Remote Control Logic
Speed-Gated Interruption: Software protocols verify vehicle speed telemetry prior to fuel cut execution, preventing high-speed shutdowns.
Controlled Deceleration: Executes fuel cut by pulsing circuits only when vehicle velocity drops below 20 km/h.
Instant Restoration: Supports encrypted SMS and server-issued commands to immediately re-enable ignition circuits.
Tamper Detection: Triggers emergency alerts upon unauthorized disconnection of main power leads or antennas.
Wiring and Installation
Color-Coded Harness: Standard multi-core wiring with dedicated leads for Power, Ground, Ignition detection, and Relay control.
Relay Integration: Connects to an external 12V/24V 40A automotive relay wired in series with starter or fuel pump control lines.
Compact Footprint: Dimensions measure 85mm x 45mm x 15mm for discrete placement behind dashboards or within interior trim.
Diagnostic LEDs: Multi-color indicators display real-time GNSS fix, cellular registration, and power status.
Vehicle Compatibility
Light Vehicles: Fully compatible with 12V DC electrical systems in passenger cars, SUVs, and delivery vans.
Heavy Transport: Supports direct connection to 24V DC architectures in semi-trucks and construction machinery.
Electric Fleets: Operates within high-voltage auxiliary power domains of hybrid and battery-electric commercial vehicles.
Ignition Sensing: Supports both analog ignition signals and intelligent voltage-threshold detection.
Safety and Operating Limits
Inductive Suppression: Integrated flyback diodes across relay control lines absorb voltage spikes from switching motor coils.
Surge Protection: Internal transient voltage suppression diodes clamp high-energy electrical noise from vehicle alternators.
Velocity Lockouts: Firmware automatically inhibits immobilization commands when vehicle speed exceeds preset highway limits.
Fail-Safe Memory: Retains last-known relay state during cellular network dropouts to prevent unintended stalling.
OEM Customization Parameters
Protocol Adaptation: Custom binary protocol development matching server parsing requirements with OTA update support.
Enclosure Branding: Laser-etched serial numbers, barcode labeling, and molded logo options for OEM identification.
Interface Expansion: Optional RS232 or 1-Wire configurations for RFID driver identification and fuel sensors.
Production Metrics: Minimum order quantity of 500 units with lead times averaging 25 to 35 business days.

Regulatory Compliance: Manufactured under ISO 9001 standards with CE, FCC, and RoHS certifications.
Frequently Asked Questions
Q: What happens to the cut-off state if cellular signal is lost?
A: The device retains its last commanded relay state in non-volatile memory, executing safety logic to prevent action while moving.
Q: Can the relay output drive a fuel pump directly?
A: No. The internal output sinks a maximum of 500mA, requiring an external automotive relay for high-current circuits.
Q: What is the standby power draw when the engine is off?
A: In deep sleep mode, power consumption drops below 5mA at 12V DC.
Q: How are custom communication protocols integrated?
A: Engineering teams provide full protocol documentation and developer SDK support for direct socket integration.
Q: What are the lead times for samples versus bulk production?
A: Sample evaluation units ship within 3 business days, while bulk manufacturing orders require 25 to 35 business days.
