Introduction
Introduction 1
The Alarm Panel
The Alarm Panel is used for sending distress alerts and showing visible and 
audible indication of incoming distress messages. Normally the Alarm Panel is 
installed at the conning position on the bridge.
The distress buttons are protected by spring loaded covers to avoid 
unintended activation of a distress alert. The distress buttons must be pressed 
for 3 to 6 seconds before the distress alert is initiated.
The Alarm Panel is supplied from 10.8 - 32 V DC. The input is protected against 
reverse polarity.
Single or Multi Alarm Panel
There are two variants of the Alarm Panel: The SAILOR 6101A and the 
SAILOR 6103A. 
• The SAILOR 6101A Alarm Panel has one distress button and can send 
distress alerts and receive information on incoming distress messages via 
the Inmarsat C satellite system only. 
• The SAILOR 6103A Multi Alarm Panel has three distress buttons and can 
send distress alerts via Inmarsat C, and distress calls via VHF and MF/HF. It 
can also receive information on incoming distress messages.
Note
In Inmarsat C GMDSS systems it is mandatory to have two distress 
buttons. If you have a Mini-C GMDSS system, only one alarm panel 
is required, because the Message Terminal, which is part of the 
system, has a distress button.

Chapter 1:  Introduction
2The AlarmPanel
SAILOR 6101A Alarm Panel
The SAILOR 6101A Alarm Panel is dedicated to Inmarsat C. It has one distress 
button for sending distress alerts over the Inmarsat C satellite network.
The display shows distress alert transmission in progress and distress alerts 
received on the Inmarsat C network.
Through the Ethernet connector you can interface to two Inmarsat C systems.
Note
If a distress alert is initiated on a system with duplicated units, only 
one of the units will send the alarm. The display shows a marker 
next to the name of the selected unit.

Introduction
SAILOR 6103A Multi Alarm Panel
The SIALOR 6103A Multi Alarm Panel connects to VHF equipment, MF/HF 
equipment and Inmarsat C equipment, and has a distress button for each type 
of system. 
The display shows distress messages received. It also indicates equipment 
type (VHF, MF/HF or Inmarsat C) when the equipment is detected by the Multi 
Alarm Panel.
Through the Ethernet connector you can interface to two Inmarsat C systems, 
two VHF systems and two MF/HF systems.
Note
If a distress alert is initiated on a system with duplicated units, only 
one of the units will send the alarm. The display shows a marker 
next to the name of the selected unit.
