6-4.3.2 Emergency lighting. If the servicing power system fails, the emergency power system automatically keeps
emergency lights (white fluorescent and red Incandescent) lit. As soon as the failure occurs, the 24 Vdc battery bank on
top of the deckhouse supplies power to the inverter. The Inverter changes the 24 Vdc power to 120 Vac and supplies the
emergency panel.
A green (Barge 1) or blue (Barges 2 and 3) light on the switchboard Indicates that emergency power from the 24 Vdc
battery bank is available for emergency lighting in the event of power failure. When the circuit breakers listed below are
closed, emergency lights can be turned ON or OFF by activating any of the four ON/OFF toggle switches. One switch is
near the green (Barge 1) or blue (Barges 2 and 3) light, one near the dayroom starboard door, one near the ROWPU
space port door, and one near the ROWPU space starboard door.
a.
ROWPU space. ROWPU space white lights circuit breaker 10P13A-1 and ROWPU space red lights circuit
breaker 10P13A-3 on emergency lighting panel (Figure 6-8).
b.
Dayroom. Workshop, dayroom white lights circuit breaker 10P13A-2 and workshop, dayroom red lights circuit
breaker 10P13A-4 on emergency lighting panel.
c.
Workshop. Workshop, dayroom white lights circuit breaker 10P13A-2 and workshop, dayroom red lights circuit
breaker 10P13A-4 on emergency lighting panel.
d.
Voids. Voids 1 and 2 white lights circuit breaker 10P13A-5 and voids 3, 4, and 5 white lights circuit breaker
10P13A-6 on emergency lighting panel.
e.
During operation checks. Perform operation checks in paragraph 6-4.3.1.e.
6-4.4 Shutdown procedures
6-4.4.1 Normal lighting
a.
Turn ROWPU space fluorescent lights OFF by opening (OFF) circuit breaker 2P13-1 thru 2P13-4 on deck lighting
panel (Figure 6-6).
b.
Turn dayroom fluorescent lights OFF by operating either of the rotary snap switches in the dayroom or by opening
circuit breaker 2P13-6 on deck lighting panel.
c.
Turn workshop fluorescent lights OFF by operating rotary snap switch in workshop or by closing circuit breaker
2P13-5 on deck lighting panel.
d.
Turn fluorescent lights in the voids OFF by opening circuit breakers 3P13-1 thru 3P13-8 on void lighting panel
(Figure 6-7).
6-4.4.2 Emergency lighting. To turn all emergency lights OFF (fluorescent and red), operate any of the four emergency
light toggle switches, circuit breakers, Inverter, or inverter circuit breaker.
Section III. Exterior lighting system
6-5 Description. The exterior lighting system provides lighting for navigation, night operations, and lighting on the
weatherdeck. The system's arrangement is shown in Figure 6-9, and its components are listed in Table 6-3.
6-6 Description of operation. Power is provided to the exterior side lights, floodlights, and searchlights by either service
generator, the auxiliary generator, or shore power. Exterior side lights are operated from bulkhead-mounted rotary
switches located In the ROWPU space. Floodlights are also operated from bulkhead-mounted rotary switches.
Searchlights are operated from base-mounted rotary switches.
Power is provided to the shore discharge hose deployment status lights, anchor light, and navigation lights by the 24
Vdc power panel. All of these lights are operated by closing circuit breakers on the 24 Vdc power panel.
