"
Model D
The above approval mark affixed to a fire suppression system shows that the fire suppression system
type has been approved in the Netherlands (E 4) as a component, pursuant to Regulation No. 107 under
approval number 062439. The approval number indicates that the approval was granted according to the
requirements of Regulation No. 107 as amended by the 06 series of amendments."

system providing the driver with both an acoustic and a visual signal, and activating the
hazard warning signal, in the event of excess temperature in the engine compartment and in
each compartment where a combustion heater is located.
In addition to the alarm system, vehicles of Class III shall be equipped with a fire
suppression system in the engine compartment and each compartment where a combustion
heater is located. Vehicles of Classes I, II, A and B, may be equipped with a fire
suppression system in the engine compartment and in each compartment where a
combustion heater is located.
7.5.1.5.1. The alarm system and the fire suppression system, if fitted, shall be automatically activated
through a fire detection system. The detection system shall be designed so as to detect a
temperature in the engine compartment, and in each compartment where a combustion
heater is located in excess of the temperature occurring during normal operation."
