Cobra 3865 Manual Exclusive Today
Includes a wireless or wired backup battery siren that activates if cables are cut or the main power is disconnected.
Triggers if any door, the hood (bonnet), or the trunk (boot) is opened while armed.
Fix these to the top of the A-pillars (pointing toward the rear window) or C-pillars (pointing toward the windshield).
For optimal security, all components should be placed in hidden, difficult-to-access locations.
Mount the main unit inside the cabin, far from heat sources, with the main connector facing downward to prevent moisture buildup.
Allows the driver to disarm the system manually via a dashboard-mounted push button if the remote fails. Installation Guide & Procedures
Uses intelligent ultrasonic sensors to monitor the interior cabin for movement.
Connect to the vehicle's 12V battery and negative ground. Ensure the black antenna wire is not connected to anything, as this would reduce the transmitter's range. Operating Instructions How A Cobra Alarm Works
