Hardwired vehicle tracker

Teltonika FMM13A

A compact, hardwired LTE Cat M1 tracker with internal antennas and a backup battery. It reports position, and because it has configurable inputs, analog inputs and outputs, it can also read a fuel sensor or door switch and switch a relay - the unit we fit when a vehicle or trailer needs more than a dot on a map.

What it does

Reports when the power is cut

A 170 mAh backup battery keeps the unit reporting if the vehicle battery is disconnected, and an unplug alert is raised, so a tampered or stolen vehicle does not simply go quiet.

Inputs and outputs for more than location

Three digital inputs, two analog inputs and three digital outputs, including a negative input and two impulse inputs. That is how it reads a fuel sensor, a door or PTO switch, or an auxiliary signal, and how it can drive a relay.

Fuel and engine data

Supports analog fuel level sensors and several CAN adapters, with engine RPM available for ignition detection through a CAN adapter. Without one, ignition is detected from the accelerometer or from the supply voltage.

Reads Bluetooth sensors

Bluetooth 4.0 LE lets it pick up temperature and humidity sensors, an OBD-II dongle or a barcode scanner, and send the readings back with the position.

Alerts and driver behaviour

Over-speed, excessive idling, harsh driving, towing, crash and unplug detection are built in, along with manual and automatic geofences and trip recording.

Updated without a site visit

Firmware and configuration update over the air, so a change to reporting behaviour across a fleet does not mean touching every unit.

Where it is suited

This is a hardwired unit for the inside of a cab or a trailer. It is rated IP41, which is protection against dust and dripping, not against rain or washing, so it is installed in a dry place rather than exposed outdoors. It is Cat M1 only, with no 2G fallback, so it relies on LTE-M coverage where it operates.

Light and heavy-duty vehicles
Trailers that need door or sensor monitoring
Vehicles with a fuel sensor to read
Rental and leased vehicles
Vehicles that need an immobilizer or relay output

Common questions

Can it go outside on a trailer?

It can be fitted to a trailer, but inside a protected spot. The case is IP41, so it is not sealed against rain or washing. If the unit has to sit exposed to the weather, the Teltonika TAT141 is the sealed outdoor choice.

What happens if the vehicle battery is disconnected?

It keeps reporting on its internal 170 mAh backup battery for a time and raises an unplug alert. The backup battery is there to report the event, not to run the unit for days.

Does it have a 2G fallback?

No. It is an LTE Cat M1 unit only. Where Cat M1 coverage is thin, a unit with 2G fallback, such as the TAT141 or the FMM880, will hold on to a signal better.

Can it read a fuel sensor?

Yes. It has analog inputs for a fuel level sensor and supports several CAN adapters. Fuel reading depends on the sensor and the vehicle, so tell us what you run and we will confirm what it can read before we quote.

What does it work with for Bluetooth?

It reads Bluetooth 4.0 LE devices, including temperature and humidity sensors and an OBD-II dongle. Tell us what you need to measure and we will confirm which sensors suit.
