4. Setup and Installation
Installation of the BEEPER XR5-TX1 is designed to be straightforward and typically takes around 15 minutes. Follow these steps:
- Connect the Siren Unit: The siren unit requires only two connections: a red wire to the 12V permanent positive (+) terminal of the vehicle battery and a black wire to the negative (-) or ground terminal of the vehicle battery.
- Position the Infrasonic Sensor: Place the infrasonic sensor into the vehicle's cigarette lighter socket. This sensor connects wirelessly to the main siren unit.
Ensure all connections are secure and the siren unit is mounted in a safe, discreet location within the engine bay or vehicle interior.

5. Operation
The BEEPER XR5-TX1 offers both manual and automatic operation modes.
5.1 Remote Control Functions
The two included remote controls allow for manual control of the alarm system.
- Activation / Deactivation: Use the designated buttons to manually arm or disarm the alarm.
- Panic Mode: A dedicated button on the remote can trigger the alarm instantly in an emergency.

5.2 Automatic Activation (Hands-Free Access)
The system can automatically arm and disarm based on the proximity of the remote control:
- Arming: The alarm will automatically arm within 30 seconds when the remote control moves approximately 15 to 20 meters away from the vehicle.
- Disarming: The alarm will automatically disarm when the remote control is within approximately 10 meters of the vehicle.

5.3 Infrasonic Sensor Operation
The infrasonic sensor detects changes in air pressure inside the vehicle, such as when a door is opened or a window is broken. This sensor is wirelessly connected to the main unit.
- Activation/Deactivation: The sensor can be individually activated or deactivated.
- Sensitivity Adjustment: The sensitivity of the infrasonic sensor can be adjusted to suit your preference and environment.

6. Maintenance
To ensure optimal performance of your BEEPER XR5-TX1 alarm system, consider the following maintenance points:
- Remote Control Batteries: The remote controls are powered by two CR2032 flat batteries (included). Replace them when the remote's range or responsiveness decreases.
- Infrasonic Sensor Charging: The infrasonic sensor recharges via the cigarette lighter socket. It has an autonomy of approximately 6 days when not connected to the cigarette lighter. Ensure it is periodically charged to maintain its functionality.
7. Troubleshooting
If you encounter issues with your BEEPER XR5-TX1 alarm system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm is oversensitive and triggers frequently. | Infrasonic sensor sensitivity set too high. External vibrations (e.g., loud vehicles, strong winds). | Adjust the sensitivity of the infrasonic sensor to a lower setting. Refer to the sensor's instructions for specific adjustment procedures. |
| Alarm triggers randomly without apparent cause. | Faulty sensor, low battery in remote or sensor, interference. | Check and replace remote control batteries. Ensure infrasonic sensor is charged. If problem persists, contact support. |
| Remote control not responding. | Low or dead remote control batteries. Out of range. | Replace the two CR2032 batteries in the remote control. Ensure you are within the operational range (approx. 10m for disarming). |
| Alarm does not arm/disarm automatically. | Remote control not carried with user. Interference. | Ensure the remote control is with you when approaching or leaving the vehicle. Check for strong radio interference in the area. |
