9. Operational reliability

Means shall be provided to ensure that operator errors which might adversely influence the normal operation of an l&HAS are either prevented or indicated.

Components of an l&HAS used during the operation of an l&HAS shall be clearly and unambiguously marked and logically arranged in such a manner as to minimise the possibility of incorrect operation. Only those functions accessible at the users access level shall be made available to the user.

9. Functional reliability

l&HAS components shall comply with relevant standards. The design and the configuration of an l&HAS shall ensure the operation of the l&HAS according to the requirements of this standard. This shall be achieved by

• clear rules for design and installation,

• clear rules for adjustment and maintenance,

• correct manufacture,

• regular maintenance,

• designed to provide a high signal-to-noise ratio,

• well designed software,

• elements operating within design limits (voltage, temperature),

• testability of functions (by user, installer),

• function monitoring, e g. a watchdog circuit.

12. Environmental requirements

The environmental stability of l&HAS shall be of the same level in all grades. The operation of an l&HAS shall not be influenced when the l&HAS is subject to the environmental conditions specified in Clause 7 and when exposed to EMC conditions specified in 12.1. An l&HAS shall neither change state, suffer damage to components or substantially change in performance. EN 50130-5 describes environmental test methods which shall be applied to l&HAS components.

The electromagnetic compatibility performance requirements for l&HAS components are described in EN 61000-6-3 and EN 50130-4.

12. Electrical safety

An l&HAS component shall provide protection against electrical shock and consequential hazards by achieving compliance with the requirements of EN 60950-1 or EN 60065.

12. Documentation

    1. Intruder and hold-up alarm system documentation

Documentation relating to an l&HAS shall be concise, complete and unambiguous. Information shall be provided sufficient to install, put into operation, operate and maintain an l&HAS.

Instructions relating to the operation of an l&HAS shall be designed to minimise the possibility of incorrect operation and be structured to reflect the access level of the user.

Documentation relating to l&HAS components shall be concise, complete and unambiguous. The documentation shall be sufficient to ensure the correct installation, putting into operation and maintenance of l&HAS components. Sufficient information shall be provided to ensure the integration of each component with other l&HAS components.

Component documentation shall include the following:

• name of manufacturer or supplier;

• description of equipment;

• standard to which component claims compliance;

• name ^2> or mark of the certification body;

• security grade;

• environmental class.

12. Marking/ldentification

All l&HAS components shall be marked with the following:

• name of manufacturer or supplier;

• type;

• date of manufacture or batch number or serial number;

• security grade;

• environmental class.

The marking shall be legible, durable and unambiguous. When space for marking of an l&HAS component is limited, codes may be used providing these are described in the associated component documentation. When insufficient space is available for codes the component shall include means of identification which allows cross reference to documentation providing the required information.

(informative)

Alarm transmission system performance criteria

The security classification of an alarm transmission system is defined as the combination of 5 parameters:

D transmission time - classification

T reporting time

M transmission time - maximum values

S substitution security

I information security

The value of these parameters are defined in EN 50136-1-1 and the following tables and in the text "Signalling security".

Table B.1 - Transmission time classification

Table B.2 - Transmission time - Maximum values

Table B.3 - Reporting time classification

Signalling security

The alarm transmission system shall provide measures to prevent or detect deliberate attempts to interfere with the transmission of an alarm message or other information transmitted between an l&HAS and it’s associated alarm receiving centre by blocking or substitution in one of the following ways.

Substitution security: Protection against unauthorised substitution of the alarm system transceiver with similar equipment along the Alarm transmission system transmission path shall be provided in one of the following ways:

SO No measures.

51. Measures to detect substitution of the supervised premises transceiver by addition of an identity or address in all messages transmitted on the alarm transmission path.

52. Measures to detect substitution of the supervised premises transceiver by

1. encryption of an identity or address in all messages transmitted on the alarm transmission path,

2. authentication of the supervised premises transceiver by the addition of a different and un­revealed code for each connected transceiver, or

3. another measure as specified by the manufacturer.

Authentication always requires a sufficient number of keys to provide each connected transceiver with a unique code. The identity range in S2 must not be less than 250 unique addresses.

Information security: Protection of the information transmitted by the alarm transmission system shall be provided in one of the following ways:

IO No measures.

11. Measures to prevent unauthorised reading of the information transmitted.

NOTE This may be accomplished by encryption.

11. Measures to prevent unauthorised modification of the information transmitted.

NOTE This may be accomplished by encryption or by a cryptographic authentication method.

11. Measures to prevent unauthorised reading and modification of the information transmitted.

Encryption algorithms shall be such that for synchronous alarm transmission systems the data pattern of any successive 100 bits shall not be repeated within 10 000 000 successive bits, or for asynchronous systems the data pattern of any successive 100 bytes shall not be repeated within 1 000 000 successive bytes.E
