm unit.
Sensor is powered only when vehicle is armed so when ignition is on, the ultrasonic
signal is not transmitted into cabin.
Sensor can also be activated by air flow, e.g. when windows are open. Due to this, it
is not possible to use sensor in vehicles with automatic air conditioning.
ED 060 611 - Microwave motion sensor
Install in the middle of vehicle, in the tunnel between seats or on the ceiling. Set the
sensor sensitivity so it only detects a person entering the cabin.
ED 060 618 - Tilt sensor
Install in linear or cross direction close to the cabin floor.
ED 060 606 - Hood sensor
Install so the sensor trimmer is disconnected from the frame when hood is closed.

17
ED 060 250 - Microphone
Install to the side pole of windshield close to driver’s head. Do not install close to the
GSM antenna – to prevent interferences. After installation, set the microphone
sensitivity as described in table of SMS commands.
ED 060 260 - Loudspeaker with amplifier
Install near the car alarm unit. Set the volume to prevent acoustic coupling, the
procedure is described in table of SMS commands. Set the sensitivity so the
amplifier turns on only during phone call – not spontaneously.
CB 160 021 - RS 232 cable
Take out to a suitable place in vehicle cabin, preferably near the front passenger
seat. To connect a PDA, cable reduction CB 160 017 will be needed.
The unit is switched on by connecting external power supply. When the external
power supply is disconnected, the unit will be powered from internal backup battery.
During transport and storage, turn on the internal battery power supply by pressing
the INIT button on car alarm unit.
3.4. Checking Functionality
Start the car alarm unit as described in chapter “Quick start”.

on the car alarm unit.
Checking GPS
Send SMS message to the phone number of SIM card placed in the car alarm unit.
After installation or INIT of unit, it is recommended to take the vehicle to a place with
good view of sky, turn on the ignition and wait about 5 minutes to get valid GPS
data.
