Directed Electronics 509U Ultrasonic Sensor Instruction Manual

1. Pengenalan

The Directed Electronics 509U Ultrasonic Sensor is designed to enhance vehicle security systems by detecting changes in air pressure within the vehicle's cabin. This sensor triggers an alarm when it senses an intrusion, such as a window being opened or broken, or a door being forced open, creating a pressure disturbance. It is intended for integration with compatible vehicle security systems, such as Viper and Python alarms.

2. Ciri-ciri

• Detects air pressure changes within the vehicle cabin.
• Adjustable sensitivity to prevent false alarms.
• Compatible with various Directed Electronics security systems, including Viper and Python.
• Compact design for discreet installation.

3. Kandungan Pakej

• 509U Ultrasonic Sensor Main Module
• Two (2) Ultrasonic Sensor Heads with connecting cables
• Wiring Harness (may vary based on specific kit)

4. Maklumat Keselamatan

Always disconnect the vehicle's battery before beginning any electrical installation. Ensure all wiring connections are secure and properly insulated to prevent short circuits. Consult a professional automotive technician if you are unsure about any installation steps. Improper installation can lead to vehicle damage or malfunction of the security system.

5. Persediaan dan Pemasangan

Proper installation is critical for the optimal performance of the 509U Ultrasonic Sensor. Refer to your vehicle's specific wiring diagrams and your primary alarm system's installation manual for detailed integration instructions.

5.1. Mounting the Main Module

• Choose a secure, hidden location within the vehicle's cabin, away from direct moisture or extreme heat.
• Ensure the location allows for easy access to the sensitivity adjustment dial if future adjustments are needed.
• Secure the module using screws or double-sided automotive tape.

5.2. Installing Sensor Heads

• The two sensor heads should be mounted symmetrically within the vehicle's cabin, typically on the A-pillars, near the top, angled approximately 45 degrees towards the center of the vehicle.
• Ensure the sensor heads have an unobstructed view of the cabin interior. Avoid placing them behind objects that could block sound waves.
• Route the sensor head cables carefully, avoiding sharp edges or moving parts, and connect them to the main module.

5.3. Sambungan Pendawaian

The 509U sensor typically requires the following connections:

• Power (12V Constant): Connect to a fused 12-volt constant power source.
• Tanah: Sambung ke titik asas casis pepejal.
• Input penggera: Connect the sensor's output wire to the appropriate trigger input on your vehicle's alarm system (e.g., a negative trigger input). Refer to your alarm system's manual for the correct input.

5.4. Initial Sensitivity Adjustment

• After all connections are made and the vehicle's battery is reconnected, arm your security system.
• Locate the sensitivity adjustment dial on the main module.
• Start with the sensitivity set to a low level.
• Test the sensor by simulating an intrusion (e.g., opening a window slightly, then reaching into the vehicle).
• Gradually increase the sensitivity until the desired detection level is achieved without causing false alarms from normal vehicle vibrations or external sounds.

6. Arahan Operasi

Once installed and properly adjusted, the 509U Ultrasonic Sensor operates automatically in conjunction with your vehicle's security system. When the alarm system is armed, the ultrasonic sensor becomes active. Any significant change in the air pressure within the vehicle's cabin will be detected by the sensor, triggering the alarm system.

• mempersenjatai: The sensor activates when your vehicle's alarm system is armed.
• melucutkan senjata: The sensor deactivates when your vehicle's alarm system is disarmed.
• Sensitiviti: If false alarms occur, reduce the sensitivity. If the sensor fails to detect intrusions, increase the sensitivity.

7. Penyelenggaraan

The Directed 509U Ultrasonic Sensor requires minimal maintenance.

• Periodically inspect the sensor heads and main module for any physical damage or loose connections.
• Keep the sensor heads clean and free from dust or obstructions that could interfere with their operation. Use a soft, dry cloth for cleaning.
• Avoid spraying cleaning solutions directly onto the sensor components.

8. Penyelesaian masalah

8.1. Penggera Palsu

• Sensitiviti Tinggi: Reduce the sensitivity setting on the main module.
• Windows Left Down: The sensor is designed to work in a sealed cabin. Leaving windows open will cause false alarms due to external air movement.
• Loose Objects: Ensure there are no loose objects inside the vehicle that could shift and create air disturbances.
• Improper Mounting: Verify that sensor heads are securely mounted and not vibrating.

8.2. Sensor Not Triggering Alarm

• Sensitiviti Rendah: Increase the sensitivity setting on the main module.
• Pendawaian yang salah: Check all power, ground, and alarm input connections for proper installation and secure contact.
• Obstructed Sensors: Ensure the sensor heads have a clear line of sight within the cabin.
• Unit Rosak: If all other troubleshooting steps fail, the sensor unit may be defective. Contact customer support or a professional installer.
