Installation Recommendations

To ensure reliable operation, the manufacturer recommends:

• Qualified Installer: Choose a qualified vehicle alarm system installer to install the immobilizer.
• Environment: Device location shall be free from moisture and other corrosive substances, as far as possible from heating elements and sources of electromagnetic interference (e.g., a vehicle computer, fans, relay blocks).
• Mounting: Do not install the System Unit directly onto metal parts of the vehicle to prevent the condensation accumulation inside.
• Orientation: Install the System Unit in such a way that the wiring connectors come from below.
• Wiring: Do not locate the System wires next to moving or heavily heated parts of the vehicle.
• Safety: Power supply and additional circuits must be fused.

Entering Service Mode

PIN code entering logic

The Service Mode can be activated if the ID card is lost, battery is discharged, or during car repair. It is activated by entering a PIN code.

PIN Entering Steps (Example 2113)

1. By Ignition: Turn ignition ON/OFF and count System LED flashes. Wait for double flashes to confirm each digit.
2. By Button: Press and hold the button for 1 second for each unit of the digit.
3. Mode Confirmation: After the last digit, wait for:
   • Triple flashes: ID card Pairing Mode.
   • Quadruple flashes: Full Service Mode.

Pairing ID Cards and IMB6 Relay

Pairing Process

1. Enter Pairing Mode: Enter the PIN code and wait for triple flashes.
2. Activation: Within 2 seconds, turn the ignition ON and OFF. Control time is extended to 12 seconds.
3. Pairing: Press and hold the button on the ID card (must be in passive orange mode) or IMB6. A 1-second flash confirms success.

FN	FUNCTION	SN	SETTING DESCRIPTION	EU	IMB5
FN=11	END OF FN SETTINGS	—	Function: END OF FN SETTINGS	✔	ⓥ
FN=21	IMMOBILIZATION SIGNAL	SN=1	The immobilization signal is turned ON when the 20-second time after the ignition is turned OFF is elapsed, if there is no paired ID card signal inside communication area. The signal is turned OFF when paired ID card signal appears and authorization button is pressed (depending on FN64 setting).	✔	ⓥ
		SN=2	Immobilization signal is turned OFF.	✔	✔
FN=22	ANTI-CARJACK	SN=1	'Anti-carjack' is turned OFF.	✔	ⓥ
		SN=2	'Anti-carjack' procedure is triggered by ignition turning ON with no active paired ID card inside communication area or by ID card signal loss with ignition is turned ON. The immobilizer waits for paired ID card signal within 120-second countdown and follows 'anti-carjack' operation settings (FN23). From the 25th last second to 11th last second the immobilizer warns by short buzzer signals with increasing frequency. Within the last 10 seconds buzzer sounds continuously. 'Anti-carjack' operation cancelling or trigger prevention available at any time by paired active ID card signal. If is selected (SN=2 for FN64) and immobilization signal is turned OFF (SN=2 for FN21), the authorization button shall be pressed every time when the ignition is turned ON.	—	✔
		SN=3	'Anti-carjack' procedure is triggered by ignition turning ON with no active paired ID card inside communication area. The immobilizer waits for paired ID card signal within 60-second countdown and follows 'anti-carjack' operation settings (FN23). From the 25th last second to 11th last second the immobilizer warns by short buzzer signals with increasing frequency. Within the last 10 seconds buzzer sounds continuously. 'Anti-carjack' operation cancelling or trigger prevention available at any time by paired ID card signal. If is selected (SN=2 for FN64) and immobilization signal is turned OFF (SN=2 for FN21), the authorization button shall be pressed every time when the ignition is turned ON.	—	✔
		SN=4	'Anti-carjack' procedure is triggered by ignition turning ON with no active paired ID card inside communication area or by opening the door with ignition turned ON and the ID card signal loss afterwards. The immobilizer waits for paired ID card signal within 60-second countdown and follows 'anti-carjack' operation settings (FN23). From the 25th last second to 11th last second the immobilizer warns by short buzzer signals with increasing frequency. Within the last 10 seconds buzzer sounds continuously. 'Anti-carjack' operation cancelling or trigger prevention available at any time by paired ID card signal. If is selected (SN=2 for FN64) and immobilization signal is turned OFF (SN=2 for FN21), the authorization button shall be pressed every time when the ignition is turned ON.	—	✔
FN=23	IMMOBILIZATION SIGNAL DURING 'ANTI-CARJACK' OPERATION	SN=1	With the last 15 override time seconds the buzzer signal becomes continuous, after 15 seconds the buzzer signal is turned OFF and immobilization signal is turned ON. The immobilization signal can be transfered to OC1 (SN=1, SN=4 for FN51), to alarm system (SN=5 for FN51) or to external immobilization equipment (SN=2, SN=6 for FN51). For immobilization signal cancelling is necessary the turned ON programmed ID card inside communication area and the authorization button press (depending on FN61, FN64 settings).	—	ⓥ
		SN=2	With the last 15 override time seconds the buzzer signal becomes continuous, you can turn OFF it only by turning OFF the ignition, but not earlier as the override time elapses. The immobilization signal is turned ON only as the ignition is turned OFF, it can be transfered to OC1 (SN=1, SN=4 for FN51), to alarm system (SN=5 for FN51) or external immobilization equipment (SN=2, SN=6 for FN51). For immobilization signal cancelling is necessary the turned ON programmed ID card inside communication area and the authorization button press (depending on FN61, FN64 settings).	—	✔
