1 Preface

To the Owner

Thank you for purchasing Totem Plus Bridge Navigational Watch Alarm System (Totem BNWAS). Totem

BNWAS is a state of the art maritime product derived from a sophisticated technology that was developed in

Totem Plus. This manual provides the general layout, operation, installation, and maintenance of Totem

BNWAS.

What is BNWAS?

Safety of navigation is the greatest concern for shipping industry. The purpose of the BNWAS is to monitor bridge

activity and detect operator disability which could lead to marine accidents. The system monitors the awareness

of the Officer Of the Watch (OOW) and automatically alerts the Master or another qualified OOW if for any reason

the OOW becomes incapable of performing the OOW’s duties.

Watch Alarm prevents possible collisions or incidents related to the watchman fell asleep or incapacitated.

At the heart of the system is a microcontroller inside the I/O Unit. This unit is interfaced with Main Unit, Reset

Units, Alarm Units, Motion Detectors and external equipment.

The design and construction of the system is in accordance with IMO resolutions:

* Up to 10 additional Wing Reset Units can be installed as additional bridge visual indications, audible alarms, and remote audible alarms. The reset button will be blocked in this case.

2.2 Functional Description

The Totem BNWAS system is designed to automatically monitor duty personal activity by following: 1) motion

detectors located strategically around the bridge area 2) OOW operation on the bridge systems capable of

registering physical activity and mental alertness of the OOW (modern radars, ECDIS etc.) 3) reset buttons

located at the bridge working stations.

Should the bridge be left unattended or if the Officer Of the Watch (OOW) becomes incapacitated, the BNWAS

system alerts the OOW in the bridge through visual alarm followed by an audio alarm (First stage alarm). Master

and/or other qualified navigating officers would be alerted if OOW is not responding (Second stage alarm).

If none of the personnel has pressed the Reset button, the system will activate the alarms units in every

navigator's cabin and public areas (Third Stage alarm). See time diagram below (Figure 2).

Reset Buttons around the bridge can be also used for making an Emergency Call. The call will be transferred to

the Second stage immediately and to the Third stage according to the time diagram.

In a port the system can be set to act as a conventional movement detector in order to increase security

measures.

Figure 2: Alarm Sequence


of 51 Version 1.6

Once operational, the watch alarm function remains dormant for a Td period of between 3 and 12 min by setup.

At the end of this dormant period, the alarm system initiates a visual indication on the bridge by flashing light of

all reset buttons. If Reset is not pressed 15 seconds (0.25 of minute) after the visual indication is initiated,

BNWAS will sound a first stage audible alarm on the bridge by activating buzzer synchronized with flashing light.

If the First stage is not reset, BNWAS activates a Second Stage remote visual and audible alarm at the Backup

Officer location (according to setup) 15 seconds after the first stage audible alarm is initiated (0.5 minute after

end of dormant period). If the Second Stage is not reset after 90 seconds to 3 minutes (by setup) after the

second stage alarm is initiated, the system additionally activates the third stage remote visual and audible alarm

at the locations of more crew members that are capable of taking corrective actions (all Officers cabins and Public

Area).

2.2.1 Operation Modes

2.2.1.1 Auto Mode

BNWAS is activated if Autopilot/Track control system is ON and deactivated if Autopilot/Track control system is

OFF. The automatic switch performed by input status connected to relevant Heading/Track control system.

2.2.1.2 Manual Mode

BNWAS is operational regardless of Autopilot/Track control system status.

2.2.1.3 Off Mode

Watch function is not active. Emergency call is possible.

2.2.1.4 Security Mode

When just turned ON the system delays Security mode activation by 30 seconds. The time is given to leave the

bridge without triggering an alarm. During the delay the system gives beep sounds with longer last beep when

activated. If during Security mode a motion detected on the bridge the system triggers bridge alarm and transfers

it automatically to the second stage according to back-up officer setup on the Main Unit. If after 90 seconds to 3

minutes (by setup) nobody reset the system the third stage bridge alarm is activated.

2.2.1.5 Emergency Call

Emergency call can be activated by any of BNWAS reset buttons installed on the bridge including wings and Main

Unit. The OOW can activate the Emergency call by pressing and holding any button for 2 seconds. The call will

be immediately transferred to the second stage alarm (to the backup officer according to the setup of the

system) and if no reset in due time (according to setup) to the third stage (to all officers and public area). A short

press on any reset button will cancel the emergency call and start next dormant period.

4.7.2 Auto Pilot On

When the system is in Auto mode the On status of the input automatically brings the system to operation

and inhibits it when Off status is set. Contact closure output should be provided by ship’s heading or track

control system. The Auto mode is not suitable for use on a ship conforming with SOLAS V 19.2.2.3 which

requires BNWAS to be in operation whenever the ship is under way at sea. To avoid accidental deactivation,

in this case the input should be short circuit to 24V on the terminals. For connection use external I/O signals

connection electrical drawings below.

4.7.3 System Fault and Power Failure Outputs

System and Power Fault outputs provided to repeat fault indication on a central alarm panel if fitted. The

output circuit is an optocoupler. Optimal load is 3 mA. Maximum load is 50 mA. For right connection polarity

should be observed.

4.7.4 RS485 Output for VDR

RS485 output provides an interface according to IEC 61162-1 for VDR or another registering system. There

are terminals for two systems to be connected simultaneously. For connection use external I/O signals

connection electrical drawings below.

ALR sentence is in use with the following message content:

$BNALR,hhmmss.ss,xxx,A,A,c--c*hh<CR><LF>

– hhmmss.ss: this part left blank (zero field)

– xxx: alarm ID. In BNWAS is designated as "000"

– A: A =Dormant period exceeded

V =Dormant period not exceeded

– A: A =Alarm acknowledged

V =Alarm unacknowledged

–c --c: BNWAS mode :c 1 ;c 2 ;c 3

c 1 =AUT or MAN or OFF

c 2 =Dormant period in min,(03 –12)

c 3 =Alarm stage:1,2 or 3.


of 51 Version 1.6

Example: $BNALR,,000,A,V,AUT;03;1*hh<CR><L F>

The alarm message shall be sent with any change of the BNWAS settings for mode or dormant period, and

with any activated and reset alarm. For communication control BNWAS should send “heart beat” every 3

minutes where Stage field replaced by “L” = “alive”.

Example:

$BNALR,,000,A,V,AUT;03;L*hh<CR><L F>

4.8 AC and DC power supply

24VDC or 115/220 VAC (optional) from ships mains serves as main power supply for BNWAS. Provision of

24VDC from battery maintained ships supply source is required as battery back-up power supply for BNWAS

and has to be connected. For connection use Power Supply Connections electrical drawings below.

Identify the Origin of the problem Remedy

Have you tried to restart the System? Remove AC and DC power for 3 seconds and put it back

for system reset

Is the differential voltage of serial

signals within the IEC 61162

specification? (Should be minimum 2V)

If the output differential voltage is less than 2V check or

steady change Controller

Does it work with a different serial input

of VDR? (Use a port what you know is

working.)

If the port does work with, use a spare serial port, if

available, or replace the serial card

Is there interference?

1. Is the cable shielded and the cores

are twisted?
