How FMC130 Immobilisation Works
The FMC130 controls immobilisation via its digital output (DOUT1). When a command is received from the fleet management platform, the FMC130 activates or deactivates DOUT1, which in turn opens or closes a relay wired into the vehicle's starter circuit. When the relay is open, the starter circuit is interrupted and the engine cannot be started.
The immobilisation command is sent over the 4G mobile network to the device. The device must have an active SIM card, mobile network coverage and a connection to the fleet platform for the command to be received and executed.
What You Need
- Teltonika FMC130 with DOUT1 wired and accessible
- A normally closed (NC) or normally open (NO) automotive relay — confirm the correct relay type for your wiring configuration
- Relay socket and wiring harness
- Inline fuse for relay power supply
- Vehicle wiring diagram (specific to make, model and year)
- Multimeter for circuit testing
- Teltonika Configurator software on a laptop
- Fleet management platform with remote command capability
- A qualified auto electrician for installation
Safety Rules — Read Before You Start
Remote immobilisation must be implemented with strict safety controls. Failure to follow these rules can result in dangerous situations, vehicle damage or legal liability.
- Never cut fuel or ignition while the vehicle is moving. Immobilisation must only prevent the engine from starting — it must not shut down a running engine.
- Wire the relay to the starter circuit only — not to the ignition, fuel pump or any safety-critical system.
- Only activate immobilisation when the vehicle is confirmed stationary. Most fleet platforms allow you to verify vehicle speed before sending the command.
- Ensure the relay fails safe. If the FMC130 loses power or the relay fails, the vehicle should default to a driveable state to avoid stranding the driver in a dangerous location.
- Professional installation by a qualified auto electrician is essential. Incorrect wiring can damage the vehicle's electrical system or create safety hazards.
Relay Wiring for Immobilisation
The relay acts as an electrically controlled switch in the vehicle's starter circuit. When the FMC130 activates DOUT1, it energises the relay coil, which opens or closes the relay contacts depending on whether you use a normally closed (NC) or normally open (NO) configuration.
Recommended Configuration: Normally Closed (NC) Relay
A normally closed relay is the recommended approach for vehicle immobilisation:
- In its default (unpowered) state, the relay contacts are closed — the starter circuit is complete and the vehicle can start normally.
- When the FMC130 activates DOUT1, the relay coil is energised, the contacts open, and the starter circuit is broken — the vehicle cannot start.
- If the FMC130 loses power or the relay fails, the vehicle defaults to startable — preventing the driver from being stranded.
Basic Wiring Steps
- Identify the starter signal wire in the vehicle using the wiring diagram — this is typically a wire from the ignition switch to the starter motor relay
- Cut the starter signal wire and connect each end to the NC relay contacts (COM and NC terminals)
- Connect the relay coil terminals to the FMC130 DOUT1 output and to vehicle ground
- Add an inline fuse on the relay coil power supply
- Mount the relay in a protected location away from heat and moisture
Confirm exact wiring with the vehicle's wiring diagram and the relay's datasheet. Relay wiring varies by vehicle make and model. Always have a qualified auto electrician perform or verify the installation.
Connecting the Relay to the FMC130 DOUT1
The FMC130's DOUT1 is an open-collector output. It does not supply voltage directly — instead, it provides a ground path when activated. To drive a relay coil:
- Connect one side of the relay coil to a fused 12V supply (constant power)
- Connect the other side of the relay coil to DOUT1 on the FMC130
- When DOUT1 is activated, it pulls the relay coil to ground, energising the relay
Confirm the DOUT1 current rating and output specifications with the latest Teltonika FMC130 product documentation before connecting any relay. Exceeding the output current rating can damage the device.
Configuring Immobilisation in Teltonika Configurator
Once the relay is wired, configure the FMC130 to control DOUT1 for immobilisation using Teltonika Configurator:
- Connect the FMC130 to your laptop via USB and open Teltonika Configurator
- Navigate to the I/O section
- Locate DOUT1 settings
- Set the DOUT1 default state to match your relay configuration (high or low — confirm with Teltonika documentation)
- Enable remote control of DOUT1 via SMS or GPRS command — this allows the fleet platform to send immobilisation commands
- Configure any automatic immobilisation rules if required (e.g., immobilise if ignition is off for more than X hours in a geofence breach scenario)
- Save and write the configuration to the device
Configuration options vary by firmware version. Always refer to the latest Teltonika FMC130 configuration guide on the Teltonika Wiki for current settings and parameter names.
Testing the Immobilisation Function
Before deploying the vehicle, test the immobilisation function thoroughly:
- Park the vehicle in a safe, open area with the engine off
- Confirm the vehicle starts normally with immobilisation inactive
- Send the immobilise command from the fleet platform or via SMS (if configured)
- Confirm the FMC130 acknowledges the command (check the fleet platform for confirmation)
- Attempt to start the vehicle — it should not start
- Send the de-immobilise command
- Confirm the vehicle starts normally again
- Test the fail-safe: disconnect the FMC130 power and confirm the vehicle can still be started (NC relay configuration)
Document the test results and keep a record for your fleet maintenance log.
Sending the Immobilise Command from Your Fleet Platform
The method for sending an immobilisation command depends on your fleet management platform. Most platforms that support Teltonika devices provide a remote command interface. Common methods include:
- Platform web interface — select the vehicle on the map and send a remote output command
- SMS command — send a configured SMS command directly to the device's SIM card number (confirm command syntax with Teltonika documentation)
- GPRS command — sent automatically by the platform based on a trigger rule (e.g., geofence breach, theft alert)
Contact your fleet platform provider for platform-specific immobilisation command instructions. Techtonika Autolink can advise on compatible platforms and configuration.
Australian Fleet Use Cases
Theft Prevention and Recovery
For Sydney and Melbourne fleet operators, vehicle theft is a real operational risk. The FMC130 immobiliser allows fleet managers to remotely prevent a stolen vehicle from being restarted after the thief stops — significantly improving recovery chances when used in conjunction with real-time GPS tracking and police notification.
Car Rental Businesses
Car rental operators across Australia use remote immobilisation to manage overdue returns, enforce geographic restrictions and recover vehicles from customers who have not paid. The FMC130 allows the rental operator to immobilise the vehicle remotely once it is confirmed stationary, without requiring physical intervention. See FMC130 for Car Rental Businesses for more detail.
Construction Equipment and Plant Vehicles
Construction companies in Queensland, Western Australia and New South Wales use immobilisation to prevent unauthorised use of expensive plant vehicles and work trucks outside of approved hours or locations. Combined with geofencing, the FMC130 can automatically flag after-hours movement and allow the manager to immobilise the vehicle remotely.
Tradie and Small Business Vehicle Protection
For sole operators and small businesses, a stolen work vehicle means lost income and tools. The FMC130 immobiliser provides an additional layer of protection beyond standard vehicle security systems, giving the owner the ability to act quickly if theft is detected.
Legal and Privacy Considerations in Australia
Remote vehicle immobilisation is a powerful capability that must be used responsibly and lawfully.
- Employee vehicles: If immobilisation is installed on vehicles driven by employees, staff must be informed of the capability as part of your vehicle tracking and monitoring policy. Seek legal advice on your obligations under applicable Australian privacy and workplace laws.
- Customer vehicles (car rental): Immobilisation terms should be clearly disclosed in the rental agreement. Activating immobilisation on a moving vehicle is dangerous and must never occur.
- Safety first: Never activate immobilisation unless the vehicle is confirmed stationary. Always verify vehicle speed on the fleet platform before sending the command.
- Liability: Techtonika Autolink does not provide legal advice. Consult a qualified legal professional regarding your obligations before deploying remote immobilisation in a commercial context.
Limitations
- Immobilisation requires mobile network coverage — commands cannot be received in areas without 4G or 2G signal
- The device must be powered and connected to the fleet platform to receive commands
- A determined thief may be able to bypass a relay-based immobiliser with sufficient time and knowledge — immobilisation is a deterrent, not an absolute security guarantee
- Incorrect relay wiring can prevent the vehicle from starting even when immobilisation is not active — professional installation is essential
- Confirm all DOUT1 specifications and command syntax with the latest Teltonika documentation
Frequently Asked Questions
Can the FMC130 immobilise a vehicle while it is moving?
The FMC130 can technically receive an immobilisation command at any time, but the relay is wired to the starter circuit — not the ignition or fuel system — so it prevents the engine from being restarted, not from running. You must never attempt to shut down a moving vehicle. Always confirm the vehicle is stationary before sending the command.
What relay should I use with the FMC130?
A standard 12V automotive relay rated for the starter circuit current is typically used. A normally closed (NC) relay is recommended for fail-safe operation. Confirm relay specificat
