SeaNet-Alarm Users Manual
When will alarms be set/reset
SeaNet-Alarm listens to the SeaTalk Bus for coming or going alarm conditions.
Instrument alarms – like shallow water, high wind speed etc. - have to be set and enabled
in the SeaTalk instrument.
The Alarm output is activated when :
–
An instrument newly sets the appropriate alarm on the SeaTalk Bus
–
AND this alarm type is enabled in SeaNet-Alarm.
( see Page 14)
–
AND the Alarm is active longer than delay time set in SeaNet-Alarm ( If delay time is
set )
(see Page 13)
The Alarm output is reset when :
–
An Instrument clears the appropriate alarm on the SeaTalk Bus
–
OR the acknowledge button on SeaNet-Alarm is pressed
–
OR alarm duration time, set in SeaNet-Alarm, is expired
(see Page 14)
An alarm will be retriggered if the appropriate alarm is
reset
on the SeaTalk Bus and later
set
again.
If an alarm stays active on the seatalk bus and the alarm output is switched off by the
acknowledge button or timeout, this alarm will only be retriggered after it has disapperared
on SeaTalk and reappeared later.
A „SeaTalk instrument failure“ alarm is triggered, when an instrument ( like depth,
windspeed etc.) has sent data to the Seatalk network, and than suddenly stops sending
data.
It is not possible to announce two or more alarms at the same time.
If two or more alarms are active at the same time, the first one will be announced.
When the currently announced alarm is acknowledged – by pressing the pushbutton or
because it's alarm time has exired – the next alarm be announced.
If a second alarm comes and goes while the first alarm is still active, this second alarm will
never sound.
