NOTE

The

Protection Panel

continuously

monitors system integrity and displays the
information via the “SYSTEM OK” and fire
“TROUBLE” indicators.

Operational sequence (fire)

1. A fire detector or liner thermal detector

detects a fire in the engine compartment and
sends a signal to the

Protection Panel

in the

driver’s area.

2. The fire “ALARM” lamp on the

Protection

Panel

will illuminate solid red and an audible

alarm will sound.

3. The operator shall bring the vehicle to a safe

stop.

4. The system automatically shuts down the

vehicle engine and discharges the
extinguisher into the engine compartment 15
seconds after the fire alarm starts unless
advanced or delayed by the operator.

If the operator presses the

Manual

Activation Switch

, all delays will

terminate and the engine shutdown and
extinguisher discharge will occur
immediately.

If the operator presses and releases the

Delay Engine Stop

switch once, the

engine shutdown and extinguisher
discharge will be delayed by an additional
15 seconds.

WARNING

The engine will stop 15 seconds after the fire
alarm starts. The operator must be prepared
to bring the vehicle to a safe stop as soon as
the alarm sounds. Steering may become
difficult after engine shutdown. If more time is
required, the “DELAY ENGINE STOP” switch
may be pressed and released for an
additional 15 second delay.

WARNING

The extinguisher discharge may cause an
obscuring cloud behind and near the vehicle.

5. The red fire “ALARM” lamp and audible alarm

will stay on. The yellow fire “TROUBLE” lamp
will also be on indicating a discharged
extinguisher.

6. The system must be reset and the fire

extinguisher removed and replaced in
accordance with the System Reset portion of
the Kidde Dual Spectrum Operation &
Maintenance Manual.

TIRE PRESSURE MONITORING SYSTEM
(TPMS) (OPTIONAL)

The coach may be equipped with the optional
Tire Pressure Monitoring System (TPMS).

Description

System includes the following elements:

•

Special tire valves;

•

RF sensor inside each tire, fixed to the

valve;

•

3 antennas to receive the sensors RF signal

(one in the front spare tire compartment, one
above the L.H. side rear wheels and one
above the R.H. side rear wheels);

•

A TPMS receiver connected to the antennas

and located in the front electrical
compartment, above the CECM;

•

A TPMS display built in the L.H. dashboard

panel;

•

A “FLAT TIRE” telltale panel indicator.

The section of the special tire valves located
inside the tire is dome-shaped to allow fixing the
sensor.

Sensors provide continuous tire pressure and
temperature reading.

The normal sensor battery lifespan is 5 years.
The remaining lifespan is displayed as a
percentage in the TPMS display.

NOTE

It is recommended to check the remaining
battery lifespan when changing the tires in
order to replace the sensors at the same time
if they are due for replacement before the next
change.

The screw fixing the sensor to the valve can only
be used once because the threads are powder-
coated to lock the sensor in place and prevent
unfastening.
