Part II – Approval of a vehicle with regard to its alarm system

When a VAS approved to Part I of this Regulation or UN Regulation No 116 Supplement 7 to the original version, or UN Regulation No 97 Supplement 8 to the 01 series of amendments is installed in a vehicle submitted for approval to Part II of this Regulation, tests required to be passed by a VAS in order to obtain approval to Part I of this Regulation shall not be repeated.

9. Definitions

For the purpose of Part II of this Regulation,

9.1. ' Alarm system(s) ' (AS) means an arrangement of components fitted as original equipment in a vehicle type, designed to indicate intrusion into or interference with the vehicle; these systems may provide additional protection against unauthorized use of the vehicle.

9.2. ' Vehicle type with regard to its alarm system ' means vehicles which do not differ significantly in such essential aspects as: (a) The manufacturer's trade name or mark; (b) Vehicle features which significantly influence the performances of the AS; (c) The type and design of the AS or VAS.

9.3. ' Approval of a vehicle ' means the approval of a vehicle type with regard to the requirements laid down in paragraphs 10, 11 and 12 below.

9.4. Other definitions applicable to Part II are contained in paragraph 2 of this Regulation.

10. General specifications

10.1. ASs shall be designed and built in such a way that they, in the event of intrusion into or interference with a vehicle, provide a warning signal, and may include an immobilizer. 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.

10.2. Vehicle which are equipped with alarm systems shall comply with the relevant technical requirements, especially with regard to electromagnetic compatibility (EMC).

10.3. The AS and components thereof shall not activate inadvertently, particularly whilst the engine is in its running mode.

10.4. Failure of the AS, or failure of its electrical supply shall not affect the safe operation of the vehicle.

10.5. The alarm system, its components and the parts controlled by them shall be so installed as to minimize 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.

10.6. 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.

11. Particular specifications

11.1. Protection range

11.1.1. Specific requirements

The AS 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.

The installation of additional efficient sensors for information/display, e.g.:

(a) Of intrusion into the vehicle, e.g. passenger compartment control, window glass control breakage of any glazed area; or

(b) Of attempted vehicle theft, e.g. inclination sensor;

are allowed, taking account of measures to prevent any unnecessary sounding of the alarm (= false alarm, see paragraph 11.1.2 below).

Insofar as these additional sensors generate an alarm signal even after an intrusion has occurred (e.g. by breakage of a glazed area) or under external influences (e.g. wind), the alarm signal, activated by one of the above-mentioned sensors, shall be activated not more than 10 times within the same activation period of the AS.

In this case the activation period shall be limited by the authorized unsetting of the system as a result of the vehicle user's action.

Some kinds of additional sensors, e.g. passenger compartment control (ultrasonic, infrared) or inclination sensor, etc., may be intentionally deactivated. In this case, separate deliberate action shall be taken each time before the AS is set. It shall not be possible to deactivate the sensors while the alarm system is in a set state.

11.1.2. Safety against false alarm

11.1.2.1. It shall be ensured that the AS both in set and unset conditions, cannot cause the alarm signal to sound unnecessarily, in the event of: (a) An impact on the vehicle: test specified in paragraph 7.2.13; (b) Electromagnetic compatibility: tests specified in paragraph 7.2.12; (c) Reduction of battery voltage by continuous discharge: test specified in paragraph 7.2.14; (d) False alarm of the passenger compartment control: test specified in paragraph 7.2.15.

11.1.2.2. If the applicant for approval can demonstrate, e.g. by technical data, that safety against false alarm is satisfactorily ensured, the technical service responsible for conducting approval tests may not require some of the above tests.

11.2. Audible alarm

11.2.1. General

The warning signal shall be clearly audible and recognizable and shall differ significantly from the other audible signals used in road traffic.

In addition to the original equipment audible warning device, a separate audible warning device may be fitted in the area of the vehicle which is controlled by the AS, where it shall be protected against easy, rapid access by persons.

If a separate audible warning device according to paragraph 11.2.3.1 below is used, the original equipment standard audible warning device may additionally be actuated by the AS, provided that any tampering with the standard audible warning device (generally more accessible) does not affect the operation of the additional audible warning device.

11.2.2. Duration of the audible signal

Minimum: 25 s

Maximum: 30 s

The audible signal may sound again only after the next interference with the vehicle, i.e. after the above-mentioned time span. (Restrictions: see paragraphs 11.1.1 and 11.1.2 above).

Unsetting of the alarm system shall immediately cut the signal.

11.2.3. Specifications concerning the audible signal

11.2.3.1. Constant tone signal device (constant frequency spectrum), e.g. horns: acoustical, etc., data according to UN Regulation No 28, Part I. Intermittent signal (on/off): Trigger frequency: (2 ± 1) Hz On time = off time ± 10 per cent

11.2.3.2. Audible signal device with frequency modulation: acoustical, etc., data according to UN Regulation No 28, Part I but equal passage of a significant frequency range within the above-mentioned range (1 800 through 3 550 Hz) in both directions. Passage frequency: (2 ± 1) Hz

11.2.3.3. Sound level The sound source shall be: (a) Either an audible warning device approved under UN Regulation No 28, Part I; (b) Or a device meeting the requirements of UN Regulation No 28, Part I, paragraph 6.1 and 6.2. However, in the case of a different sound source from the original equipment audible warning device, the minimum sound level may be reduced to 100 dB(A), measured under the conditions of UN Regulation No 28, Part I.

11.3. Optical alarm - if fitted

11.3.1. General
