INTRODUCTION
This standard is part of the IEC 60839 series, written to include the following parts:
Part 11-1: Electronic access control systems – System and components requirements
Part 11-2: Electronic access control systems – Application guidelines
This part of IEC 60839 describes the general requirements for planning, installation, operation,
maintenance and documentation for the application of electronic access control systems
(EACS).
The performance of the EACS is determined by the security grades allocated to the access
points. A risk assessment that identifies the risks and perceived threats should first be carried
out in order to establish the appropriate security grades.
Four security grades are available based upon the knowledge and tools available to a person
intent upon gaining unauthorised access and the type of application, taking into account
specific organizational aspects and the value of the assets.
Separate guidance is provided for each activity along with recommendations for the
documentation needed. A brief description of each section covering the activities is provided
below:
System planning: this section is intended to assist the designer with the selection of an
electronic access control system (EACS) that provides the control of access and security
integrity commensurate with the value of the assets requiring protection and the associated
risks. See Clause 7.
System design should minimise potential vulnerabilities that could be exploited to circumvent
the access control measures. It is recommended that safeguards are incorporated to give
early warning of attempts to circumvent the access control measures. See 7.3.
System installation: this section is intended to help those responsible for installing the EACS
by identifying issues which should be considered prior to commencing the installation and
during the installation of the system in order to ensure the EACS is correctly implemented as
specified during system planning. See Clause 8.
Commissioning and system handover: this section provides guidance to ensure the level of
performance required in the system planning is obtained and that the end user is provided
with the necessary documentation, records and operating instructions during the handover of
the EACS. See Clause 9.
System operation and maintenance: includes information regarding the responsibilities of the
end user of the EACS to ensure the system is operated correctly and adequately maintained.
It covers inspection, service and the use of remote diagnostics in order that the level of
performance determined during the system planning stages can be maintained. See Clause
10.
ALARM AND ELECTRONIC SECURITY SYSTEMS –

Part 11-2: Electronic access control systems –
Application guidelines
1 Scope
This part of IEC 60839 defines the minimum requirements and guidance for the installation
and operation of electronic access control systems (EACS) and/or accessory equipment to
meet different levels of protection.
This standard includes requirements for planning, installation, commissioning, maintenance
and documentation for the application of EACS installed in and around buildings and areas.
The equipment functions are defined in the IEC 60839-11-1.
When the EACS includes functions relating to hold-up or the detection of intruders, the
requirements in standards relating to intrusion and hold-up are also applicable.
This standard provides application guidelines intended to assist those responsible for
establishing an EACS to ascertain the appropriate design and planning of the EACS, both in
terms of levels of protection and levels of performance necessary to provide the degree of
access control and protection considered appropriate for each installation. This is achieved by
scaling or classifying the features of electronic access control systems related to the security
functionality (e.g. recognition, access point actuation, access point monitoring, duress
signaling and system self-protection) in line with the known or perceived threat conditions.
This standard does not cover the methods and procedures for conducting a risk assessment.

6 Environmental and EMC considerations
6.1 General
Each component of an EACS is expected to operate correctly in its service environment and
that it will continue to do so for a reasonable time. Components shall be suitable for one of
the following environmental classes.
6.2 Environmental Class I – Equipment situated in indoor but restricted to
residential/office environment
Environmental Class I comprises environmental influences normally experienced indoors
when the temperature is well maintained (e.g. in a residential or commercial property).
NOTE Temperatures can be expected to vary between +5 °C and +40 °C.
6.3 Environmental Class II – Equipment situated indoor in general
Environmental Class II comprises environmental influences normally experienced indoors
when the temperature is not well maintained (e.g. in corridors, halls or staircases and where
condensation can occur on windows and in unheated storage areas or warehouses where
heating is intermittent).
NOTE Temperatures can be expected to vary between –10 °C and +55 °C.

– 10 – IEC 60839-11-2:2014 © IEC 2014
6.4 Environmental Class III – Equipment situated outdoor – Sheltered or indoor
extreme conditions
Environmental Class III comprises environmental influences normally experienced out of
doors when the EACS components are not fully exposed to the weather or indoors where
environmental conditions are extreme.
NOTE Temperatures can be expected to vary between –25 °C and +55 °C.
6.5 Environmental Class IV – Equipment situated outdoor – General
Environmental Class IV comprises environmental influences normally experienced out of
doors when the EACS components are fully exposed to the weather.
NOTE Temperatures can be expected to vary between –25 °C and +70 °C depending on the region. The
temperature range can be extended to plus and/or minus for different geographical or climatic zones.
6.6 EMC
It is recommended that installation good practice be followed to reduce the unwanted effects
of electrical interference, e.g. interconnection wiring should not be run in the same conduit or
trunking as cables carrying mains supplies, or network and data cables carrying high
frequency signals unless they are physically separated and/or suitably screened so as to
prevent cross interference.
Additional filtering and/or screening of interconnecting cables might be necessary for
applications known to have high levels of conducted or radiated electrical interference, e.g. an
industrial plant operating high power electrical equipment.
The manufacturers’ guidelines for electromagnetic compatibility should be followed.
7 System planning
7.1 General
The objectives of the system planning stage are to determine the extent of EACS, to select
components of the appropriate functionality/performance criteria, security grade and
environmental classification and to prepare a system design proposal.
An access control system comprises all the logical functionality, constructional and
organizational facilities together with the physical equipment required for controlling access.
Particular care should be taken to minimize inconvenience to authorized users.
The implementation of an access control system should be in accordance with the following
sequence:
a) risk assessment and security grading;
b) system and components selection;
c) operational considerations;
d) system installation;
e) system handover;
f) system operation and maintenance.
System installation shall be conducted in accordance with national and local regulations.

7.2 Risk assessment and security grading
It is essential that a risk assessment is performed before the implementation of the access
control system. The risk assessment chart of Figure 2 identifies the key considerations.

IEC
Figure 2 – Risk assessment chart
The security grade levels are defined in terms of the value of the assets requiring protection
and the determination (knowledge/skills) and methods of attack of persons intending to
bypass the system (adversaries). Refer to Table 1 for examples of typical applications for
each grade.
– Grade 1: Low risk. The adversary is expected to have little knowledge of the access
control system and be restricted to a limited range of easily available tools. Physical
security is provided to deter and delay adversaries. Assets have limited value and
adversaries will probably give up the idea of attacking when confronted with minimum
resistance.
– Grade 2: Low to medium risk. The adversary is expected to have limited knowledge of the
access control system and the use of a general range of tools and portable instruments.
Physical security is provided to deter, delay and detect adversaries. The assets have
higher value and adversaries are likely to give up the idea of succeeding when they realize
they may be detected.
– Grade 3: Medium to high risk. The adversary is expected to be conversant with the access
control system and have a comprehensive range of tools and portable electronic
equipment. Physical security is provided to deter, delay, detect and means are provided to
help identify adversaries. The assets have high value and adversaries may give up the
idea of succeeding when they realize they may be identified and caught.
– Grade 4: High risk. The adversary is expected to have the ability or resources to plan the
attack in detail and have a full range of equipment including means of substitution of
components in the access control systems. Physical security is provided to deter, delay,
detect and means are provided to help identify adversaries. The assets have very high
value and adversaries may give up the idea of succeeding when they realize they will be
identified and caught.

7.3 System design
7.3.1 System and components selection
The security grading shall be defined for each access point taking in consideration the needs
for control of entry and exit.
Different security grades can be used for access points in the same system. It shall be
ensured that the common system components, protecting access points with different security
grading, meet the requirements of the highest security grade access point that they are
operating in conjunction with (see Figure 3).

Figure 3 – Example of system grade selection
Where it is not practical to have different grades of access points managed by a single access
control system it is permitted to have more than one separate access control system. An
access point shall not be controlled by more than one separate access control system.
The mandatory functions of the equipment associated with each security grade are defined in
the IEC 60839-11-1.
Not all mandatory functions defined in the IEC 60839-11-1 need to be implemented in an
installed EACS. A list of allowed exceptions is provided in Annex A. Exceptions shall be
agreed between the installer and the system owner and be recorded in the as-built
documentation.
The installer shall point out to the system owner that exceptions from the requirements,
especially for access points, recognition and communication, may affect the functions and the
security of the whole EACS.

7.3.2.7 Interface with other systems
When it is necessary to interface the EACS with other systems such as intrusion alarm
systems, video surveillance systems, administration systems, intercom, elevator control, etc.
consideration should be given to the following:
a) the type of communication links, the desired availability, reliability and security of
transmitted data associated with those links;
b) the network infrastructure requirements;
c) specific operating commands for example, call for elevator, selection of floor and
destination;
d) reporting commands associated with elevator control.
8 System installation
8.1 General
Prior to commencing work, all relevant safety requirements should be considered.
Electrical installation methods shall comply with current national and site local regulations.
The components of the EACS should be installed in locations that ensure adequate security of
operation and permit easy access for maintenance and service.
All system components should be suitable for the environmental conditions in which they are
to operate.
Care should be taken during the selection of components to ensure all system components
are compatible. Where uncertainty arises the appropriate consultation should take place, e.g.
with the component manufacturer, supplier, a test house or another relevant third party.
The results of the risk assessment shall determine the security grades of the area zones
within the protected area. The access points to those area zones shall be of an equivalent
grade or higher. For each area zone separate access levels may be defined.
With the exception of the user interface, equipment critical to the security integrity of the
access control system shall not be located within an area zone designated as having a lower
security grade than the highest grade of the protected area it is controlling. Refer to Figure 4.

The installer shall make the system owner aware of any specific functionality that shall be
implemented in order to meet the necessary organizational and constructional measures that
are required for the proper operation of the EACS. For example the detection/prevention of
two or more persons attempting simultaneous entry (singularisation) is recommended for the
implementation of anti-tailgating measures.
Consideration should be given to routing cables only within the protected area (see 8.2.2).
8.2 Installation planning
8.2.1 Equipment
The equipment used in installations covered by this standard shall be compliant with the
requirements covered by IEC 60839-11-1 for the applicable security grade and environmental
classification.
The equipment should be installed in accordance with the manufacturer's instructions by
suitably trained personnel. If the installation of a component in accordance with the
manufacturer’s recommendations is not possible advice should be sought from the
manufacturer and this should be recorded in the as-built documentation.
When the EACS is using existing communication (network) infrastructure at the customer site
attention should be paid to ensure there are sufficient capacity, performance and protection
measures in place to allow proper operation of the EACS for the selected security grade.
The housings for components of an EACS shall be provided with the means to prevent
undetected access to internal elements to minimi
