of conformity shall provide a list of such reference marks.
 A model of the certificate of conformity is given in Annex 6 to this Regulation.
5. GENERAL SPECIFICATIONS
5.1. VAS shall, in the event of intrusion into or interference with a vehicle, provide a warning signal.
 The warning signal shall be audible and in addition may include optical warning devices, or be a radio alarm or any combination of the above.
5.2. VASs shall be designed, constructed and installed in such a way that the vehicle when equipped shall continue to comply with the relevant technical requirements, especially with regard to electromagnetic compatibility (EMC).
5.3. If the VAS includes the possibility of a radio transmission, e.g. for setting or unsetting of the alarm or for alarm transmission, it shall comply with the relevant ETSI Standards. [4]/ The frequency must be 433.92 MHz and the maximum radiated power 25 mW.
5.4. The installation of a VAS in a vehicle shall not be capable of influencing the vehicle's performance (in the unset state), or its safe operation.
5.5. The VAS and components thereof shall not activate inadvertently, particularly whilst the engine is in its running mode.
5.6. Failure of the VAS, or failure of its electrical supply shall not affect the safe operation of the vehicle.
5.7. The VAS, its components and the parts controlled by them shall be designed, built and installed in such a way as to minimise the risk for anyone to make them inoperable or to destroy them rapidly and without calling attention, e.g. using low-cost,
 easily-concealed tools, equipment or fabrications readily available to the public at large.
5.8. The means of setting and unsetting of the VAS shall be designed in such a way that it does not invalidate the requirements of Regulation No. 18.  Electrical connections to components covered by this Regulation are allowed.
5.9. The system shall be so arranged that the shorting out of any warning signal circuit shall not render inoperative any aspects of the alarm system, other than the circuit which is shorted out.
5.10. VAS may include an immobiliser which shall comply with the requirements of Part III of this Regulation.
6. PARTICULAR SPECIFICATIONS
6.1. Protection range
6.1.1. Specific requirements
 The VAS shall at least detect and signal the opening of any vehicle door, engine bonnet and luggage compartment.  The failure or switching off of light sources, e.g. passenger compartment light, shall not impair the control operation.
 Additional efficient sensors for information/display, e.g. :
 of intrusions into the vehicle, e.g. passenger compartment control, window glass control, breakage of any glazed area, or
 of attempted vehicle theft, e.g. inclination sensor
 are allowed, taking account of measures to prevent any unnecessary sounding of
