The GT 800/1/2/3 is an advanced auto alarm system designed to provide comprehensive security for vehicles. This user and installation manual outlines its functions, features, and maintenance procedures, ensuring proper setup and operation. The system is engineered to integrate seamlessly with various vehicle types, offering both basic and advanced protection against theft and unauthorized access.
Function Description
The primary function of the GT 800/1/2/3 alarm system is to deter theft and alert the owner to potential security breaches. It achieves this through a combination of sensors, an immobilizer, and visual/acoustic signals.
- Arming and Disarming: The alarm system can be armed and disarmed using the vehicle's original remote control handset or door key lock. When armed, it provides a range of protections. Disarming the system typically involves a visual and acoustic signal to confirm the action.
- Engine Immobilization: A core security feature, the engine immobilizer prevents the vehicle from being started when the alarm is armed. This is achieved by cutting the ignition switched live wire to critical components like the fuel pump relay or solenoid valve, depending on the vehicle type. For vehicles with a transponder immobilizer, this connection may not be necessary.
- Perimeter Protection: The system monitors the vehicle's doors, bonnet, and boot through pin switches. If any of these are opened while the alarm is armed, it will trigger an alert. The system can also stabilize impulsive signals from switches/discriminators, ensuring reliable detection.
- Volumetric Protection: An ultrasonic sensor is included to detect movement within the passenger compartment. This sensor can be adjusted for sensitivity to prevent false alarms while ensuring effective interior monitoring.
- Power Supply Tamper Protection: The alarm is designed to detect if its power supply wires are cut while armed, triggering an alert. For enhanced security, the GT 800/2 model includes a self-power supply feature with a rechargeable backup battery, allowing the siren to operate even if the main power is disconnected.
- Anti-Hijack Function: This feature provides an additional layer of security, particularly in situations where the driver might be forced out of the vehicle. When activated, it can immobilize the vehicle after a certain period if the driver's door is opened, preventing the vehicle from being driven away by an unauthorized person.
- Electric Windows Closing Command: For vehicles equipped with a "comfort" function, the alarm can automatically close electric windows when armed. If the vehicle lacks this function, an additional module may be required.
- Visual and Acoustic Signals: The system provides clear feedback through visual signals (vehicle indicators) and acoustic signals (siren beeps) during arming, disarming, and alarm triggers. These signals can be programmed to suit user preferences.
- Status Check LED: A flashing LED on the dashboard provides visual feedback on the alarm's status and can indicate the cause of a previous alarm trigger through a sequence of flashes, helping to diagnose potential issues.
- Emergency Disarming: In situations where the original remote control fails (e.g., due to a discharged battery), the system can be disarmed using a "GT CARD CODE" and a specific procedure involving the LED button.
Usage Features
The GT 800/1/2/3 is designed for user-friendliness while offering a high level of customization.
- Programmable Functions: The system allows for the modification of several functions to tailor its operation to specific vehicle requirements and user preferences. These include:
- Self-coding vehicle indicators impulses number: Adjusts the number of indicator flashes during arming and disarming.
- Switches/Discriminators signals stabilizer: Enables recognition of impulsive signals from switches.
- Memorisation of switches/discriminators signals only after actuator signals: Determines if switch signals are recognized only after actuator signals.
- Memorisation of actuator signals of changeable type: Allows for the recognition of changeable actuator impulse switch signals.
- Anti-hijack door signal stabilizer: Stabilizes impulsive signals from the anti-hijack door switch.
- Acoustic signal when arming/disarming: Enables or disables audible beeps during arming/disarming.
- Visual signal when arming/disarming: Enables or disables indicator flashes during arming/disarming.
- Courtesy light switching on when disarming: Activates the courtesy light for 15 seconds upon disarming.
- Self-Coding for Door Lock/Unlock Signals: The system features a self-coding procedure to learn the vehicle's original door lock and unlock signals, ensuring seamless integration with the central door locking system. This process involves earthing a specific wire and operating the vehicle's remote control.
- Rapid Test Function: After installation, a rapid test procedure allows the installer to verify the correct operation of all connected sensors and functions, including additional sensors, door/bonnet/boot switches, ultrasonic sensors, and the anti-hijack button. This helps ensure the system is fully functional before handover to the user.
- Isolation of Sensors: Users can temporarily isolate additional sensors and the ultrasonic sensor when arming the alarm, which is useful in specific situations (e.g., leaving pets in the car). This is done by pressing the LED button before arming.
- Anti-Hijack Activation/Deactivation: The anti-hijack function can be reserved or disabled by pressing the dedicated anti-hijack button, providing flexibility based on the user's security needs.
- Clear Feedback: The system provides distinct visual and acoustic signals for different events, such as arming, disarming, alarm triggers, and status checks, making it easy for the user to understand the system's state.
Maintenance Features
The GT 800/1/2/3 is designed for reliability, with some features contributing to its long-term performance and ease of troubleshooting.
- Rechargeable Backup Battery (GT 800/2): For models equipped with self-power supply, the rechargeable Nickel-Cadmium battery ensures continuous protection. The siren recharges when the alarm is disarmed and the ignition key is on for approximately 16 hours, maintaining readiness.
- Status Check LED for Diagnostics: The flashing LED on the dashboard is a crucial diagnostic tool. By observing the sequence of flashes after an alarm trigger, the user or installer can identify which sensor caused the alarm, aiding in troubleshooting and maintenance.
- Periodic Functions Check: It is recommended to periodically check all functions of the alarm system to ensure it remains in optimal working condition. This proactive approach helps identify and address any potential issues before they compromise security.
- Professional Installation and Support: The manual emphasizes that the alarm system should be mounted by a professional installer, ensuring correct wiring and configuration. For activating or deactivating specific functions (like visual and acoustic signals during arming/disarming), contacting a professional installer is advised, ensuring proper system integrity.
- Warranty Conditions: The product comes with a 24-month warranty, covering defects in manufacturing. This encourages proper installation and provides recourse for users in case of system malfunctions, highlighting the manufacturer's commitment to quality.
- Robust Design: The alarm is designed to operate within a wide temperature range (-40 °C to +85 °C) and is placed in the engine compartment, away from direct water spray and high-tension wiring, contributing to its durability and reliability in various environmental conditions.
- Solder and Isolate Connections: The installation instructions stress the importance of soldering and isolating all connections, which is a critical maintenance practice to prevent electrical shorts, corrosion, and ensure long-term reliability of the wiring.
