Remote Immobilization Mechanics
Dynamic Speed Interlock
Firmware algorithms prevent engine cut-off execution when vehicle speed exceeds 20 km/h, protecting transmission components and driver control.
External Relay Architecture
Connects to a standard 12V/24V automotive relay rated up to 40A to safely interrupt fuel pump, ignition coil, or starter motor circuits.
Command Transmission Channels
Accepts remote triggers via TCP/IP data packets over cellular networks or encrypted fallback SMS text commands.
Execution Status Feedback
Returns immediate confirmation logs reporting relay activation state and circuit continuity to the monitoring server.
Wiring and Hardware Integration
Four-Wire Core Harness
Color-coded leads for Red (Power Positive 9V-90V), Black (Ground), Yellow (Ignition ACC), and White (Digital Output).
Transient Voltage Suppression
Integrated TVS diodes absorb electrical load dumps up to 100V, protecting internal circuits from alternator spikes.
Concealed Low-Profile Housing
Compact form factor allows discreet mounting under dashboards, inside engine bays, or behind vehicle trim panels.
High-Vibration Connectors
Industrial-grade locking molex connectors prevent terminal loosening during heavy-duty and off-road operation.
Vehicle Fleet Compatibility
Light Passenger Vehicles
Direct 12V system compatibility for sedans, SUVs, and delivery vans.
Commercial Heavy Trucks
Native 24V system support without external voltage reducers for semi-trucks and transit buses.
Off-Road Heavy Machinery
Withstands wide electrical margins across excavators, loaders, and agricultural tractors.
Electric Commercial Fleets
Low quiescent power draw prevents auxiliary 12V battery drain in parked battery-electric vehicles.
Operating Safety and Limitations
Speed Threshold Safety
Halts remote immobilization commands if real-time speed sensors exceed safety thresholds.
Cranking Voltage Management
Regulated internal power management maintains processor stability during low-voltage engine cranking down to 6V DC.
Thermal Overload Throttling
Protects internal cellular amplifiers and microcontrollers when ambient temperatures exceed +75C.
Network Disconnection Memory
Retains last-known immobilization state in non-volatile flash memory during cellular signal loss.

Frequently Asked Questions
Q: How does the speed interlock prevent accidents during remote engine cut-off?
A: The microcontroller checks real-time speed data before energizing the relay. If speed exceeds 20 km/h, the cut-off command is queued until the vehicle slows down safely.
Q: Can this tracker connect directly to a vehicle fuel pump?
A: Yes. The output wire drives an external automotive relay that controls the high-current fuel pump circuit, isolating the tracker from high electrical loads.
Q: What tracking protocols are supported for server integration?
A: The device supports standard communication protocols used by major fleet management software platforms, enabling direct TCP/IP point-to-point connection.
Q: What is the minimum order quantity for custom firmware and logo printing?
A: OEM customization options, including firmware modifications and casing logo printing, are available for orders starting at 500 units.
Q: How does the device handle power loss if the main battery is disconnected?
A: The internal 150mAh backup battery instantly powers the unit to transmit a tamper alert and final GPS position packet before entering emergency beacon mode.
