Why Do I Get a Power Cut-Off Alarm When the Device Wasn't Unplugged?

Sometimes, a power cut-off alarm may be triggered even if you didn’t manually disconnect the device. Here are the common reasons:

1. Loose or Intermittent Wiring

If the power cable is not securely connected, vibration from the road, bumpy terrain, or poor installation can cause a momentary loss of power — just enough to trigger the alarm.

2. Vehicle Battery Voltage Drops

When the vehicle battery voltage drops too low (e.g., during cold starts or long periods of inactivity), the GPS tracker may detect this as a power loss.

3. Ignition Off for Extended Time

In some installations, when the ignition is turned off for a long time, the power to the GPS device may be cut off intentionally by the vehicle’s system, triggering an alert.

4. Internal Protection Circuit

Some GPS trackers have built-in protection features that shut down the device when voltage or current drops below safe levels. This safety mechanism can look like a power disconnection to the system.

5. Temporary Power Spike or Dip

Fluctuations in the vehicle’s electrical system — such as when starting the engine — can cause a brief power dip, which may be interpreted as a disconnection.

How to Reduce False Alarms?

Make sure the GPS tracker is installed by a professional with secure and stable wiring.

Avoid DIY connections to unstable or low-quality power sources.

Ask your installer to use a constant power line instead of ACC-only if frequent false alarms occur.
