Interface description
4.4 Alarm relay
The SAILOR 6282 AIS Transponder has an internal alarm relay. Connect the alarm relay to
an audible alarm device or the ships alarm system, if available.
The ship’s alarm system is connected to the alarm relay through the SUB-D 50 pin
connector, which is connected to the SAILOR 6283 AIS Connection Box and Wall Tray or
the multi-wire cable included. See the section SUB-D50 connector and cable on page 3-14
for a description of the connector and the cable. The alarm relay connections are described
in the table below.
When the SAILOR 6282 AIS Transponder is powered on and there are no alarms the relay is
energized, i.e. ALARM COM and ALARM NO is connected.
The maximum switching current is 1 A.
The maximum switching voltage is 125 VAC, 60 VDC.
4.5 Low power forced control (gas alarm) 1 W
The transmitter output power of the SAILOR 6282 AIS Transponder is normally 12 W. For
the vessel type defined as Tanker(s) and the voyage data set to Moored the transmitter
output power will automatically be reduced to 1 W.
The transmitter can be forced to an output power of 1 W. This is done by shorting the '1W'
signal to DC-.
The Low power forced control (gas alarm) 1W can be connected to a switch to DC- through
the SUB-D 50 pin connector, which is connected to the SAILOR 6283 AIS Connection Box
and Wall Tray or the multi-wire cable supplied with the SAILOR 6282 AIS Transponder. See
the section SUB-D50 connector and cable on page 3-14 for a description of the connector
and the cable.
