GN7C Installation Manual

1. SECURITY INFORMATION

Pic. 1. Alarm System GN7C. The System Unit. Identification sticker, date and PIN code.

The vehicle alarm system shall be installed inside the passenger compartment of the vehicle, in a place difficult to access in accordance with the manufacturer's supplied wiring instructions.

The manufacturer of the alarm system recommends the following:

• Qualified Installation: Choose a qualified vehicle alarm system installer to fit the device.
• Environment: The system unit (see Pic 1) shall be installed in a place free from moisture and other elements that could pose to corrode the device.
• Interference: Install as far as possible from any heat-emitting elements in the passenger compartment and sources of electromagnetic interference (e.g., vehicle computer, fans, relay blocks).
• Condensate Prevention: Avoid mounting the System unit directly onto metal parts of the vehicle to prevent the accumulation of condensate.
• Orientation: Install the System Unit so that the wire connectors exit from the bottom side of the unit.
• Safety: Avoid placing wires next to moving or hot parts of the vehicle.

4. VEHICLE SELECTION AND ALARM SYSTEM CONFIGURATION BY COMPUTER

Launch the GN7C Loader configuration software and connect the Alarm System to a PC via the Micro-USB interface.

Pic. 3. GN7C Loader software interface for vehicle selection and settings.

Follow these steps to configure the system:

1. Select a car from the list: Choose the correct manufacturer, model, and production year.
2. Select modification: Some cars may have several modifications of the CAN bus. Select "mod 1" and test if the System is working. If not, switch to the next modification.
3. Enable CAN control: Turn ON the control via CAN bus. For some cars, you can select from several control programs; select the first from the list and check if the control is working. If not, select the next program.
4. Setup settings: Configure the required Alarm System settings (e.g., siren behavior, sensor sensitivity).
5. Save data: Save the selected vehicle data and settings to the unit.

4.1. Signals Monitored via CAN Bus

The system allows monitoring various vehicle zones through the CAN bus, such as:

• Ignition status
• Doors (Driver, Passenger, Rear)
• Hood and Trunk status

5. DIRECTION INDICATORS

Select one of the ways to connect the direction indicators:

Pic. 4. Wiring diagrams for different direction indicator connection options (A through E).

• A - The control of the direction indicators via CAN bus is possible in the car. No additional connections are necessary.
• B - The connecting to the Hazard Warning Button and the monitoring of the direction indicator flashes via CAN bus are possible in the car.
• C - The connecting to the Hazard Warning Button is possible in the car, however the monitoring of the direction indicator flashes via CAN bus is not possible. The analog input configured for monitoring of the direction indicator flashes is used.
• D - The connecting to the Hazard Warning button is possible in the car, however the direction indicator flashes are not under monitoring (not recommended way to control the direction indicator).
• E - The control of the direction indicators via CAN bus and the connecting to the Hazard Warning Button are impossible in the car. The direction indicators are controlled by switching the 12V voltage directly via built-in relay.

6. ADDITIONAL EQUIPMENT WIRING DIAGRAM

Follow these guidelines when connecting additional peripheral equipment to the alarm system:

Pic. 5. Additional equipment wiring diagram.

1. Buzzer: Connect and install the buzzer (applicable for alarm system versions with ID card reader - GN7C.HUPS).
2. Hood Switch: If the alarm system does not monitor the hood switch status via CAN bus, or if the car lacks an original equipment (OM) hood switch, install and connect an external hood switch.
3. Electronic Siren: If an electronic siren is used instead of a loudspeaker-type siren, install it as shown in the wiring diagram and change the setting to SN=5 for FN65.
4. Optional Controls: If additional equipment is installed (e.g., additional engine immobilization circuits, engine preheating modules), connect them using the Optional control No.1 and Optional control No.2 outputs. The purpose of these outputs can be configured via settings for FN51 and FN52.

7. THE SYSTEM TRIGGER DATA

The Alarm System saves information about the last triggers and can indicate the trigger reasons in two ways:

• a) Disarm the System, close the doors, and turn ON the ignition. The System will indicate the reason for the last trigger via direction indicator flashes (and siren signals, depending on settings).
• b) Enter FN71, FN72, or FN73. The System will indicate the reason for one of the last 3 triggers via direction indicator flashes (and siren).

Trigger Identification Table

The following table defines the reason for the trigger based on the number of flashes/signals:

Flash Count	Trigger Reason
1	Triggered built-in shock sensor
2	Triggered built-in tilt sensor
3	Triggered ultrasonic sensor (volume)
4	Triggered OM sensor
5	Ignition was turned ON
6	Front left door was opened
7	Front right door was opened
8	Rear left door was opened
9	Rear right door was opened
10	Hood was opened
11	Trunk was opened
12	Driver not identified
13	Low Batt (not used)
14	Triggered additional sensor

8. AUTOMATIC VEHICLE DETECTION

8.1. CAR DETECTION PROCEDURE

If the car was not selected manually from the list (by PC using installed GN7C Loader software, see 6), when the System is powered up, the car detection procedure is automatically activated – the System LED blinks quadruple flashes. In order for the Alarm System to identify the car in which it is installed, it is necessary to fulfill the following:

Pic. 6. Automatic car detection steps.

If the car detection procedure failed (there was no long flash of the System LED confirming the successful learning of the System), however the System detected the ignition ON and the System LED blinks double flashes, proceed as follows:

Pic. 7. Troubleshooting steps for failed car detection.

NOTES. If the Alarm System learning (automatic vehicle detection) failed:

• Repeat the procedure of automatic vehicle detection from the beginning, only this time, first turn ON the ignition and turn ON the power of the Alarm System with the ignition ON.
• Check if the CAN bus and ground wires are well connected, and whether the System is connected to the correct CAN bus.
• Update the Alarm System firmware and repeat the Alarm System learning procedure.

8.2. OTHER VEHICLE DETECTION

If the Alarm System was used in one car and later installed in another car, it is necessary to re-execute the vehicle detection procedure or select the car manually (using a computer with the installed software GN7C Loader). To start the automatic car detection procedure, follow these steps:

1. a) Enter PIN code (see 9.2).
2. b) Within 8 minutes after entering the PIN code enter the code 59 (Fn59).

8.3. IMPORTANT TO KNOW

• Vehicle detection procedure can be cancelled by Service Button press. The System terminates the detection procedure and remains in Setup Mode.
• After a successful car detection procedure the System automatically goes into Normal Mode and you can start using the System immediately.

9. MANUAL CHANGE OF THE ALARM SYSTEM SETTINGS

9.1. PIN, FN AND SN CODES

To configure the system, you will need to use the following codes:

• PIN – A 4-digit code required to activate the Setup Mode and the Service Mode.
  • Note:** The factory PIN code is printed on the Alarm System label. It is strongly recommended to change the factory PIN code after the system installation.
• FN – Function Number – A 2-digit code used to select the specific function that needs to be changed.
• SN – Setting Number – A 1-digit or 2-digit code used to select the desired setting value for the chosen function.
