The manufacturer shall specify the lowest and the highest detection level of the supported area of coverage on a specified material for an impact defined at a certain energy level according to Table G.1. Each of the specified lowest and highest detection levels will be tested.

This test will verify the detection performance for sensitivity and area of coverage according to the supported conditions claimed by the manufacturer for a low shock integration attack.

This test only applies, if the manufacturer claims his product supports this feature

There are minimum performance requirements for low shock integration attack detection which need to be fulfilled by the shock detector according to Table G.1.

Furthermore, the manufacturer can specify other performance requirements, which will be verified by testing against the performance specifications provided by the manufacturer.

The manufacturer shall specify the lowest and the highest detection level of the supported area of coverage on a specified material for an impact defined at a certain energy level as specified in Table G.1. Each of the specified lowest and highest detection levels will be tested.

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.

The detector shall have sufficient immunity to false alarm sources if the following requirements have been met:

No intrusion signal or message shall be generated as a result of the false alarm sources according to each individual test clause.

If not defined in the individual test section differently, for this clause the tests will be performed on the standard immunity test window as defined in 3.1.10, wherever a monitored object is required.

The detector shall not generate an intrusion signal or message when small objects such as hail, sand, gravel etc. hit the outside of the monitored surface, when set to the chosen sensitivity level required to pass the gross attack detection performance test. The tests are described in 6.7.2.

The detector shall not generate an intrusion signal or message when hard objects (e g. handlebars of a bicycle) hit the outside of the monitored surface, when set to the chosen sensitivity level required to pass the gross attack detection performance test. The tests are described in 6.7.3.

The detector shall not generate an intrusion signal or message when permanent pressure changes applied to the monitored surface, when set to the chosen sensitivity level required to pass the gross attack detection performance test. The tests are described in 6.7.4.

The detector shall not generate an intrusion signal or message when dynamic pressure changes (due to wind, etc.) applied to the monitored surface, when set to the chosen sensitivity level required to pass the gross attack detection performance test. The tests are described in 6.7.5.

The detector shall not generate an intrusion signal or message when for each standard installation material (glass plate, wooden plate & concrete plate as defined in Annex A), a minimum force will be issued at a given distance from the detector, when set to the chosen sensitivity level required to pass the gross attack detection performance test. The tests are described in 6.7.6.

Shock detectors using wired interconnections shall be able to provide an intrusion signal or message not more than 15 s after the end of the preceding intrusion signal or message.

Shock detectors using wire free interconnections shall be able to provide an intrusion signal or message after the end of the preceding intrusion signal or message within the following times:

The shock detector shall meet all functional requirements within 180 s of the power supply reaching its nominal voltage as specified by the manufacturer.

The shock detector shall automatically test itself at least once every 24 h according to the requirements of Tables 1 and 2. If normal operation of the shock detector is inhibited during a local self-test, the shock detector inhibition time shall be limited to a maximum of 30 s in any period of 2 h.

A shock detector shall process remote self tests and generate signals or messages in accordance with Tables 1 and 2 within 10 s of the remote self test signal being received, and shall return to normal operation within 30 s of the remote test signal being received

Tamper security requirements for each grade of shock detector and I or the individual components it consists of as shown in Table 3.

Table 3 -Tamper security requirements

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 or each individual component the shock detector consists of. 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 generates a tamper signal or message before access can be gained.

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

It shall not be possible to inhibit any signals or messages with a magnet of grade dependence according to Table 3.

Means shall be provided to detect inhibition of the operation of the shock sensor by masking according to the requirements of Table 3. For grade 3 products it is allowed that the detector is immune to a masking condition and operates within the normal boundaries as specified by the manufacturer.

There are different potential ways of masking a shock sensor. Therefore two different tests will be performed dependent on grade.

The first masking test will be to immobilise the active sensor component of a shock sensor with a magnetic field in a position, where it is no longer able to detect gross attacks and/or low shock integration attacks.

The second masking test will verify the ability of the shock sensor housing to detect the unauthorized access to prevent the fixing of the active sensor component of a shock sensor e.g. via a screw or superglue.

NOTE 1 In an l&HAS, any masked shock sensor should prevent setting of the system, as long as it is not immune to the masking condition.

The maximum response time for the masking detection device shall be 180 s. Masking shall be signalled according to the requirements of Table 2. The signals or messages shall remain for at least as long as the masking condition is present. A masking signal or message shall not be reset while the masking condition is still present. Alternatively the masking signal or message shall be generated again within 180 s of being reset if the masking condition is still present.

NOTE 2 From a system design point of view, it would be preferable for masked shock sensors and/or detectors to automatically reset after the masking condition is removed.

For shock detectors where detection of masking may be remotely disabled, the detection of masking shall operate when the l&HAS is unset; it is not required to operate when the l&HAS is set.

The grade dependencies appear in Table 4. These requirements do not apply to shock detectors having Type C power supplies. For these shock detectors refer to EN 50131-6.

Table 4 - Electrical requirements

The shock detectors or its individual components (sensor and/or analyser), when applicable, quiescent and maximum current consumption shall not exceed the figures claimed by the manufacturer at the nominal input voltage.

The shock detectors or its individual components (sensor and/or analyser), when applicable, shall meet all functional requirements when the input voltage lies between ± 25 % of the nominal value, or between the manufacturer’s stated values if greater. When the supply voltage is raised slowly, the shock detectors or its individual components (sensor and/or analyser), when applicable, shall function normally at the specified range limits.

The shock detectors or its individual components (sensor and/or analyser), when applicable, shall meet all functional requirements during the sinusoidal variation of the input voltage by ±10% of nominal, at a frequency of 100 Hz.

No signals or messages shall be caused by a step in the input voltage between nominal and maximum and between nominal and minimum.

Shock detectors or its individual components (sensor and/or analyser), when applicable, shall meet the requirements of the environmental tests described in Tables 5 and 6. These tests shall be performed in accordance with EN 50130-5 and EN 50130-4.

Unless specified otherwise for operational tests, the shock detectors or its individual components (sensor and/or analyser), when applicable, shall not generate unintentional intrusion, tamper, fault or other signals or messages when subjected to the specified range of environmental conditions.

Impact tests shall not be carried out on delicate shock detector components such as LEDs, optical windows or lenses.

For endurance tests, the shock detector or its individual components (sensor and/or analyser), when applicable, shall continue to meet the requirements of this specification after being subjected to the specified range of environmental conditions.

Manufacturer’s documented instructions regarding mounting and operation shall be read and applied to all tests.

The detectors sensor elements will be mounted according to the manufacturer’s description on the monitored object (e.g. glass window, concrete wall or door).

The tests will be performed with the types of materials claimed to be supported by the manufacturer, but at least with the materials defined in Annex A to perform the minimum detection performance tests.

The detector or its individual components (sensor and/or analyser), when applicable, shall be connected to the nominal supply voltage and connected to the monitoring system that is appropriate to the test. It shall be allowed to stabilise for 180 s. The intrusion signal or message output shall be monitored. If multiple sensitivity modes are available, any non-compliant modes shall be identified by the manufacturer. All compliant modes shall be tested. The detector shall be mounted according to the installation instructions, any cover(s) shall be mounted properly before any test takes place.

The purpose of the Basic Detection Test is to verify that a detector is still operational after a test or tests has/have been carried out. The Basic Detection Test verifies only the qualitative performance of the detector.

The detector shall generate an intrusion signal or message when the detector or its individual components (sensor/s), when applicable, are mounted according to the manufacturer instructions, set to maximum sensitivity level and tests are carried out according to 6.4.2.2.

The test will be performed according to the manufacturer’s instructions after the first installation, the settings and results will be noted to verify that all detectors or its individual components (sensor/s), when applicable, are installed correctly, it will be called the initial test. It will be performed again, after and/or during the environmental tests under the same conditions / settings of the initial test had been performed, to verify that the detectors will still function as claimed by the manufacturer (e.g. detection range). The result will then be compared to those of the initial test.

If the test is not compatible with the detector, use the manufacturer’s information to generate the correct algorithm.

Pass / fail criteria: The detector(s) shall produce an intrusion signal or message when exposed to an alarm stimulus both before and after being subjected to any test that may adversely affect its performance.

The general test conditions of 6.2.2 shall apply to all tests in this series.

Detection performance shall be tested against the manufacturer’s documented claims. Any variable controls shall be set to the values recommended by the manufacturer to achieve the claimed performance.

The detectors shall be assessed in the specified test environment.

All performance tests are based on physical shock characteristics (e.g. the shock in order to penetrate the monitored area) of the size and types of material claimed to be supported by the manufacturer including the standard material types listed in Annex A.

The minimum requirement for this test shall include at least the materials and minimum distances listed in Table G.1. If the manufacturer claims to support wider ranges and/or other materials, additional tests to the ones described in this section need to be performed for each claim.

Calibrated spring-operated hammer(s) according to Annex E will be used for testing the standard maximum sensitivity level according to the minimum settings per material as test tool in Annex G.

The values defined in Annex G are the minimum performance to be achieved by all shock detectors, if further settings are allowed to achieve higher sensitivity, these should be documented by the manufacturer and duly tested, when set to the chosen sensitivity level required to pass, the immunity tests shall be carried out successfully, when the detector is set for each higher sensitivity level.

The shock detector shall be set to the sensitivity level as defined by the manufacturer and appropriate for the monitored material and area. The level needs to be adjusted when the monitored material and area is changed. Furthermore the individual settings shall be noted, as those levels will be used for the immunity tests carried out later.
