• When an OLAS transmitter goes out of range an alert will sound on the OLAS N2K hub and any
connected MOB alert devices.
• The OLAS N2K control switch will go red and if connected to the vessel’s stop system the stop
switch will be activated for 7 seconds. This is normally sufcient time for the engine to stop.
• After 7 seconds the stop switch is deactivated, and the engine can be started again allowing a
rescue to be performed.
• Press the control switch once to acknowledge the alarm and the OLAS N2K hub will revert to Paused
state. Tracking is now paused until the OLAS transmitter is recovered.
• Once the OLAS transmitter is back on the vessel and within 1 metre of the OLAS N2K tracking will
automatically start again.
• Alternatively, to manually activate tracking again press the control switch once and tracking will start
again, if the OLAS transmitter is within 1 metre of the OLAS N2K hub.
NOTE: Pause will remain active if the OLAS transmitter that was lost is not back within 1 metre of the OLAS
N2K hub.
The OLAS N2K can continue to be used as an MOB alarm system when an OLAS transmitter is not being
used.
Whilst the OLAS N2K is connected to a NMEA 2000 network if any other devices on the same network
transmit an MOB alert message, the OLAS N2K will react. The OLAS N2K hub will alert, the OLAS mobile
app will alert and the OLAS CONNECT devices (if attached) will alert.
• If no OLAS transmitters are in range the OLAS N2K will beep multiple times every minute and the
control switch will ash red and green.
• To silence the beeping press the control switch for 2 seconds.
• The control switch will continue to ash red and green. The OLAS N2K is still operating and looking
for OLAS transmitters.
• If an OLAS transmitter is moved into range the OLAS N2K will double beep and start normal tracking.
• If a MOB alert is triggered on the NMEA 2000 network or via the OLAS CONNECT all OLAS N2K
MOB alerts will be activated.
a. Detection Time (seconds) - adjusting the detection time allows a period of time where an OLAS
transmitter can reconnect silently, preventing any alert from occurring. This may be preferable on
larger vessels with multiple cabins where there is an increased chance of signal being blocked.
b. Alert Delay (seconds) – adjusting the alert delay time changes the amount of time the operator has
before the MOB alert and relay is activated. This may be preferable on larger vessels where there
is increased chance of signal being blocked. During the ‘Alert Delay’ period an alert will sound to
indicate signal has been lost. During this period if the control switch is pressed it manually overrides
the cut-off for 30 seconds allowing the OLAS transmitter to be brought back into range.
i. Select the menu tab in the top left-hand corner of the home screen (3 lines).
ii. Select ‘Alert Settings’.
iii. Use the slider to select the ‘Detection Time’ or ‘Alert Delay’ period.
