Product overview
Description
ACC401 is a portable compact 4G Cat.1 GPS tracker for tracking and monitoring automobiles, motorcycles, electric two-wheelers, and other types of transportation whose voltages range from 9V to 90V. It has a built-in GPS antenna with good RX capabilities for precise position fixes. It can offer optional TTL interfaces. The 4G capability enables it to be widely used in different countries and regions. The black appearance makes the ACC401 easy to hide on a vehicle. It can fix positions in real-time, generate tracks of traveled routes, send out alerts for exceptions, help immobilize vehicles by cutting off fuel and power supply, and other functions, making it a suitable choice for businesses trying to lower their management risks, protect the vehicles from theft.

Features
- Real-time Tracking
The positioning accuracy could reach under 10m under open sky. - Power-cut Alert
An alert will be triggered if the power supply to the device is disconnected or its power cable has been cut. - Tamper Alert
An alert will be triggered if the device is removed.
Driving Behaviors
- Harsh Acceleration
The device will report a harsh acceleration event to the platform when it detects the vehicle’s speed increases abruptly due to a hard stepping on the accelerator. - Harsh Braking
The device will report a hard braking event to the platform if it detects the vehicle’s speed decreases abruptly. - Sharp Cornering
The device will report a harsh turn event to the platform if it detects the vehicle is cornering sharply during moving. - Collision
The device will report a collision event to the platform if it detects the vehicle in motion collides with another object or vehicle. - Low External Power Alert
If the device detects the voltage of the external power is under the preset threshold, it will send out an alert message. - Low Internal Battery Alert
If the device detects that thee voltage of its internal battery is lower than the preset threshold, it will send out an alert message. - Geofence Alert
Provided that you have set a geofence and the alert conditions on the designated platform, you will be alerted if the device detects the vehicle enters or leaves the geofence and the alert conditions are met. - Speed Alert
Provided that you have set the speed limit for the vehicle on the platform or via SMS, you will be alerted if the device detects the vehicle moves at a speed greater than the speed limit for a set duration. - Vibrating Alert
If the device detects any vibration when the vehicle stops and has its ignition off, it will send out an alert.
Installing the Device
Device check
Check visually whether the device is in good condition and whether the relevant accessories are complete.
SIM Card Attachment
- Prepare a proper SIM card. For size details, refer to the following figure.
- Insert the SIM card (power off the device before inserting or removing the SIM card) as the following figure shows:
After the SIM card is inserted in place, slide the battery switch to ON.
Note: The SIM card should be inserted correctly. Make sure the SIM has data services activated and is not in arrears. Disconnect the external power and slide the battery switch to OFF before inserting or removing the SIM card. After the SIM card is placed in the slot, slide the battery switch to ON and lock the SIM.
Wiring Diagram for Motorcycles and Electric Two-Wheelers
- Use a multimeter to determine the positive and negative wires of the battery.
- Use the multimeter to determine the ACC wire. Provided the black and red probes of the multimeter are connected with two wires separately, if the multimeter reads 0V when the key points to OFF and reads the same as the supply voltage of the vehicle when the key points to ON, then the wire connected by the red probe of the multimeter is the ACC wire.
- Connect the red wire (positive) of the device power cable with the positive pole of the motorcycle battery.
- Mate the connectors as the following figure shows.

Note: If the device is installed under the rider, the strength of satellite signals reaching the device will be seriously affected.
Wiring Diagram for Automobiles
- Use a multimeter to determine the positive and negative wires of the battery.
- Use the multimeter to determine the ACC wire. Provided the black and red probes of the multimeter are connected with two wires separately, if the multimeter reads 0V when the key points to OFF and reads the same as the supply voltage of the vehicle when the key points to ON, then the wire connected by the red probe of the multimeter is the ACC wire.
- Connect the red wire of the device power cable to the positive pole of the vehicle battery.
- Mate the connectors as the following figure shows.
Note:
- Choose accessories specified by the manufacture.
- The standard supply range is 9–90V, please use the original power cable and ensure that the positive and negative ends are correctly wired.
- Description on device installation
To ensure that the device is installed and debugged correctly, professional agencies and personnel designated by your dealer are recommended. See the following figure for install positions:
Possible Install Positions for Automobiles
Note:
- Make sure the front side of the device is facing to the sky;
- Avoid positions where a metal insulation layer or heating layer may
exist; as such a layer may affect the strength of satellite signals reaching the device.

FAQ
Q: How do I set up geofence alerts?
A: To set up geofence alerts, you need to define a geofence area and set alert conditions on the designated platform. You will receive alerts if the vehicle enters or leaves the geofence and meets the alert conditions.
Q: How can I receive low external power alerts?
A: If the device detects that the voltage of the external power is below the preset threshold, it will send out an alert message to notify you.
