Distress Alert
Initiating a Distress Alert
The Distress Alert function can be activated using the DISTRESS button on the LT-3110S Control Unit or
from the DISTRESS button on the LT-3150S Alarm Panel. The procedure for activating the Distress Alert
function is the same for both buttons:
1.
Lift the red lid marked DISTRESS
2.
Press and hold the red DISTRESS button for minimum 3 seconds
(a distress tone will be played immediately when pushing the DISTRESS button)
3.
The Distress Alert function will be activated in the LT-3100S GMDSS system after 3 seconds
–
indicated by distress tone stopping
4.
Hereafter you can release the red DISTRESS button
(the light in the red button is now on maximum intensity)
IMPORTANT:
After activating a Distress Alert from an external LT-3150S Alarm Panel it is recommended
to check the status of the Distress Alert by verifying the display information of the LT-3110S
Control Unit, where more information will be available.
The Distress Alert function will preempt any other ongoing service (voice or data) of priority lower than
distress.
Placing a voice call of distress priority
After the Distress Alert message has been acknowledged by the Iridium network, the system will
automatically place a voice call of priority distress to the configured preferred RCC if the “auto
-
dial” setting
is enabled.
A voice call of priority distress can be placed to the preferred RCC any time after the Distress Alert message
has been acknowledged by the Iridium network. If the “auto
-
dial” setting is enabled, a voice call of priority
distress is automatically placed after acknowledgement has been received. To manually place a voice call,
press the Call RCC soft key, press the off-hook key or off-hook the handset.
Selecting Nature of Distress
The Nature of Distress can be assigned at any time before (MENU -> GMDSS -> Distress Alert Setup ->
Nature of Distress) or after (soft key Select Nature / Update Nature) activation of Distress Alert.
