SafetyMOB
Wireless kill cord - emergency stop
Every year there is several serious boating accidents where the driver falls overboard and the kill
cord has not been used.
If you fall overboard there is a great risk that the boat automatically turns and you get run over, or it
continues straight ahead while maintaining speed.
The SafetyMOB system consists of a helm unit attached to the life jacket or the driver and a boat
unit that is mounted in the boat and connected to the boat's existing emergency stop. The helm
unit communicates constantly with the boat unit, if you fall overboard the communication is
interrupted and the engine stops.
It is possible to set the system in low speed (fishermans) mode, this will increase the time until the
engine is stopped if the communication is interrupted, so you have time to move closer to the boat
unit to regain communication. The internal buzzer will ‘chirp’ to indicate loss of radio
communication.
After the system is triggered for man overboard, the engine can be restarted by switching off the
SafetyMOB system and after that start the engine as usual. If you have forgotten to bring the helm
unit you can run the boat as usual, the system is not activated until a helm unit are in close
proximity to the boat unit on startup.
The SafetyMOB system works on both outboard and inboard engines, gasoline and diesels with
electronic stop.
Power consumption
The boat unit has a power consumption of about 10mA. The helm unit has a battery life of at
least one year. When the boat trip is over the helm unit will automatically go into low power
mode.
Radio communication
The units is communicating several times per second via the free 2.4 GHz ISM band. The
communication is unaffected by radio signals from mobile phones and VHF.
When the radio communication is interrupted the emergency stop is activated in about 4
seconds in normal mode and about 20 seconds in low speed mode.
Ease of installation
Installing a SafetyMOB boat unit is relatively easy and can be performed by "DIY".
The boat units cabling for emergency stop is connected in parallel or in series with the existing
emergency stop. The boats existing emergency stop will continue to function as normal. If low
speed mode is going to be used a switch must be connected to designated wires. It is also
possible to connect an external relay, this can be used for instance to stop an electric motor
(trolling motor).
The boat unit is preferably mounted close to the steering wheel so that the distance to the driver is
minimized, this makes the system less sensitive to radio interference.

Electrical connections
Emergency stop - kill cord#
The boat units cabling for emergency stop is connected in parallel or in series with the existing
emergency stop depending on whether it is a short-circuit or breaking-up emergency stop.
How do I know witch emergency stop my boat is equipped with?
One can easily find out witch type of emergency stop the boat is fitted with.
1. Start the engine as usual, to verify that everything works as it should.
2. Stop the engine. Locate the cables to the kill switch - emergency stop.
3. Cut off one cable. NOTE ensure that cable stub is long enough that it is possible to connect it to
the SafetyMOB boat unit.
4. Try to start the engine, if it is possible, you probably have a short-circuit emergency stop, ie
shorting the wires together will stop the engine. Try to activate your existing emergency stop, the
engine should continue to run.
If you are unable to start the engine, you probably have a breaking-up emergency stop, ie the
emergency stop breaks up the connection to the engine when activated.
If you have a short-circuit emergency stop, connect both cables to the boat unit. Cut the second
cable to the existing emergency stop (NOTE ensure that cable stub is long enough that it is possible
to connect it to the SafetyMOB boat unit) and connect the two cables to the boat unit cables marked
NO and C (the boat unit is now connected in parallel with the existing emergency stop).
If you have a breaking-up emergency stop, connect the boat unit cable marked NC to one end of the
cut cord and C to the other end (the boat unit is now connected in series with the existing
External relay#
An external relay can be connected to the WHITE ( EXT ) wire and +12V, max load 1A /12V. This
signal ( EXT ) is grounded when the emergency stop is activated. This can be used for instance to
stop an electric motor (trolling motor). This function is latching, even if the communication is
restored the EXT signal will be activated.
Normal/low-speed mode switching
It is possible to connect a switch to the BLUE ( MODE ) wire and +12V to select between normal and
low speed mode. When the circuit is closed the system is in low speed mode, when open in normal
mode. Leave the BLUE wire unconnected if this function is not used.
External buzzer
It is possible to connect an external buzzer to the ORANGE ( BUZ ) wire and ground. Max 100mA/
12V. This buzzer will mirror the internal buzzer.

System Startup
When SafetyMOB is started you hear 2 ‘chirps’ from the boat unit to indicate that the system is
active and has synchronized with a registered helm unit. If no ‘chirps’ is heard during the first
10 seconds you should give the helm unit a little shake to ensure that it is transmitting. If this
does not help, but you hear a single ‘chirp’ about 30s after startup the system has not found
any registered helm unit, you can now choose to register a helm unit or continue to run the
boat without an active system.
Low battery warning for helm unit
When the battery level of the helm unit is low, the system indicates this by after startup ‘chirp’
10 times with 6 seconds between each ‘chirp’. When the first battery warning is heard there is
about 4 weeks of power left in the battery but it should be changed as soon as possible.
If the batteries run down during operating of the boat the motor will be stopped once. After
that stop just start the engine again and continue. One can now use the boat as usual but the
SafetyMOB system will not be active. The system is not activated until a helm unit with a
working battery is nearby at startup.
New helm unit
If you lost the helm unit you can register a new one by re-configure the system as above.
Battery replacement in the helm unit
Unscrew the top part of the helm unit and replace the battery with a new one. The battery type
is CR2032.
System configuration - register helm unit
When deploying a new system, the helm unit must be recognized by the boat unit. Pushing the
button on the boat unit will start the search for helm units. To ensure that the helm unit is
transmitting you should give it a shake. When the boat unit ‘chirps’ 2 times a helm unit has been
registered and the system is ready for use. The registered helm unit is stored in non volatile
memory. This procedure is only necessary when you must register a new helm unit to the system.
If an indicator light is connected it will be lit to indicate that the system is active.
