all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.

INTRODUCTION
This part 2-6 of the IEC 62642 series of standards gives requirements for intrusion detectors
with opening contacts (magnetic) used in intrusion and hold-up alarm systems. The other
parts of this series of standards are as follows:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors
Part 2-3 Intrusion detectors – Microwave detectors
Part 2-4 Intrusion detectors – Combined passive infrared / Microwave detectors
Part 2-5 Intrusion detectors – Combined passive infrared / Ultrasonic detectors
Part 2-6 Intrusion detectors – Opening contacts (magnetic)
Part 2-71 Intrusion detectors – Glass break detectors – Acoustic
Part 2-72 Intrusion detectors – Glass break detectors – Passive
Part 2-73 Intrusion detectors – Glass break detectors – Active
Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Requirements for interconnections equipment using radio frequency techniques
Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices/systems
This International Standard is for opening contacts (magnetic) used as part of intrusion and
hold-up alarm systems (I&HAS) installed in buildings. It includes four security grades and four
environmental classes.
The purpose of an opening contact (magnetic) is to detect a displacement of a door or window
from the defined closed position. The opening contact comprises two separate parts, the
active connection between which is at least one magnetic field. Separating the two parts
disturbs the connection and produces an intruder signal or message.
The number and scope of these signals or messages will be more comprehensive for systems
that are specified at the higher grades.
This International Standard is only concerned with the requirements and tests for opening
contacts (magnetic). Other types of detectors are covered by other documents identified
IEC 62642-2 series.

1 Scope
This part of the IEC 62642 provides for security grades 1 to 4, (see IEC 62642-1) specific or
non-specific wired or wirefree opening contacts (magnetic), and includes the requirements for
four environmental classes covering applications in internal and outdoor locations as specified
in IEC 62599-1.
A detector fulfils all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this International Standard may
be included in the detector, providing they do not influence the correct operation of the
mandatory functions.
The two separate parts of the opening contact (magnetic) are referred to in the body of this
International Standard as the detector.

4.4.2 Switch on delay
Where a detector requires an internal or external power supply in accordance with 4.6, the
detector shall meet all functional requirements within 180 s of the power supply reaching its
nominal voltage.
4.4.3 Fault condition signals
A detector shall generate a fault signal or message in accordance with the manufacturer’s
specification and the provisions of Table 2 in the presence of a fault condition, according to
Table 1, or as a result of an internal self-test if this feature is provided.
4.5 Tamper security
4.5.1 Tamper security requirements
All terminals and means of mechanical and electronic adjustments shall be located within the
detector’s housings.
The tamper security requirements for each grade of detector are shown in Table 1.
4.5.2 Prevention of unauthorised access to the inside of the detector through covers
and existing holes
Access holes shall not allow interference with the operation of the detector by probing with
commonly available tools. Damage shall not be caused that would prevent normal operation.
If the detector can be opened, a tool shall be required to open the unit. For grades 2, 3 and 4
detectors, all covers giving access to components that could adversely affect the operation of
the detector shall be fitted with a tamper detection device that shall generate signals or
messages in accordance with Table 2. It shall not be possible to gain such access without

62642-2-6 Ó IEC:2010 – 13 –
generating a tamper signal or message or causing visible damage. Sealed contacts do not
require the means to detect access to the inside of the detector.
4.5.3 Detection of removal from the mounting surface
A detection device shall be fitted that generates a tamper signal or message in accordance
with Table 2 if the detector is removed from the mounting surface. Operation of the tamper
device shall not be compromised by external means. This device shall activate before access
can be gained to it.
4.5.4 Magnetic field interference
When the detector is mounted in accordance with the manufacturer’s instructions and is
subject to the presence of an external magnetic field generated by the interference test
magnets specified in Annex A and applied to the faces of the detector according to Annex F,
the detector shall either:
be immune to any influence by the interference test magnets and continue to operate normally
with the make and break distances not exceeding twice those specified in accordance with
4.3.1,
or
generate an intrusion, and/or tamper, and/or fault, and/or other independent signal or
message in accordance with Table 2 when the make or break distances exceed twice those
specified in accordance with 4.3.1. These signals or messages may be generated either on
application of the interference test magnet or when the corresponding magnet has returned to
its original installed position.
NOTE The signals or messages generated by a grade 4 detector are intended to be used by the I&HAS to
positively identify an attempt to sabotage the detector through magnetic interference.
4.5.5 Matched coded pairs
A grade 4 detector shall consist of a matched pair of switch component and corresponding
magnet. The means of matching shall have a minimum of 8 differs. It shall not be possible to
determine the specific pair identity by visual inspection of the detector.
The probability of the use of each code shall be equal.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

INTRODUCTION
This part 2-6 of the IEC 62642 series of standards gives requirements for intrusion detectors
with opening contacts (magnetic) used in intrusion and hold-up alarm systems. The other
parts of this series of standards are as follows:
Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors
Part 2-3 Intrusion detectors – Microwave detectors
Part 2-4 Intrusion detectors – Combined passive infrared / Microwave detectors
Part 2-5 Intrusion detectors – Combined passive infrared / Ultrasonic detectors
Part 2-6 Intrusion detectors – Opening contacts (magnetic)
Part 2-71 Intrusion detectors – Glass break detectors – Acoustic
Part 2-72 Intrusion detectors – Glass break detectors – Passive
Part 2-73 Intrusion detectors – Glass break detectors – Active
Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Requirements for interconnections equipment using radio frequency techniques
Part 6 Power supplies
Part 7 Application guidelines
Part 8 Security fog devices/systems
This International Standard is for opening contacts (magnetic) used as part of intrusion and
hold-up alarm systems (I&HAS) installed in buildings. It includes four security grades and four
environmental classes.
The purpose of an opening contact (magnetic) is to detect a displacement of a door or window
from the defined closed position. The opening contact comprises two separate parts, the
active connection between which is at least one magnetic field. Separating the two parts
disturbs the connection and produces an intruder signal or message.
The number and scope of these signals or messages will be more comprehensive for systems
that are specified at the higher grades.
This International Standard is only concerned with the requirements and tests for opening
contacts (magnetic). Other types of detectors are covered by other documents identified
IEC 62642-2 series.

Part 2-6: Intrusion detectors –
Opening contacts (magnetic)
1 Scope
This part of the IEC 62642 provides for security grades 1 to 4, (see IEC 62642-1) specific or
non-specific wired or wirefree opening contacts (magnetic), and includes the requirements for
four environmental classes covering applications in internal and outdoor locations as specified
in IEC 62599-1.
A detector fulfils all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this International Standard may
be included in the detector, providing they do not influence the correct operation of the
mandatory functions.
The two separate parts of the opening contact (magnetic) are referred to in the body of this
International Standard as the detector.
This International Standard does not apply to system interconnections.

detector’s housings.
The tamper security requirements for each grade of detector are shown in Table 1.
4.5.2 Prevention of unauthorised access to the inside of the detector through covers
and existing holes
Access holes shall not allow interference with the operation of the detector by probing with
commonly available tools. Damage shall not be caused that would prevent normal operation.
If the detector can be opened, a tool shall be required to open the unit. For grades 2, 3 and 4
detectors, all covers giving access to components that could adversely affect the operation of
the detector shall be fitted with a tamper detection device that shall generate signals or
messages in accordance with Table 2. It shall not be possible to gain such access without

62642-2-6 Ó IEC:2010 – 13 –
generating a tamper signal or message or causing visible damage. Sealed contacts do not
require the means to detect access to the inside of the detector.
4.5.3 Detection of removal from the mounting surface
A detection device shall be fitted that generates a tamper signal or message in accordance
with Table 2 if the detector is removed from the mounting surface. Operation of the tamper
device shall not be compromised by external means. This device shall activate before access
can be gained to it.
4.5.4 Magnetic field interference
When the detector is mounted in accordance with the manufacturer’s instructions and is
subject to the presence of an external magnetic field generated by the interference test
magnets specified in Annex A and applied to the faces of the detector according to Annex F,
the detector shall either:
be immune to any influence by the interference test magnets and continue to operate normally
with the make and break distances not exceeding twice those specified in accordance with
4.3.1,
or
generate an intrusion, and/or tamper, and/or fault, and/or other independent signal or
message in accordance with Table 2 when the make or break distances exceed twice those
specified in accordance with 4.3.1. These signals or messages may be generated either on
application of the interference test magnet or when the corresponding magnet has returned to
its original installed position.
NOTE The signals or messages generated by a grade 4 detector are intended to be used by the I&HAS to
positively identify an attempt to sabotage the detector through magnetic interference.
4.5.5 Matched coded pairs
A grade 4 detector shall consist of a matched pair of switch component and corresponding
magnet. The means of matching shall have a minimum of 8 differs. It shall not be possible to

maximum and between nominal and minimum.
4.6.6 Total loss of external power
This subclause applies to detectors that require an external power supply.
This does not include any applied voltage to a purely reed based switch detector.
An intrusion signal or message shall be generated by the total loss of the supply voltage.
No generation of a message or signal is required when this total loss of external power
condition is detected by the CIE due to system design, e.g. bus based systems.
4.6.7 Low supply voltage
This subclause applies to detectors that require an external power supply.
NOTE This does not include any applied voltage to a purely reed based switch detector.
A fault signal or message shall be generated when the minimum level of voltage that is
required for the detector to operate reliably is compromised according to the specification of
the manufacturer. No generation of a message or signal is required when this low power
condition is detected by the CIE due to system design, e.g. bus based systems.
4.6.8 Interconnection Integrity
The detector shall provide a means to enable the I&HAS to monitor the integrity of the
interconnection. Where the interconnecting cable or wire is provided with the detector, means
shall be provided to permit the monitoring of this interconnecting cable in accordance with
IEC 62642-1 (e.g. a tamper loop or end of line resistor built into the body of the detector).
NOTE This requirement may be fulfilled either by the detector itself or by suitable system design.

Monitor the output of the detector with its corresponding magnet within the make distance.
Move the corresponding magnet to a position beyond the break distance. Record the status of
the intrusion signal or message during the test.
Pass/Fail criteria: An intrusion signal or message shall be generated when the magnet is
moved beyond the break distance.
6.4 Verification of detection performance
6.4.1 General
The general test conditions of 6.2 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.
6.4.2 Measurement of approach/removal distances
By moving the corresponding magnet relative to the switch component, measure the approach
and removal distances where the switch component generates intruder and reverse signals or
messages. Record the response of the switch component. Note the approach and removal
distances for all the configurations claimed in the manufacturer’s documentation.
Pass/Fail criteria: An intrusion signal or message shall be generated beyond the removal
distance and shall generate a reverse signal within the approach distance claimed in the
manufacturer’s documentation.
6.5 Switch-on delay, time interval between signals, and indication of detection
The general test conditions of 6.2 apply.
Switch on the detector’s power supply with the indicator enabled (if provided), and allow 180 s
for stabilisation. Carry out the BTD. Note the response. Carry out the BTD again, after the
grade-dependant time interval between signals according to 4.4.1. Note the response again.
Disable the intrusion indicator (if provided). Repeat the BTD.

62642-2-6 Ó IEC:2010 – 17 –
Pass/Fail criteria: The detector shall generate an intrusion signal or message in response to
the BTD. The intrusion signal or message and the intrusion indicator shall respond at the
same time. A second intrusion signal or message shall be generated after the grade-
dependant time interval specified in 4.4.1 has elapsed. With the indicator disabled (if
provided) the detector shall still generate an intrusion signal or message.
6.6 Tamper security
6.6.1 General
The general test conditions of 6.2 apply.
The tests of this subclause shall be applied to the detector at the grade in accordance with
Table 1.
6.6.2 Prevention of unauthorised access to the connections or components within the
detector
Attempt to overcome the tamper detection device by deliberate attack with normally available
objects as listed in Annex C, by distorting the housing or by attempting to access the
connections or components within the detector without causing visible external damage.
Grade dependency appears in Table 1. Monitor the outputs of the detector.
Pass/Fail criteria: Where there is no physical damage to the detector, a tamper signal or
message shall be generated before access is gained to any circuit connection or control that
can adjust the performance of the detector
6.6.3 Detection of removal from the mounting surface
The object of this test is to confirm the operation of the tamper device by removing the
detector from the mounting surface.
Place the unit on the mounting surface without the fixing screws, unless they form a part of
the tamper detection device.
Slowly prise the detector away from the mounting surface and attempt to prevent the tamper
device from operating by inserting a strip of steel between 100 mm and 200 mm long by
10 mm to 20 mm wide, and 1 mm thick between the rear of the detector and its mounting
surface. Attempt to gain access to the circuit connections or controls. Monitor the outputs of
the detector.
Pass/Fail criteria: A tamper signal or message shall be generated before the tamper device
can be inhibited or access is gained to any circuit connection or control that can adjust
performance.
6.6.4 Resistance to magnetic field interference
This test shall be performed for grade 3 and grade 4 products only.
The switch component and the corresponding magnet shall be installed according to the
manufacturer’s description with a separation distance calculated as 50 % of the specified
make distance on the y-axis. If a prohibited area is described by the manufacturer, the
distance of this area will be added to the previously calculated separation distance.
The test environment/installation shall support reproducible adding and removal of the
corresponding magnet without any changes to the original installation distance, to simulate
the opening and closing of the monitored object. The interference test magnets shall be
applied onto all exposed and accessible housing surfaces when mounted normally.

– 18 – 62642-2-6 Ó IEC:2010
For detector’s designed for use in both surface and flush mounted installations, then all
corresponding tests shall be performed.
For detector’s designed for installation in a ferromagnetic environment, the tests shall be
performed in such an environment following the installation instructions and using the
installation material (if required) by the manufacturer. For surface mount opening contacts,
the test shall be undertaken with the switch component placed on a steel mounting plate
based on the material defined in Annex E, having dimensions of
(600 mm ´ 600 mm ´ 1,6 mm). For flush mount opening contacts, the test shall be undertaken
using 2 steel mounting plates based on the material defined in Annex E, having dimensions of
(200 mm ´ 200 mm ´ 1,6 mm).
Surface mount opening contacts:
The interference test magnets shall be applied in both polarization directions at 2 points
randomly chosen on each surface both parallel and perpendicular to the surface, refer
