Bridge Navigational Watch Alarm System (BNWAS) KW810. Operation: Once the MEU has been configured the cover and padlock in place the Captain is to switch the system into the required MODE and remove both the padlock and MODE selection keys and keep them in a secure place to prevent any unauthorised changes or tampering.

Bridge Navigational Watch Alarm System (BNWAS) KW810. UNACKNOWLEDGED ALARM TRANSFER sequence: The BNWAS ATI detects the UNACKNOWLEDGED alarm and enables the transfer. When the transferred unacknowledged alarm arrives, the BNWAS alert is immediately initiated at the 2 stage/OFFICER ALERT. The system then follows the alarm sequence at the (Td +30sec).

Bridge Navigational Watch Alarm System (BNWAS) KW810. RAP, WAP and DOS Units: Protection: IP65 Housing: Moulded ABS Weight: 0.2Kg Colour: Beige or Black Installing the RAP and WAP units. First decide on the location of the base assembly and mark out the location of the 2mm pilot holes.
Page 23
Bridge Navigational Watch Alarm System (BNWAS) KW810. Once the route and entry of the cables has been made, screw the base assembly to the required location and feed the cable in. Cut back the outer sheath by 10 to 15cm, if more than one unit is installed in the circuit prepare each cable and link and insulate the screen to ensure that there can be no grounding to the PCB.
Bridge Navigational Watch Alarm System (BNWAS) KW810. OAS Officer Alert Selector Interface: Remove the 4 x screw caps and screws to access the base. Make 2 holes in the base and secure the enclosure. The unit can be orientated as necessary.

Bridge Navigational Watch Alarm System (BNWAS) KW810. Mounting Remove the front cover as shown below. Cover and PCB Removal Loosen the vertical adjustment screw, slide the PCB down and remove it via the “keyhole”. Pull the PCB straight out and put it aside until required again.
Page 29
Bridge Navigational Watch Alarm System (BNWAS) KW810. For multi PIR installations, to join and complete the return of the detection loop wire use one of the spare terminals internal to the PIR e.g. TAMP alternatively another method of joining the detection return loop to ensure a continuous loop is to use an insulated butt crimp or any other similar method ensuring that the connection is insulated from the internal circuitry of the PIR PCB.

Bridge Navigational Watch Alarm System (BNWAS) KW810. Vertical Adjustment: To maintain maximum coverage range the vertical adjustment scale must be adjusted in accordance with the actual mounting height (refer to below figure). Loosen the vertical adjustment screw and slide the printed circuit board up or down until the pointer shows the actual mounting height on the scale.
