The BNWAS should incorporate the following
operational modes:
- Automatic (Automatically brought into
operation whenever the ship’s heading
or track control system is activated and
inhibited when not activated)
- Manual ON (In operation constantly)
- Manual OFF (Does not operate under
any circumstances)
Once operational, the alarm system should
remain dormant for a period of between 3
and 12 min (Td).
At the end of this dormant period, the alarm
system should initiate a visual indication on
the bridge.
If not reset, the BNWAS should additionally
sound a first stage audible alarm on the
bridge 15 s after the visual indication is
initiated.
If not reset, the BNWAS should additionally
sound a second stage remote audible alarm
in the back-up officer’s and/or Master’s
location 15 s after the first stage audible
alarm is initiated.
If not reset, the BNWAS should additionally
sound a third stage remote audible alarm
at the locations of further crew members
capable of taking corrective actions 90 s
after the second stage remote audible alarm
is initiated.

62616:2010 - 3.1.3.2
In vessels other than passenger vessels, the
second or third stage remote audible alarms
may sound in all the above locations at the
same time. If the second stage audible alarm
is sounded in this way, the third stage alarm
may be omitted.
In larger vessels, the delay between the
second and third stage alarms may be set
to a longer value on installation, up to a
maximum of 12 min, to allow sufficient time
for the back-up officer and/or Master to
reach the bridge.
It should not be possible to initiate the
reset function or cancel any audible alarm
from any device, equipment or system not
physically located in areas of the bridge
providing proper look out.
The reset function should, by a single
operator action, cancel the visual indication
and all audible alarms and initiate a further
dormant period. If the reset function is
activated before the end of the dormant
period, the period should be re-initiated to
run for its full duration from the time of
the reset.
To initiate the reset function, an input
representing a single operator action by
the OOW is required. This input may be
generated by reset devices forming an
integral part of the BNWAS or by external
inputs from other equipment capable of
registering physical activity and mental
alertness of the OOW.

A continuous activation of any reset device
should not prolong the dormant period
or cause a suppression of the sequence of
indications and alarms.
Means may be provided on the bridge
to immediately activate the second, and
subsequently third, stage remote audible
alarms by means of an Emergency Call push
button or similar.
The alarm system should be capable of
achieving the timings stated in section 4.1.2
with accuracy of 5% or 5 s, whichever is less,
under all environmental conditions.
The means of selecting the Operational
Mode and the duration of the Dormant
Period should be security protected so that
access to these controls should be restricted
to the Master only.

Means of activating the reset function
should only be available in positions on the
bridge giving proper look out and preferably
adjacent to visual indications. Means of
activating the reset function should be easily
accessible from the conning position, the
workstation for navigating and manoeuvring,
the workstation for monitoring and the
bridge wings.
The operational mode of the equipment
should be indicated to the OOW.
The visual indication initiated at the end of
the dormant period should take the form
of a flashing indication. Flashing indications
should be visible from all operational
positions on the bridge where the OOW may
reasonably be expected to be stationed. The
color of the indication(s) should be chosen
so as not to impair night vision and dimming
facilities should be included.
The first stage audible alarm which sounds on
the bridge at the end of the visual indication
period should have its own characteristic
tone or modulation intended to alert, but
not to startle, the OOW. This alarm should be
audible from all operational positions on the
bridge where the OOW may reasonably be
expected to be stationed. This function may
be engineered using one or more sounding
devices. Tone/modulation characteristics
and volume level should be selectable during
commissioning of the system.

The remote audible alarm which sounds in the
locations of the Master, officers and further
crew members capable of taking corrective
action at the end of the bridge audible alarm
period should be easily identifiable by its
sound and should indicate urgency. The
volume of this alarm should be sufficient for
it to be heard throughout the locations above
and to wake sleeping persons.
All items of equipment forming part of the
BNWAS should be tamper-proof so that no
member of the crew may interfere with the
systems operation.
Reset devices should be designed and
installed so as to minimize the possibility
of their operation by any means other than
activation by the OOW. Reset devices should
all be of a uniform design and should be
illuminated for identification at night.
Alternative reset arrangements may be
incorporated to initiate the reset function
from other equipment on the bridge capable
of registering operator actions in positions
giving proper look out.
The BNWAS should be powered from the
ship’s main power supply. The malfunction
indication, and all elements of the Emergency
Call facility, if incorporated, should be
powered from a battery maintained supply.

5 WEEE Directive:
The WEEE Directive aims to both reduce the amount of electrical and electronic
equipment being produced and to encourage everyone to reuse, recycle and recover it.
The WEEE Directive also aims to improve the environmental performance of businesses
that manufacture, supply, use, recycle and recover electrical and electronic equipment.
The NavWatch as is exempt from the WEEE directive as any equipment that is installed on
a fixed Installation is exempted.
Notice to European Union Customers
The crossed-out wheeled bin symbol above on the Battery indicates that this equipment
has been put on the market after 13 August 2005, and is included in the scope of the
directive 2002/96/EEC on waste electrical and electronic equipment (WEEE) and of the
national decree(s) which transpose provisions of such directive.
At the end of its lifetime, this device can only be disposed of in compliance with the
provisions of the above mentioned European directive (and following possible revisions)
as well as with the corresponding national regulation. Severe penalties are possible for
unauthorized disposal.
Electrical and Electronic Equipment (EEE) may contain polluting components and
hazardous substances which accumulation could pose serious risk for the environment
and human health.
That’s why local Administrations provide regulations which encourage reuse and
recycling, and prohibit the disposal of WEEE as unsorted municipal waste and require
the collection of such WEEE separately (at specifically authorized treatment facilities).
Manufacturer and authorized distributors are required to supply information about a safe
treatment and disposition of the specific device.
You may also return this equipment to your distributor when purchasing a new one. As
for reuse and recycling, notwithstanding the limits imposed by the nature and the use
of this device, the manufacturer will do his best to develop recovery processes. Please
contact the local distributor for information.
