TIFFIN MOTORHOMES –ALLEGRO BUS® Chapter 7 ELECTRICAL FEATURES
Multiplex System
Your motor home features a 12 VDC multiplex system (Figure 7-13). This
system allows the ability to control circuits from multiple locations in the coach.
Each switch allows you to turn a circuit on or off with individual button presses
and provides an indicator light to tell you the status of the circuit (i.e. whether it
is on or off). Many of the circuits are also dimmable by simply holding the
button to dim up or down.
Additional features of the multiplex system include the following:
• Master Feature (this is only on the control panel located at the entrance door)—this allows you to turn all lighting
circuits on or off with the press of a single button that is labeled “Light Master.” Pressing the Light Master “off”
switch will turn off all the interior lights within the coach. Momentarily pressing the Light Master “on” switch will turn
on the same circuits that were on when Light Master “off” was pressed. Light Master “off” remembers which lights
were on when the switch was pressed and will turn those same lights back on when the Light Master “on” is
momentarily pressed. Holding the Light Master “on” switch will turn on all interior light circuits.
• Switch Panel Back Lighting—all of the switches are backlit to make the labels easy to read. If you desire to turn the
panel lights off, a switch is conveniently located at the center of the coach labeled “Panel Lights” which allows you
to turn the back lighting On, Off, or Dim.
• Status LED Indicator—a green LED beside each switch indicates whether the load is on or off. In some cases, certain
switches such as Awnings, Compartment Locks, and Generator do not have a status indicator at the switch.
• Dimming Circuits—certain circuits within the coach are dimmable. To dim a light down, simply hold the “off”
switch until the light is at the desired level and release the switch. This setting will be remembered the next
time the circuit is turned on. To adjust the light up, simply hold the “on” switch until the light is at the desired
level and release the switch.
• Timed Cargo Light Feature—when the cargo lights are turned “on,” they will automatically turn off within 14
minutes to prevent battery run down.
In the event that you have to check fuses, the centralized control panel is located in the third passenger side bay.
The fuses for the different light circuits are located here. The status of a fuse for any circuit can be easily
identified by looking at the circuit number and coordinating the number to the proper listing on the fuse list
chart beside the centralized control panel.
If a circuit is on and the fuse is blown, the indicator light beside that fuse will be red. If the circuit is on and the
fuse is good, the indicator light beside that fuse will be green. If the circuit is off, the indicator light beside that
fuse will not be on.
