7. Product Description
The car alarm system can be used to monitor a vehicle. The primary task is not in frightening
the thief away via the speaker but via live transmission of an alarm message to up to 6 phone
numbers by text message.
If the sensors and external electronics (connected to the switching inputs) recognise any
impermissible interaction, various actions like alarm via text message or switching consumers
may be triggered.
The customer may at any time perform other actions by sending text message from his mobile
phone, e.g. determine the current GPS position (coordination or web link), request the status,
switch the relay, check the switching inputs or perform a „silent call“ to hear what is currently
taking place inside the vehicle.
The microphone or speaker can be used to accept calls and call pre-set phone numbers.
Many transverse functions (switching relays when deactivating the alarm, the call causes an
answering text message with the current GPS position, etc) can be used by the customer to
configure the product as desired.
The GPS receiver is used to determine and monitor GPS zones (Area, GeoFence), i.e. places
where the product may be present.
The USB-interface, which is not mandatory for operation or configuration can be used by the
customer for firmware updates to receive further functions.
The product is secured against manipulation with an internal battery.

8.2 Description of the Connections
GSM status LED (1):
This LED shows the current GSM status. For this, the LED has the following presentation
options:
• LED is lit green: Searching for GSM network
• LED flashes green (every 1 s): Device registered in the network
• LED flashes green (every 1/2 s): Call / phone connection
• LED flashes red: No network connection / PIN error / invalid SIM card / PUK / …
• LED off: No power supply present / device defective if voltage supply and SIM card are
present
Battery status LED (2):
The internal battery is charged and managed via a separate hardware. Thus, the battery can
also be charged when no SIM card is inserted and the entire GSM hardware is deactivated.
It is unimportant of whether the battery is charged via the external voltage supply (on-board
voltage) or via USB.
This LED provides the following information:
• LED is lit red: The battery is being charged
• LED is lit green: The battery is charged
• LED is lit red and green: An error was recognised (e.g. no battery present)
• LED off: No external voltage supply present
GPS status LED (3):
This LED is used to recognise the activity and status of the external GPS receiver.
The following display options are available for this:
• LED flashes blue: Current GPS position determined
• LED is lit blue: GPS position not determined / determinable
• LED off: GPS module is in sleeper mode / switched off / not present
14
RF status LED (4):
This LED shows whether the RF recipient of the wireless remote control has received a signal
from a valid remote control.
Observe that only correctly coupled remote controls are recognised and displayed. How to
couple a remote control can be taken from the corresponding chapter.
The LED has the following display information accordingly:
• LED flashes red: Signal received by valid remote control
• LED off: Waiting for signal
RF button:
You can reach the RF button with a pointed object through the corresponding opening. This
is required to couple a new / different wireless remote control with the product. For more on
this, see the corresponding chapter.
Reset button:
The device can be reset to factory settings with a pointed object. For more on this, see the
corresponding chapter.
Feedthrough GPS receiver:
The GPS receiver is delivered pre-assembled. The GPS receiver must be placed so that a sight
connection to the sky is present with as few obstacles as possible. Particularly observe panes
that are applied with film or vaporised because they interfere with or even block the GPS signal.
The same applies for front or rear window heatings.
External power supply:
Use pins 15 and 16 to supply the device with the vehicle’s battery voltage (permanent plus).
The voltage range is between 6 and 32 V/DC and thus matches nearly any important vehicle
voltage.
The current load may be up to 700 mA (peak) at bad GSM reception, active switching relays
and active GPS.
15
Two connections for speaker / microphone:
Either the included microphone or the speaker can be connected to the two RJ12 sockets. Both
sockets are assigned in precisely the same manner and switched in parallel.
The PIN assignment corresponds to that of a standard phone handset. Function
cannot be guaranteed for every phone handset.
External LED connection:
Pins 1 and 2 are intended for connection of the external LED. Please use recommended
accessories only (see www.conrad.com)
P+ switching plus recognition:
Connect a switching plus signal to pin 3 and 4. Functionally, however, this input only serves
to directly trigger an alarm because the switching plus refers to an impermissible action in the
„ALARM ENABLE“ mode.
The reference potential is GND from the external power supply (16). No voltage above 32 V
must be present here.
To avoid unintended short circuit for wiring, only the „P+“ pin (3) is assigned. The
other pin was not connected. Therefore, if no reaction appears when the switching
plus is activated, this pin may have been connected.
Switching inputs IN1 / IN2:
The pins 5 and 6 for „IN1“, as well as 7 and 8 for „IN2“ serve to recognise various switching
conditions in the vehicle. These lines can be directly connected, e.g. to lamps, door contacts
or other switchable consumers. An integrated rectifier and optocoupler protects the device
from polarity reversal and short circuit.
It must only be ensured that a voltage difference of at least 4 V and no more than 32 V is pending
between the two pins (no matter the polarity) and the respective switching input is recognised
as „HIGH“. A voltage of less than 2.5 V is securely interpreted as „LOW“. The area between
serves to prevent multiple alarming and can only be assigned to a level under specific
circumstances. For more on this, see the corresponding chapter.
16
Relay switching outputs OUT1 / OUT2:
The device has two relays with alternate contract that are intended for a voltage of 30 V and
a current of 2 A.
When a higher power is to be switched, the corresponding relays must be
connected externally.
The relays are not bistable and accordingly return to „OFF“ or „RESET“ when all voltage
supplies (battery, USB, external voltage) drop or a system reset is performed.
Observe that the device for the relays has no extra fuse installed. Therefore,
provide an external fuse if required (depending on application case).
Improper wiring and switching of impermissible consumers (buzzer, ignition plus)
may cause a risk of short circuit, fire and loss of the general operating permit.
Expansion port:
This port was intended for possible expansions. This is possibly available on our website
www.conrad.com as accessory for order number 841086).
USB connection:
You may use this USB connection to update the product firmware to the latest version. For this,
the corresponding update programmes may be provided on the product side at www.conrad.com.
The software version currently installed on the product can be taken from every answer text
message.
17
8.3 Notes on the Installation
• It can be installed in any position.
• Observe that there is enough space for cables when choosing the installation position.
Strongly bent cables (particularly right behind the plug) increase the risk of cable breaks and
may cause contact problems in the plug. The PCB is under a strong mechanical strain due
to this.
• To warrant the device function, choose a mounting site where the GMS network reception
is as good as possible.
• The application site should be protected against overheating of the device, excessive
moisture and dust.
• The product should be taken to a site where vehicle vibration can be measured.
• The product must not be subject to continuous strong vibrations (vibrating machines, direct
motor/chassis contact, etc.).
• The product is not protected against weather and therefore must be installed inside the
vehicle.
• Observe that the SIM card holder position was placed close to the casing holder on purpose.
You may use a corresponding screw to secure the SIM card against impermissible removal.
Replacing the battery:
If the battery must be replaced, observe the following instructions:
1. All removal cable connections must be removed from the device; separate it from the
power supply under all circumstances
2. Remove the SIM card.
3. Loosen the 4 screws on the product bottom; turn it out.
4. Now the casing may be used carefully; do not apply any force!
Observe the GPS receiver! It may be necessary to loosen the screws at the GPS
cables for relief.
5. The battery is connected to the main PCB via a plug secured against polarity reversal;
carefully disconnect the battery.
18
Any changes in the vehicle that become necessary for the installation of the alarm
system or other components must be carried out in such a way that neither traffic
security nor the constructional and functional stability of the car are affected.
The operation permit may lapse even when sawing out the sheet part.
No parts must be installed in the airbag trigger area because this may cause injury
to the vehicle passengers in case of accident.
Never loosen the plugs for an airbag, which may cause unintended triggering of the
airbag or functional impairment.
If there are any doubts regarding selection of the installation site, inquire for
information from your car vendor.
Before drilling the bores, make sure that no electric cables, brake lines, the fuel tank
or similar are damaged.
When using tools to install your alarm system, observe the tool manufacturer’s
safety information.
When installing the product, take into consideration the risk of accident which can
arise from devices being torn away in the case of an accident. Therefore, you should
secure every component in a place where it cannot be dangerous to passengers.
In doubt, installation must be performed by a specialist.
19
8.4 Notes on the Electrical Connection
• The maximum load resilience in the relays must not be exceeded. If required, they must be
protected from overload with additional external fuses.
• The external cables must be kept as short as possible and remaining line lengths must not
be coiled.
• Too-strong temperature fluctuations may lead to temporary impairment and require manual
reset in extreme cases.
• The product is not intended for the „Safety“ area and therefore does not correspond to any
SIL/ASIL level.
The electrical connection must be made by a specialist.
To avoid short circuits and resulting damage to the device, the negative pole (GND/
earth) must be disconnected during connection.
Only connect the negative pole of the vehicle battery when you have completely
connected the device and checked the connections.
Observe the notes of the vehicle manufacturer so that the stored data of the vehicle
are not lost (e.g. radio code).
You should only use a voltmeter or a diode test lamp for checking the voltage on
the on-board cables as normal test lamps consume excessive currents and can
thus damage the electronic system of the car.
When laying the cables, make sure that they are not squeezed or scoured on sharp
edges. Use rubber grommets for the feed-though points.
When placing the sensor lines in the trunk, use rubber sleeves or something similar
to avoid impairing tightness of the vehicle interior.
When placing the lines in door pillars, etc., ensure that you do not impair any safetyrelevant devices (e.g. side airbags). The lines must not be placed in the airbag
trigger area.

9. Commissioning - First Steps
Prior to commissioning the product, check whether it is suited for the intended application!
In case of doubt, always contact a specialist, expert or the manufacturer of the products used!
The following is needed for operation and configuration of the device:
• A common mobile phone with SIM card for configuration of the device.
• An additional SIM card (prepaid or contract) for the device.
• A voltage source (USB port or direct voltage source)
9.1 Operating Voltage
The product may be supplied with power via USB as well for testing. The battery LED shows
whether the operating voltage was connected correctly, no matter the device status:
• LED off = no external voltage supply
• LED green/red = external voltage supply present
9.2 Changing the PIN Code to „1513“
Every SIM card has a PIN code. Because the car alarm system uses its own PIN processing,
the SIM card PIN code must be changed to that of the product.
The following steps are required for this:
1. The SIM card intended for the car alarm system must be inserted in a mobile phone.
2. According to the operating instructions of the mobile phone, the PIN code must be
changed to 1513.
3. The SIM card with the changed PIN code must be removed from the mobile phone.
4. The SIM card with the changed PIN code can now be inserted in the intended device slot.
The SIM card slot for this is on the short device side.
