CHAPTER I: INTRODUCTION
Alcar®H51 is an auto alarm, remote controlled with hopping code. This facility offers a
stronger protection than the fixed code systems, since the remote control is changing the
code at each button pressing.
It is a user-friendly modular system that can be configured in a very complex way. The doors are
protected by pin-switches, apart from the trunk and the hood. The alarm assures the engine
killing. The command from the shock sensor (included in the basic kit) will pre-warn for weak
shocks. For strong shocks or repeated weak shocks the alarm will trigger in a specific way.
The ALCAR®H51 range has the following versions:
-ALCAR®H51 - ALCAR®H51  minimal kit,
-ALCAR®H51U- ALCAR®H51 + ultrasonic sensor incorporated;
-ALCAR®H51DL - ALCAR®H51 + central door lock module incorporated;
-ALCAR®H51P - ALCAR®H51 + auto-pager module incorporated;
- Any combination of the upper options (ex: ALCAR®H51UDLP- maximal configuration, with
ultrasonic sensor, with central door lock module and auto-pager module).
Supplementary external sensors can be connected, such as one-zone or two-zone microwave
sensor or ultrasonic sensor.
This way, the system assures the protection of the interior of the car and/or can warn when
someone gets close to the car.
NOTES:
1) In this manual ALCAR®H51 will be referred as the whole range of auto alarms of this
kind, meaning that such functions are optional for the various constructive versions;
2) In this manual the two buttons remote control is referred (button 1) and (button 2). If the
remote control has 4 buttons, then the first two only will be used for operating the car alarm. The
other two can be used for subsequent developments (ex: for garage doors command, for
operating a burglary alarm system etc).
CHAPTER II: THE KIT
In the box you will find the following:
1. Central unit 2. Remote controls (2 pcs.)
3. Pin-switch (2 pcs.) 4. Mounting cables (3 sets)
5. Warning decal (2 pcs) 6. Spare fuses (10A, 2A)
7. Shock sensor + cable 8. Engine killer relay
9. Ultrasonic microphones 10. Valet switch
11. State LED

sensors stabilization period) the shock sensor and/or the external supplementary sensor are
active. Check the fact that the system warns optical-acoustical by 3 short signals. Check also that
the power supply of the bypassed sensorswas disconnected on that specific arming period
(sensors LED is off and the alarm system does not respond when the sensor is tested).
6.1.1 Testing the detection of the burglary attempts
With the system armed simulate burglary attempts in all the possible ways:
1) Put the key in contact and try starting the engine; the relay contacts should open (the engine
should not start), and the system should trigger the alarm (by siren, flashing lights and optionally by
pager) for 30s (this is the alarm for engine starting attempt).
2) Open and close one by one all the doors, the hood and the trunk; the system should trigger the
alarm (by siren, flashing lights and optionally by pager) for 30s.
3) Open a door and leave it opened; the system should trigger the alarm (by siren, flashing lights
and optionally by pager) for 30s, three times subsequently. After that the doors input will be
bypassed the other functions of the system remaining active. If the door is closed eventually, the
input should become active again.
4) After passing the sensors stabilization period (20s after arming), hit the car slightly; the system
should prewarn (for weak shocks). After repeated shocks within 5s, the system should trigger the
alarm (by siren, flashing lights and optionally by pager) intermittently 2s ON, 1s OFF, for 15s
(repeated shocks alarm).
5) After the stabilization period passed (20s after arming command), hit in astrong manner the car;
the system should trigger the alarm (by siren, flashing lights and optionally by pager) intermittently
2s ON, 1s OFF, for 15s (strong shocks alarm).
6) If the system is provided with ultrasonic sensor and the input for the supplementary sensor is
programmed properly, then, aftyer the sensors stabilization period (20s after arming), by leaving the
window opened, introduce the arm inside, through the window; the system should trigger the alarm
(by siren, flashing lights and optionally by pager) for 30s (alarm for violating the interior of the car).
7) If the system is provided with proximity sensor (microwave sensor), and the input for the
supplementary sensor is programmed properly, then, after sensors stabilization period (20s after
arming), when approaching the car, within sensors range, the system should emit one signal at
every detection, according to the value of the parameter 11 (warning for approaching the car).
6.1.2 Testing the central door lock commands
If the car is provided with central door lock check if:
a) Doors are locked when arming the system.
b) Doors are unlocked when disarming the system (if parameter 6 is active).
c) Doors are unlocked when turning off the engine (if parameter 7 is active).
d) Doors are locked when turning on the engine (if parameter 8 is active).
e) Doors are not locked when the system is passive arming, after 30s after turning off the engine
and closing the last door (if parameter 4 passive arming is active).

Notes:
a) If the system is armed with silent alarm function (no siren), the alarm state will be notified by
pager and flashing lights or only by pager, according to the value of parameter 9 (see 5.2., system
parameters);
b) Any alarm state can be stopped by pressing shortly (0.5s) the button 1 or 2, without disarming
the system. For disarming the system when the alarm is in progress, press button 1 twice (once to
stop the alarm and second time to disarm the system).
5.18 COMFORT FUNCTION
The Comfort function is available for some newer models of cars. At these cars, when twisting the
key the doors will lock. If maintaining the key twisted for more than 5s then the windows will roll up.
The Comfort function provides when arming a longer trigger (10s) on the lock doors output, no
matter of parameter 1 value.
Caution!
Do not run this wire directly to the door lock actuator, but to the command wires existing on the car!
For details please call the manufacturer!
5.19 DOOR CONTACTS DELAY, WHEN ARMING
This function is only used for the cars which maintain ON the dome lamp, a certain time, after the
last door is closed. In this case, the parameter 11  Door contacts delay, when arming will be
programmed actively. Then, the state of the door pin switches is only tested after the delay time
estabilished by parameter 12.
If after delay time, the alarm system detects at least a door opened, it notifies by 3 opto-acoustic
signals and bypasses the respective input. If afterwards all the doors will be closed, the respective
input becomes actively again. The signal for the door inputs will be taken from the (+) terminal of the
dome lamp.
CHAPTER VI: TESTING/ADJUSTMENTS
6.1 REAL CONDITIONS TESTING
1) Stop the engine, close the doors, the hood and the trunk. Arm and disarm the system with and
without acoustical confirmation like. The state LEDwill indicate as follows:
- blinking slow  system is armed;
- off  system is disarmed;
- on  system is in alarm;
- blinking fast  system is within the 30s after disarm command, when it is waiting for a
door to be opened (see 5.9).
- system is within 30s after the engine was turned off and the last door was closed and it is
counting the time for passive arming (see 5.10).
- short blinks  after disarming and closing the last door the system indicates the alarm memory or
the faulty inputs type; while in programming mode the system indicates the parameters values.
2) Arm the system and bypass manually by remote control the sensors according to 5.5.5. Check
the fact that power supply of the bypassed sensor was disabled while armed (sensors LED is off
and the alarm system does not respond when the sensor is tested).
3) Arm the system and simulate various situations so, after 20s from arming (at the end of the

CHAPTER IV INSTALLATION
During this section there are presented the location, the mounting and the electrical connections
necessary for the alarm system installation.
This alarm system can only be installed on cars that have the negative pole of the
battery connected to the chassis!
NOTE: Read carefully this manual before starting the installation. If you are not sure you are able
to do it by yourself, call a specialist!
4.1 SIREN MOUNTING
The siren will be mounted in the hood compartment, away from high temperature sources and
humidity. The chosen place should not be obstructed in order not to attenuate the siren sound.
Also, the place should be as inaccessible as possible to prevent the tamper.
Fasten the siren up side down by using screws.
4.2 PIN SWITCH MOUNTING AT HOOD AND TRUNK
Choose the mounting place such as the pin-switches should be able to move about 6mm. in the
closed position of the hood and trunk.
4.3 CENTRAL UNIT MOUNTING
Choose a horizontal place, hidden, preferably under dashboard. Fasten the central unit with screws
on the car chassis.
4.4 CONNECTIONS
There are 8 connectors on the central unit (A, B, C, D, E, F, G, H). The connectors correspond
respectively to the cable sets A, B, C, D, F, G, H.
The connections will be made according to the general mounting diagram (D).
4.4.1 Cable set A
Commands the central door lock system.
The timing for commanding the central door lock system can be set to 0,8s. for electric door
lock and 4s. respectively for pneumatic door lock. The selection is made through parameter
1-Timing for door lock.
Before connecting the cable A and setting parameter 1, one should determine the type of central
door lock existent on the car. A simple way is to try and lock the car doors by locking the right-front
door, by locking this door:
1) the doors are instantly closing, then the car is provided with electric door lock system
2) the doors are closing in an interval of few seconds, then the car is provided with pneumatic
door lock system
4.4.2 Cable set B
B1 (black)
System GND. Connect to (-) pole of the battery.
Note: In order to improve the noise immunity it is indicated that the power supply wires (B2-red and
B1-black) to be connected directly to the batterys poles.
20
5.14 BYPASSED FAULTED INPUTS INDICATION
If when arming the system has bypassed any input (doors, hood, sensors) within 20s after arming,
then whn disarming, after opening any door the hood or trunk, the system will indicate by the state
LED, the type of input as follows:
1 blink - shock sensor
2 blinks - ultrasonic sensor
3 blinks - contact key (attempt to start the engine)
4 blinks - door contacts
5 blinks- hood, trunk contacts
After starting the engine the faulted inputs memory will be reset and the LED will turn off.
The alarm memory is prioritary towards the faulty sensors indication. So, the LED will indicate the
faulty inputs bypassed only if there was no alarm.
5.15 ANTISCANNING/ANTIGRABBING
ALCAR®-51, is protected for scanning and grabbing.
5.16 NON-VOLATILE MEMORY FOR SYSTEM STATES
When the system is powered again (after the power was OFF), it enters the state which was
previously (armed, disarmed, service, anti-carjacking). If the system was in the arming mode when
the power was OFF, then at the power restoring the sensors state and the event memory will be
restored and the system will tripp a panic alarm.
Note: There is a certain situation namely: if parameter 11  Door contacts delay when arming is
enabled, parameter 12  Door contacts delay duration is 5s, a door is opened when arming and
the power is breaked before the fifth second from the arming, then when rearming, if the door is still
open, the system enters a door alarm .
5.17 ALARM SITUATIONS WHEN THE SYSTEM IS ARMED
1. When opening a door, the hood or the trunk  alarm by siren, flashing lights and optionally
by pager, for 30s;
If a door is left opened in a burglary attempt, the system triggers the alarm (siren, flashing lights and
pager), for three times of 30s each. After the 3 x 30s alarm sequence the doors input is bypassed
and the other functions of the system are still active. This is executed even if the alarm is stopped
by remote control.
If subsequently the related door is closed, the doors input becomes active again.
2. When trying to start the engine with the key  alarm by siren, flashing lights and optionally
by pager, for 30s;
3. When the car receives a weak shock optical-acoustical warning for 1s.
4. When the car receives repeated weak shocks within 5s or a strong shock  alarm by
siren, flashing lights and optionally by pager, for 15s, intermittently 2s ON, 1s OFF;
5. When violating the interior of the car, if the supplementary input is set for ultrasonic
sensor alarm by siren, flashing lights and optionally by pager, for 30s;
6. When approaching the car, if the supplementary input is set for proximity sensor 
programmable warning (see parameter 10).

B2 (red)
General power supply of the system. Check the 2A fuse and connect to (+) pole of the battery
together with the pink wire (B5).
B3 (purple)
Open collector PNP output, maximum 1A (positive trigger).
The output state is related to the Parameter 0 value in the following way:
Parameter 0 = 1 Parameter 0 = 2
In normal state GND +12V
When active +12V GND
Generally there are 3 types of siren, which are:
1) Normal siren, which provides two wires (+) and (GND).
Parameter 0 should be set as 1 and the siren should be connected as follows:
- (+) to B3;
- (GND) to GND;
2) Back-up siren, with three wires: (+), (GND) and (COMMAND). On the (COMMAND) wire
there should be permanently (+), while the siren is powered ON. Thus, when removing (+) from the
(COMMAND) wire, the siren should sound.
Parameter 0 should be set as 2 and the siren should be connected as follows:
- (+) to (+12V);
- (GND) to GND;
- (COMMAND) to B3.
3) Back-up siren, with four wires: (+), (GND), (NEG.TRIG) and (POSITIVE TRIG). While the siren
is powered ON, it will sound either when (NEG.TRIG) is connected to GND or when (POSITIVE TRIG)
is connected to (+12V). On the (COMMAND) wire there should be permanently (+),Thus, when
removing (+) from the (COMMAND) wire, the siren will sound.
Parameter 0 might be set either 1 or 2 and the siren should be connected as follows:
- (+)to (+12V);
- (GND) to GND;
- (POSITIVE TRIG) to B3 if Param. 0 is 1;
- (NEG.TRIG) to B3 if Param. 0 is 2;
B4, B6 (gray)
Connect to (+) pole of the signaling lamps left and right respectively.
B5 (pink)
Power supply for the signaling lamps. Check the 10A fuse and connect to (+) pole of the car battery
together with the red wire (B2).
4.4.3 Cable set C
C1 (orange)  open collector, negative trigger, and maximum 500mA load output for window
closing when arming the system. The output is active all the time while the system armed. It
commands an optional module type RB-06.

5.9 AUTOARMING
To assure the protection against accidental disarming of the system, if after disarming command,
within 30s there is no door opened or the engine is not turned on, the alarm system will arm
automatically.
This function is permanently active.
5.10 PASSIVE ARMING/WARNING AT PASSIVE ARMING/TEMPORARY DISABLE OF PASSIVE ARMING
If parameter 4 (passive arming- disabled by default) is set enabled, the system will arm passive
after 30s from turning off the engine and the last door closed.
After closing the last door, the system will notify by an optical-acoustical signal (default) or just
optical, for silent disarming.
If the parameter 5 is enabled, the passive arming can temporary disable by opening and closing
twice a door within 5s.
The passive arming is useful since it prevents forgetting the car disarmed. The passive arming is
made without locking doors.
5.11 REMOTE CONTROLLED DOORS LOCK/UNLOCK AND/OR WHEN SWITCHING ON/OFF THE
ENGINE
If the car is provided with central door lock the system will lock the doors when arming and unlock
the doors when disarming (according to the value of parameter 6).
Also, the system can unlock the doors when turning the engine off (see parameter 7) or lock the
doors when turning the engine on (see parameter 8).
5.12 DUAL MODE
This referrs to the possibility of triggering the alarm by the ultrasonic sensor only if within 15s are
activated at least two sensor types (ultrasonic + proximity or ultrasonic + shock).
That means that if parameter 14 (Dual mode) is enabled the alarm triggering by the ultrasonic sensor
can only be done if the interior detection was preceded or succeeded within 15s by another sensor
triggering (shock or proximity).
It is strongly recommended to use dual mode only when the system is provided with all sensors
type (shock, ultrasonic and proximity). This mode is useful under these circumstances because it
prevents false alarms. Enabling/disabling this mode is made by enabling/disabling parameter 14.
It is not recommended to use the dual mode if the system is not provided with proximity sensor.
5.13 ALARM MEMORY INDICATION
If while armed at least an alarm was recorded, after disarming and opening the door, the system will
indicate by the state LED the type of the sensor that triggered the alarm, as follows:
1 blink - shock sensor
2 blinks - ultrasonic sensor
3 blinks - contact key (attempt to start the engine)
4 blinks - door contacts
5 blinks- hood, trunk contacts
After starting the engine the alarm memory will be reset and the LED will turn off.

C2 (brown)  input for checking the engine state ON/OFF. Connect to ON wire (coil) of the
contact key switch.
In order to find this wire:
- Switch the key in contact until the lights in the dashboard turn on;
- Search on the contact key hub the wire on which the voltage is +12V; In this position and in
START position too, the voltage on this wire should remain +12V.
NOTE!
There is another wire, marked sometimes ACCESSORIES, used to power up some accessories
(radio, cooler etc.), which provides +12V with the key in hub and the engine turned on. However, in
START position the +12V voltage is not provided anymore. Do not confuse with this one!
C3 (green + white)  negative triggered input, for trunk and hood state closed/opened.
C4 (green)  negative triggered input, for doors state closed/opened.
Note:
For C3 and C4 negative triggered inputs is important the doors switches type!
One can check by using a voltmeter the switching type of the doors switches, this way:
1. Open a door and locate the door switch.
2. Connect the voltmeter between GND and the main contact of the switch.
3. If the inside lamp turns on and the voltmeter indicates 0V then the switching is negative. In
this case the doors switches will be connected directly to C4, in parallel, according to general
mounting diagram (D)
4. If the voltmeter indicates 12V, then the switching is positive. In this case the connection will
be made by means of a relay according to diagram C.

C7 (yellow) - open collector, negative trigger and maximum 500mA load output for command of the
external engine killer relay.
In order to use anti-carjacking function, the engine killing will be made on the injection pump, fuel
pump, coil etc.

b) From this point the system waits 30s, then it returns to the upper state 3, resuming the warning
signals. If the button 2 of the remote control is pressed again, with contact key in OFF position only,
the system leaves the anti-carjacking mode. It emits 1 acoustic signal for 1s, followed by 2 optical
signals and it enters the disarming mode.
c) If the button 2 is not pressed and the system reaches the state 4, then the exit procedure should
be executed again from point a).
Note:
After entering the anti-carjacking procedure, if the alarm power supply is disconnected, when the
system is powered up again it will enter anti-carjacking state.
5.5.9 Trunk release function
If an interface module RB-04 is connected, for trunk release, it will be actionated pressing long, for
about 2s, button 2 of the remote control.
The function is active only when the system is disarmed and the engine turned off.
5.5.10 Two level - Door unlocking, when disarming
For two level  door unlocking when disarming the system should be provided with the diode D19
on board. This way, the parameter 6 (unlocking doors when disarming) should be inactivated.
In this configuration the system doesnt unlock the doors when disarming while pressing the button
1. For unlocking the doors by remote the button 2 must be pressed more than 2 seconds. Once this
option enabled the trunk release function is not anymore available!
5.5.11 Two steps disarming
Any alarm state can be stoped pressing the button 1 or 2 for short time (aprox. 2s) without the
system to be disarmed. For system disarming when the alarm is triggered, the button 1 should be
pressed twice (once for alarm stoping and seconnd for disarming).
5.6 ELECTRIC WINDOWS CLOSING WHEN ARMING
When arming the system, if there is connected an optional module RB-06, then the windows will
close automatically.
5.7 REVERSE CAR MOVING WARNING
When moving backwards the system warns by optical-acoustical signals (or just optical if the
system was disarmed silent), according to the setting of parameter 2 (see system parameters
programming). This parameter is enabled by default for optical-acoustic notification.
Also, when disarming silent, the reverse car warning is optical only.
5.8 DOOR OPENED WARNING
If, after the engine is turned on, one of the doors remains opened for more than 15s, the system will
warn by 6 optical-acoustical signals, or just optical, according to the value of parameter 3 (see
system parameters programming). This parameter is set by default for optical-acoustical warn-
ing.
If the disarming was silent, the door-opened warning is optically only.
If a door is opened while riding, the system wil emit the same warning signals, after 15s.
Also, the same warning signals will be emitted when the hood or the trunk are opened.

4.4.4 Dconnector
It is the connector for the state LED. It is recommended to mount the LED in a visible place (usually
on the dashboard), in order to notify the existence of the alarm system and to discourage an
eventual burglary attempt.
4.4.5 Econnector
The shock sensor ES-21K will be mounted on this connector. It is recommended to locate the shock
in the center of the car to detect the shocks from any part of the car. The sensor sensitivity is
adjustable. The power up of the sensor is cut off when the sensor is bypassed (by remote control
or when it if found faulted when arming).
4.4.6 Fconnector
An external optional sensor can be connected on this connector (microwave or ultrasonic sensor).
This connector is provided with 4 (optionally 5) connection pins:

NOTE!
If the both buttons of the remote are pressed simultaneously during the first 5s after arming, the
silent alarm function will be enabled (during respective arming period the siren will be disabled).
The silent alarm function enabling will be confirmed by 2 optical-acoustic signals (or optical signals,
depending on arming mode).
5.5.7 Signalling the remote controls number
The hopping code remote controls of ALCAR®-H51, are learnt by the central unit through the
procedure described in chapter 5.1  Learning/clearing remote controls. The remote controls
number, recorded in central units memory (up to 4), can be notified by a simple short press of
button 2 while in disarmed mode. The system answers by a number of optical-acoustical
signals (or optical only if the system was disarmed silent) equal to the remote controls number.
Note!
1) While disarmed, when the engine is turned off, pressing long (more than 2s.) the button 2
will activate the trunk release output;
2) While disarmed, when the engine is turned on, if parameter 13 (anti-car jacking) is enabled,
by pressing long (more than 2s.) the button 2 will enter the anti-car jacking mode.
5.5.8 Anti-carjacking mode
The function is necessary in the case when the burglar threats the owner and takes the car in its
presence, with the key in contact. Once the function is triggered, the car will stop after 1min. and
will enter the anti-carjacking alarm mode..
The function should be enabled when setting the system parameters (see 5.2, parameter 13), and
the external 40A/12V relay should be connected to cut the induction coil the injection pump etc. The
function doesnt work if the external relay cuts the engine starter!
Note!
The car owner should have another remote control apart from the keys!
To trigger anti-carjacking procedure presslong (about 2s) button 2, when the engine is
turned on. The system will enter the procedure and will confirm by flashing lights for 2s. After the
confirmation the alarm passes the following states:
1) During first 14s the alarm does not respond to any remote control command;
2) In the following 16s one can leave the anti-carjacking following the exit procedure;
3) In the following 30s the alarm emitts short siren sounds and optical signals, warning that the
engine will turn off. One can leave the anti-carjacking following the exit procedure.
4) After expiry of the 60s, the alarm enters the anti-carjacking alarm mode, in which the engine
stops, the sirens sounds continuously and the flashing lights are on until the battery is completely
discharged. One can leave the anti-carjacking following the exit procedure.
To exit anti-carjacking mode you must follow the procedure bellow:
a) In any state 2, 3 or 4 previously enumerated press the button 2 of remote control. The warning or
the alarm sounds will be stoped. The engine killing will be stoped (if the system was in state 4) and
the system will emit 1 optical signal for 2s, followed by 2 optical-acoustic signals.

1) GND;
2) Warning input (when detecting movement around the car);
3) Alarm input (when detecting movement inside the car);
4) Commanded power up for the optional microwave sensor;
5) Commanded power up for the optional ultrasonic sensor;
The connector has 4 pins for standard configuration. Optional, when an internal sensor is mounted
besides the built-in sensor, the central unit has to be properly equippated (to assure a separate
power supply for ultrasonic sensor / sensors and microwave sensor).
These external sensors should provide a negative trigger output when activated.
The central unit commands separately the sensors power supplies. They are interrupted when
bypassing the sensors (by remote control or when it if found faulted when arming).
The external sensors sensitivity is adjustable.
NOTE: For all sensors, adjusting the trimmer to the left or to the right the sensitivity decreases or
increases respectively.
4.4.7 G Connector
This is the connector for the push-button (valet switch). This switch it is used for:
- Remote controls learning;
- Service mode / emergency disarming;
- System parameters programming.
NOTE!
The push-button should be mounted in a hidden place known by the owner only!
4.4.8 H connector
This one connects the ultrasonic sensor microphones.
4.4.9 Pager connecting
Pager connecting is optional. The related module, by default is not included in the basic kit.
CHAPTER V: SYSTEM OPERATING
5.1 LEARNING / CLEARING REMOTE CONTROLS
The central unit already knows the two remote controls provided with the basic kit. Up to four
remote controls can be learnt by the central unit.
In order to learn or clear from memory remote controls, one should do the following:
1) Disarm the system;
2) Switch the engine contact key twice, such as the key switches subsequently
between: ON, OFF, ON, OFF;
3) Press the push-button three times within 15s. A success-
ful enter in learn/clear mode will be confirmed by two optical and acoustical signals;
4) For learning, press one of the remote controls buttons within 15s. after pressing the push-

by an optical-acoustic or optical signal (depending on arming mode) and advances to the next
sensor.
If the button 2 of the remote control is pressed, the system doest bypass the sensor, but it
advances to the next sensor and confirms by optical-acoustic or optical signal.
Sensors bypass is only available for that respective arming period. When disarming the system the
bypass is disabled.
Example: If one wishes to bypass the shock sensor only it will proceed as follows:
1. During the first 5s after the arming command press button 2 to advance at the shock sensor
without bypassing the proximity sensor. The system confirms by an optical-acoustical signal (or
just optical if the arming was silent).
2. Press button 1 to bypass the shock sensor. The system confirms by an optical-acoustical
signal (or just optical if the arming was silent).
3. Press button 2 for not bypassing the ultrasonic sensor. If the button 2 is pressed the system
confirms by an optical-acoustical signal (or just optical if the arming was silent).
5.5.4 Arming with silent alarm
If the owner dos not want the theft to be warned, then the system can be armed with silent alarm
(the siren is disabled). The using of this function is needed when the system has a pager. The alarm
state will be notified on page and flashing lights only, according to the value of parameter 9 (see 5.2.
system parameters).
The silent alarm function can only be activated within the first 5s after the arming command,
by simultaneously pressing both remote control buttons. The function is active during that
specific arming period only. The function enabling is confirmed by 2 optical-acoustic signals (or only
optical signals for silent arming). When disarming the system, the function is disabled.
5.5.5 Car finding
In order to locate the car in a full parking area, press shortly (0.5s) the button 2. Five optical and
acoustical signals will be provided. The signals will be:
- short if no alarm was reported meanwhile;
- long if there was an alarm since the system was armed
This function is active with the system armed only.
NOTE!
The car finding function is not active during the reserved 5s after the arming command.
If the button 2 is pressed during the first 5s after arming this command will be interpreteted
according to sensors disabling by remote control procedure.
5.5.6 Panic
In case of emergency, pressing shortly (0.5s) and simultaneously the two buttons of a
remote control can trigger the alarm. The siren will sound continuously, the pager will emit the
alarm signal (if there is provided a pager, which is optional) and the flashing lights will flash for
three minutes.
This function is used to discourage a potential burglar, and to draw the attention towards the
vehicle.
The function is enabled no matter of the systems state (armed/disarmed), except the first 5s after
arming and can be stopped during the thre minutes by pressing shortly any of the buttons.

button; a successful learning will be confirmed by an optical-acoustical signal;
5) To clear all the remote controls from the central unit memory press simultaneously both
remote control buttons of a known remote control. The clearing of all remote controls at
once will be confirmed by three optical-acoustical signals;
6) To leave the learn mode switch the contact key to ON position. Also, leaving the learn
mode will automatically be made after 15s. in which there is no remote control button pressed.
Notes:
a) The remote controls record in the central unit memory is made cyclically from location 1 to location
4, respecting FIFO principle (First In First Out). So, if the memory is full, the oldest remote control will
be erased when learning a new one.
b) By simultaneously pressing bot buttons of a new remote control, while in learning mode, then the
system will learn that remote control. (It will not be executed the operation of clearing all the remote
controls).
c) If the same remote control is learnt twice, it will be confirmed second time too, but it will not fill a
second memory location.
1) In the case a remote control was stolen or lost a clearing of all the remote
controls at once operation will be effected. Then, the remained remote controls and the new ones
will be learnt
2) In the case all remote control were stolen or lost a new remote control learning
operation will be effected. Then a clearing of all the remote controls at once operation will be
effected followed by a learning operation for the new remote controls.

the remote controls is about 30m. The remote control is provided to 2 buttons, which will be referred
as 1 and 2.
The remote control is also provided with a LED that turns on when pressing any of the buttons. If
one note decreasing of the light intensity of the LED then the battery should be replaced.
Combining the two buttons it results a lot of functions that will be explained in the followings.
5.5.1 Arming/disarming with confirmation by siren chirps and flashing lights
System arming/disarming is simply made by shortly pressing (about 0,5s.) button 1. The
system toggles to one state or another according to the current state.
The arming confirmation is made both optically and acoustically, by one signal, and the
disarming confirmation will be made by two optical-acoustical signals (on flashing lights and
siren).
When arming:
1) If the system detects the hood, the trunk or a door opened, it warns by three optical-acoustical
signals and bypasses the respective inputs during arming. If afterwards the respective inputs are
restored (closing the hood, trunk or doors) they become active.
After sensors stabilization delay (20s. after arming), by opening again any door, the hood or the
trunk the alarm will be triggered.
2) If the system detects the position lights turned on, it will warn by a signal similar to the proximity
approach warning, according to the value of parameter 10.
When disarming, if the alarm has been triggered while armed, four optical-acoustical signals will
be emitted.
Note:
1) After arming the first 5s. are reserved for supplemental commands such as:
2) manual sensors bypass by remote control (the proximity sensor, the shock sensor and the
ultrasonic sensor);
3) silent alarm enabling (the siren is disabled);
4) System disarming can only be made after the 5s after arming command;
5) If the parameter 11 - Door contacts delay when arming is enabled, then the doors pin-
switches are tested only after delay duration estabilished by parameter 12. If, the delay duration is
over and the system detects at least one opened door, it will warn by three optical-acoustical
signals and it will bypass the respective input during arming.
6) If afterwards all the doors are closed, the respective input becomes active again, after
sensors stabilization delay (20s after arming).
5.5.2 Arming/disarming silent
When no acoustical confirmation is needed, press the button 1 for about 2s instead of the short
press described before (0.5s). All the signals will become silent, meaning that the optical confirma-
tion only will remain active for respective arming/disarming period (warning for reverse car moving,
for door open, for arming with position lights turned ON, for silent siren, for sensors bypassing by
remote control, for doors, hood and trunck bypassing, for faulted sensors disabling when arming).
5.5.3 Remote controlled bypassing the sensors
Remote controlled bypassing the sensors can only be made during the first 5s after the
arming command. The bypass order is: proximity sensor -> shock sensor -> ultrasonic
sensor.
If the button 1 of the remote control is pressed, the system bypasses respective sensor, confirms
