GN7C Installation Manual

The GN7C is an advanced alarm system with built-in sensors, specifically designed for vehicles equipped with a CAN bus and a 12V battery system. The system is controlled via the original remote key FOB or Keyless Entry System.

1. Security & Installation Guidelines

The system unit must be installed inside the passenger compartment in a location that is difficult to access.
Installation should be in a place free from moisture and corrosive elements.
Keep the unit away from heat-emitting elements and sources of electromagnetic interference, such as vehicle computers, fans, or relay blocks.
To prevent condensate accumulation, avoid mounting the unit directly onto metal parts.
The unit should be positioned so that the wire connectors exit from the bottom side.
Avoid placing wires near moving or hot parts of the vehicle.

2. Technical Specifications & Circuit Limits

Circuit / Component	Maximum Allowed Current / Specification
Cut-off circuit (A)	25 A
Indicator relay (K2)	2 x 21 W
Siren output	2 A
Optional control No. 1	0.13 A
Optional control No. 2	0.13 A
Direction indicators (Left/Right)	7 A each
Operating Voltage	9-15 V DC [cite: 531]
Average Current Consumption	<20mA (12V) [cite: 531]
Operating Temperature	-40 to +85 °C [cite: 531]

3. System Configuration and PC Setup

System parameters must be configured using a computer before finalizing the installation:

Software: Use the GN7C Loader or Firmware Upgrade Tool[cite: 536].
Connection: Connect the unit via a Micro-USB cable[cite: 531].
Vehicle Selection: Select the specific vehicle model and modification from the internal database containing over 800 models[cite: 531].
Procedure: Choose the car, set the CAN bus modification (e.g., mod 1), enable CAN bus control, and save settings to the device.

4. Wiring and Connectivity

The system utilizes several connectors for integration:

7-pin Connector: Used for the Secret Button (for PIN entry) and System LED.
CAN Bus Interface: Requires connection to CAN_H and CAN_L lines for data communication with the vehicle.
Indicator Control: Supports multiple diagrams (A through E):
- Option A: Fully controlled via CAN bus.
- Option B/C: Connected to the Hazard Warning Button with either CAN or analog monitoring.
- Option E: Direct control via the internal relay.

5. Operational Features and Indicators

Automatic Detection: Upon power-up, the system can automatically detect the vehicle type, indicated by quadruple LED flashes.
Trigger Identification: After disarming, the LED flashes to indicate the last trigger reason:
- 2 flashes: Shock sensor
- 3 flashes: Tilt sensor
- 4 flashes: Ultrasonic (volume) sensor
- 6 flashes: Ignition ON
- 7-10 flashes: Door opened
- 11 flashes: Hood opened
- 13 flashes: Driver identification failure
Security Modes: Includes Service/Valet mode, Anti-Hijack mode, and Silent Arming options[cite: 536].

6. PIN Code and Manual Settings

The factory PIN code is found on the system label.
Setup Mode: Active for 8 minutes after PIN entry, allowing manual adjustments via the Secret Button or Ignition Key.
Emergency Override: The PIN code can be used to disarm the system or enter Service Mode if the remote is unavailable[cite: 536].
