low shock integration attack

series of low level shocks, due to a number of impacts on the supervised material integrating over a certain time, e.g impacts generated by chiselling on a concrete surface

3.1.11

standard immunity window

framed window, which is used for all immunity tests, where a framed window is required, according to A.1

3.2 Abbreviations

CIE Control & Indicating Equipment

4 Functional requirements

4.1 General

A shock detector consists of one or more shock sensor and an analyser, which may either be in the same housing, or in separate housings Furthermore the analyser can be integrated into another component of the Intruder & Hold Up alarm system (for example the CIE)

Trang 12

4.2 Event Processing

Shock detectors shall process the events in accordance with Table 1

Table 1 — Events to be processed by Grade

Key M = Mandatory, Op = Optional

a Mandatory for wire-free at grades 2, 3 and 4; mandatory for all surface mounted grade 3 and 4 types, optional for wired surface mounted grades 1 and 2 Not required for wired, sealed / potted and flush mounted types grade 3

b Mandatory for wire-free at all grades Only required if power is for normal local operation, e.g purely switch based solutions do not fall under this requirement; however if signal processing (except if it is the CIE itself) is required to process the output of the sensor, such an event shall be generated No generation of a message or signal is required when the condition is detected by the CIE due to system design, e.g bus based systems

c Only required if signal processing is used to generate any signal or message, e.g purely mechanical based solutions do not fall under this requirement No generation of

a message or signal is required when the condition is detected by the CIE due to system design, e.g bus based systems

Trang 13

Shock detectors shall generate signals or messages in accordance with Table 2

Table 2 — Generation of Signals or Messages

M = Mandatory

NP = Not Permitted

Op = Optional

* An independent signal or message may be provided instead

NOTE 1 This permits two methods of signalling a masking event: either by the

intrusion signal and fault signal, or by a dedicated masking signal or message Use of the

intrusion signal and fault signal is preferable, as this requires fewer connections between

CIE and shock detector If multiple events overlap there will be some signal combinations

that may be ambiguous To overcome this ambiguity it is suggested that shock detectors

should not signal ‘intrusion‘ and ‘fault‘ at the same time except to indicate masking This

implies that the shock detector should prioritise signals, e.g 1 Intrusion, 2 Fault, 3 Masking

** Alternatively Total loss of Power Supply shall be determined by loss of communication

with the shock detector

NOTE 2 When, in Table 1, an event may optionally generate signals or messages,

they shall be as shown in this table

NOTE 3 It is accepted that a bus system may send out dedicated signals or

messages and does not necessarily have to follow the mapping of Table 2, provided that all

of the required events are signalled

4.3 Detection

4.3.2 Indication of detection

Powered shock detectors at Grades 3 and 4 that include processing capabilities shall provide an indicator at the detector to indicate when an intrusion signal or message has been generated Self-powered shock detectors (e.g detectors which rely on the energy resulting from the impact or a series of impacts) do not require such an indicator

At Grades 3 and 4 this indicator shall be capable of being enabled and disabled remotely at Access Level 2

4.4 Immunity to false alarm sources

a Not required for wired, potted / sealed and flush mounted types grade 3

4.6.2 Resistance to and detection of unauthorised access to components and means of adjustment

All components, means of adjustment and access to mounting screws, which, when interfered with, could adversely affect the operation of the shock detector, shall be located within the shock detector housing Such access shall require the use of an appropriate tool and depending on the grade as specified in Table 3, shall generate a tamper signal or message before access can be gained

It shall not be possible to gain such access without generating a tamper signal or message or causing visible damage Sealed detectors do not require the means to detect access to the inside of the detector, as long as access to any adjustments is not possible or an attempt generates a tamper signal or message before access can be gained

4.6.3 Detection of removal from the mounting surface

A tamper signal or message shall be generated if the shock sensor is removed from its mounting surface, in accordance with Table 3
