Function and Role in the Alarm System

The ultrasonic sensor is responsible for monitoring the space inside the car, analyzing changes in the ultrasonic field generated within the cabin. In practice, this means that it:

• detects movement in a locked vehicle after the alarm is armed,
• cooperates with the central security module,
• helps to reduce the risk of unauthorized access to the interior,
• complements the protection provided by door and tailgate opening sensors.

Thanks to this, the Land Rover alarm system gains more complete, multi-zone protection for the passenger cabin.

Compatibility and Part Identification

The presented sensor has been designed specifically for Land Rover models, particularly the Sport L320 series, adhering to manufacturer standards. Proper fit ensures:

• consistency with the factory electrical and alarm installation,
• correct communication with the security control unit,
• the possibility of using existing mounting points in the vehicle.

For ease of selection and verification, a dedicated OEM part number and related interchangeable numbers have been used, which are detailed in the technical specifications section.

Product Characteristics and Benefits of Use

The ultrasonic alarm motion sensor in this version is a component from the Land Rover OE line, meaning it complies with the vehicle manufacturer's factory requirements. In practice, this translates to:

• maintaining the original logic of the alarm system's operation,
• stable cooperation with other security modules,
• no need for adaptation of universal solutions.

The product is offered in used condition, allowing for an economical replacement of a damaged sensor while maintaining the correct operating parameters of the system. This solution is particularly beneficial for servicing vehicles several years old, where both functionality and reasonable repair costs are important.

Installation and Service Aspects

The sensor is prepared for installation in place of the factory component, using the existing wiring harness and brackets. In a typical service scenario:

• the damaged sensor is removed from the headliner or other designated mounting location,
• the electrical installation connector is connected to the new component,
• the sensor is seated in the factory socket or bracket,
• if necessary, a test of the alarm system's operation is performed.

Due to its connection to the security system, installation by a person experienced with vehicle electrical systems is recommended to maintain full functionality and correct alarm response.
