1. Before installation
The CA-1803BT GSM pager should only be installed by a professional
installer. It is designed to be installed inside a car. A voltage supply of 12V
or 24V is required with a negative ground connection. During the first
power-up, the value of supply voltage is read and the inputs are set to
The immobilizer relay contact of car alarm is connected only in disarmed
mode and if the ignition is on. Do not block circuits that are under voltage
while the ignition is off. It could cause a serious damage of the vehicle.
Disconnect the car battery before starting installation. For airbag-
equipped cars, no person is allowed to stay inside the car while handling
the battery. Disconnecting the battery can cause a reset of some of the
car’s devices (e.g. clock, default settings etc.). Avoid drilling into the metal
parts of the car body. The manufacturer is not responsible for damage
caused by any incorrect or unsuitable application of the product.
For crimping, special purpose tools should be used. If you do not use
some of the cables, cut them off at a distance of 10cm from the connector,
insulate them properly and tie them into a bunch.
For cars with a voltage supply of 24V, the following restrictions
apply to car alarm installation:
1. It is not possible to connect a hands-free set of type HF-03.
2. When used for acoustic signalling, the SIR output is switched to the
power supply voltage. Consequently, this output switches to 24V, so it
is necessary to use a siren of type SA-606-24V instead of the siren
which is supplied in the standard package.
2. The wiring
Yellow – output siren – switches to +12V (24 V) / max. 1.3 A for 30
seconds after input activation (optional).
Grey – instant activation. It reacts to connection or disconnection
from ground The reaction time is 70ms.
White – input INP. It reacts to a connection or a disconnection from
the ground The reaction time is 3 seconds.
Blue – signals that the ignition key is turned on. Reacts to +12V
(24V). When you are installing it inside a car, make sure that a voltage
is present in the connecting wire while starting. The activation of input
INP is blocked during the ignition key input activation and, if installed, a
hands free set can be used.
Green – LED indicator – should be installed in a visible place on the
Black – ground – connect to the original grounding point.
Red – power supply +12V (24V) - connect directly to the battery. The
power should be turned on only after a thorough check of the whole
installation has been made!
Orange – back-up battery – connects to a back-up battery of type BB-
02 (capacity 450 mAh, consumption up to 20 mA.). This feature is
2x Brown – immobilization circuit (max. 8A constantly, 12A
Pink – output AUX – bus communication for modules CR-11A
It is possible to attach a hands-free set of type HF-03
. Using this you are
able to phone via the GSM pager, and also to remotely listen-in after the
immobilization circuit has been blocked. The HF set connects to the RJ
connector on the front side of the car alarm unit.
3. SIM card insertion
1. Make sure, that the PIN number on the SIM is disabled. If the SIM
card does not allow you to switch the PIN off, set the PIN to 0000.
Remember (note down) the phone number of your SIM card. It is
recommended to delete all original records in the SIM card’s phone
2. Insertion of the SIM card: using a thin object, press the yellow peg
in order to pull out the SIM card holder (the front side of the unit),
these accessories are optional
insert the SIM card into the casing with the conducting contacts facing up
and push the casing back carefully up to the sticking point.
3. Install and attach the GSM antenna– (the GSM pager must not be
connected to a power supply unless a GSM antenna is connected !!!). The
antenna is equipped with an adhesive tape and has to be stuck onto the car’s
window. The antenna must not be installed to metal parts. The antenna should
not be installed close to the pager or near other electronic devices. It is
recommended to install the antenna in a place where it is not easily visible (like,
for instance, on a tinted part of the window). Clear and dry the spot carefully.
4. Install provided GPS antenna - place the antenna so that it will not be
shielded by metal parts of the car. It can be installed just under the top part of a
dashboard (turned with the black plastic cover upward) (the antenna can be
shielded by plastic materials). Wrap both connectors using plastic sticky tape as
they are connected to GND.
5. Check the wiring and connect the power supply. A flash of the indicator and
a beep of the siren (if connected) indicate connecting to the GSM network. Wait
until the indicator turns off (up to 1 minute). After that the CA-1803BT is logged
in to the GSM network.
If the flash does not disappear within 1 minute, it means that the login
process failed. If such a case occurs, turn off the power supply, pull out the
SIM card, ensure that the SIM contacts are clean, insert the card into a
mobile phone and check, whether a connection can be established in that
particular place. Also make sure that the SIM card‘s PIN is turned off (or that
it is set to 0000). If the mobile phone connection check is successful, return
the SIM card to the GSM pager and repeat the whole procedure. At least 10
unused positions for phone numbers are required in the SIM card memory.
4. After turning the power supply on
In order to use the functionality of the GSM pager according to your needs you
first have to set up its logic and behaviour by the RESET command.
Subsequently, phone numbers and other optional parameters should be set up
and an RC-8x key fob can be enrolled. The set-up can be done in the following
·by editing a record in the SIM card phone directory (it is the simplest
setting method but limited to some functions only, see table 5.1). These settings
(which determine the devices‘ behaviour) are read from the SIM card after each
powering up of the car alarm. After the initial powering up of the new car alarm
with a new (blank) SIM card, configuration records (names) are created in the
SIM card’s phone directory and the default values set. But in the case that the
alarm had been set before and a new (blank) SIM card is inserted then the
stored parameters are copied from the internal memory to the SIM card. This
will help you after SIM card changing. You can perform basic settings of some of
the car alarm’s functions by pulling the SIM card out of the alarm (after the
power supply has been disconnected) and subsequently inserting it into a
mobile phone where you assign numbers to the names of functions displayed in
the phone directory from the SIM. See table 5.1 for setting the car alarm’s
optional parameters. Settings from the SIM card are read after its insertion and
via the Internet page www.GSMLink.cz
which is the most convenient
way. To register there you need the registration code printed on the
warranty card and the master code (factory default is MASTER). For more
information, see chapter 10.
by sending command SMS messages via a mobile phone, see table 5.1.
Using the CA-1803BT as a GSM pager, it is necessary to set RESET EN 3.
You can perform it by an SMS instruction “MASTER RESET EN 3” which
has to be sent to the GSM pager’s SIM card number. Performing a RESET
is indicated by 4 beeps. The factory default is RESET 0 without any function
assigned, except that the immobilization relay switches on after the ignition
key has been turned on. It is possible to put the GSM pager to RESET 0
mode also in the case, that its functionality should be cancelled entirely.
By carrying out a RESET, you delete all the GSM pager settings as well as
all the previously enrolled remote controllers and wireless sensors.
