List of suitable vehicles
FMS500 Light+ is intended for all vehicles with petrol or diesel engines, where negative pole is
body of the vehicle. Device must be connected to the vehicle battery, ensuring constant power supply
even if the engine is not working and ignition is off.
When active, FM Light+ uses a small amount of direct current (DC) – less than 50 mA at 12V. It
can be mounted in 12 V or 24 V vehicles.
Standby mode
This is a mode of the device when the vehicle ignition is turned off, and there are no active alarms.
In this mode, the GPS receiver is switched off in the control unit (in order to reduce power
consumption) and communication with the server intervals are increased. Device switches to active
mode if programmed trigger is detected (for example accelerometer signal).
Active mode
This is a mode when ignition is on, or when any programmed trigger is active. In this mode, GPS
receiver is enabled in the central unit and connection with the server is carried out more frequently.
After ignition is switched off, the central unit remains active for another 10 minutes.
Free configuration of data dispatch frequency is possible.
During the data transfer (GSM / GPRS communications), short-term increase in current
consumption of up to 100 mA is possible.
Power-line (primary or back up battery) has to be connected via 1A fuses.
Basic instructions before beginning the installation
Quality of connections, location of the device, etc. play a significant role on accurate operation of
the system. Below are some tips and rules for correct installation to attain professional quality and
ensure maximum efficiency of the device.
Location for central unit installation
Central unit should be hidden in a difficult to access location to prevent unwanted interference by
unauthorized persons. Small size and flat body makes it easy to do and allows use of small gaps for
installation.
