Product Description

・
The built–in alarms include depth alarm, bottom–missing alarm
*
1
, power failure/low
voltage alarm and power removal/shutoff alarm.
・
The depth alarm alerts the operator to decreasing depth (shallow alarm). A variable
depth marker can be turned on to set the alarm depth graphically as well as digitally.
・
The bottom–missing alarm
*
1
warns against the bottom echo being lost, becoming too
weak or exceeding the current range limit.
・
The power failure/low voltage alarm will be activated if the power line voltage drops
below the factory–specified predetermined level.
・
The power removal/shutoff alarm will be triggered in the event power is accidentally
removed or shut off at the ship’s power source with the equipment operating, emitting
continuously a repeating beep for several minutes.
・
The alarm activation status, except for the power removal/shutoff alarm, will be
indicated both audibly and visually, and the alarm on/off switched outputs will be
separately available for driving externally connected alarm indicating devices through a
devoted connector.
・
For bridge al
ert
management (BAM) purposes, the equipment outputs the IEC
61162–1 Ed. 5 (2016) format alert–related sentences, or optionally the NMEA–0183
(IEC 61162–1 Ed. 4)
–format alarm sentences, for each alarm via the rear–panel
RS–422–A/B
and
I/O
serial interface ports at specified intervals.
・
When any of the alarms becomes active, the output’s status and intervals will be
changed accordingly, and the active alarm can be remotely acknowledged and reset
with an appropriate software command from an INS/BAM terminal or can be manually
acknowledged with a suitable hardware on/off switch mounted at a convenient, different
location.
・
Previously delivered units already installed on–board can be updated through the
authorized dealers to comply with the IEC 61162–1 Ed. 5 communications protocol
standard regarding the bridge–centered alarm handling procedure.
・
The display cabinet has a built–in switch–mode regulator–based efficient DC power
supply that assures reliable operation against a wide range of voltage fluctuations.
・
In an installation where an AC power source is available, the equipment can be
operated primarily from the AC source through an optional
Model AC–2000
AC adapter
for an automatic changeover to the DC power source in the event of AC power outage.
