IRIS – Infrared
Information
System
The IRIS system consists of simple
infrared transmitters and receivers
(transceivers). One transceiver is
mounted on the vehicle. Another
transceiver is mounted at the loca-
tion (or locations) where the vehicle
owner wants to extract information,
such as the entrance to the shop
or the fuel island. IRIS provides a
wireless connection between vehi-
cle systems and off-board PC soft-
ware applications.
Optimized Idle
®
Optimized Idle is an engine con-
trolled management tool that auto-
matically starts and stops the
engine based on:
■ Battery Voltage
■ Engine Temperature
■ Cab/Sleeper Temperature
When these variables fall below
predetermined values, DDEC will
start the engine and allow it to idle
until the parameters are brought
to in-range values. Optimized Idle
provides benefits of:
■ Less Fuel Used
■ Extended Battery Life
■ Reduced Idle Time
■ Safety

Maintenance
Alert System
The Maintenance Alert System
(MAS) is designed to take the guess-
work out of filter and fluid checks
and changes. Sensors monitor oil
level, coolant level, and pressure
drop across the oil, fuel and air filters.
The MAS monitor is mounted in the
coach for easy access by service
technicians when the vehicle enters
the fuel and service island. When fil-
ters begin to clog or fluid levels drop,
DDEC illuminates a light indicating
what maintenance item needs to be
serviced. No hassle, no guesswork,
no wasted downtime.
“We had to switch to the Series 60 because
the residual value is higher.”
