The Cobra 3865 is a Thatcham Category 2-1 insurance-approved car alarm system designed as an upgrade for vehicles already equipped with a factory immobilizer. It is primarily recognized for its seamless integration with the vehicle's original remote control. Key Features & Performance
Perimeter Protection: Monitors all doors, the boot, and the bonnet; opening any of these while the system is armed triggers a 30-second acoustic and visual alarm.
Ultrasonic Interior Protection: Uses intelligent volumetric sensors to detect movement inside the cabin. This can be manually disabled (e.g., if leaving a pet inside) by pressing the remote's large button twice during arming.
Security Diagnostics: A dashboard LED provides status updates. Rapid flashing upon return indicates the alarm was triggered in your absence, and the number of blinks can identify which sensor was activated (e.g., 2 flashes for ultrasonic, 3 for bonnet).
Safety Overrides: Includes an emergency override feature using a personalized PIN code if the original remote is lost or fails. Installation & Technical Specifications
Hardware Design: Features a mini modular design, making it easier to hide components within the vehicle dashboard or engine bay.
Cable Protection: Includes cable-cutting protection; if the battery is disconnected or wires are cut, the backup battery siren will automatically trigger.
Central Locking: Can be wired to operate the vehicle's central door locking (CDL) system, supporting up to 5-wire configurations. Operating Voltage: Standard DC 12V ± 3V. Reliability & Maintenance
