12-Volt Operation

The only thing you have to do is make sure the house
battery does not run down� In normal usage this
shouldn't be a problem since you would normally be
plugged into an external AC power source at night or
when camping� When you're plugged into shoreline
power or running the generator the inverter/charger
charges the battery and carries much of the load�
Some nights you may not find a place to plug into
city power� This should not be a problem; you can
comfortably run your lights, water pump, and vents in a
normal fashion without depleting the battery�
If you are not plugged into city power, and you plan
on staying longer than a day or two, you'll want to
conserve your battery by using as few lights and
appliances as possible� Check the monitor system
regularly� If you notice the lights becoming dim, it's
much easier on the battery if you start the generator or
run the chassis engine before the battery runs down�
The generator starts from the house battery� If the
house battery becomes depleted, the chassis engine
can be started to charge it� It should only take a few
minutes before the generator will start�
The engine battery and house battery are isolated from
each other by a battery separation system, preventing
the two systems from drawing down simultaneously�
They will connect through the system if charging from
the engine, generator, or inverter/charger is detected

Multiplex System

The Multiplex System provides advanced automation
and mobile electrical solutions for your touring coach�
Firefly is a multiplex network system designed to
combine multiple signals across a media to reduce
wires and simplify end user control� The system
combines all desired functions and controls of the
touring coach into a central location� Regional control
panels are installed to operate specific areas.
The switch panels conveniently located throughout the
touring coach allow you to turn your lighting on or off,
as well as, the ability to dim lighting to a desired level
with the touch of a button� Each button is illuminated,
when it is pressed, indicating the circuit is either ON or
OFF� The button will turn white when the circuit is OFF
and blue when it is ON�
5-8
NOTE
Buttons that are controlling circuits such as Light
Master and Panel Lights typically Do Not change
from blue to white.
The Light Master button allows you to instantly turn
ON or OFF all lighting in the interior of your touring
coach� Pressing the Light Master ON button will turn
on only the lights that were on when Light Master OFF
was pressed� Holding the button ON for more than 1
second will turn on all the interior lighting�
NOTE
Pressing the Light Master ON after the Light Master
OFF button has been held or pushed twice will
result in no response. Hold ON to resolve.
NOTE
When dimming it is normal for LED lights to flicker.
Lights should return to normal once they are set to
a desired brightness.
