Introduction
This European Standard applies to a security fog system that is part of an Intruder and Hold-up Alarm
System (I&HAS) and is used both as a security deterrent device for building security and as a crime
reduction device for the protection of people.
This European Standard is intended to assist insurers, intruder alarm companies, customers and the
police in understanding the principles and specification of a security fog system.
The purpose of a security fog system is to reduce the visibility in a protected area by the use of a
non-toxic fog in order to form a barrier between the criminal and the criminal’s intended target.
This European Standard is not intended to cover standalone or mobile security fog systems.
This European Standard has been designed to be flexible enough to encourage and encompass
future developments in the field of security fog systems.

1 Scope
This European Standard specifies the requirements for security fog systems as a part of an I&HAS. It
covers application and performance and also gives the necessary tests and trials to ensure efficiency
and reliability of such obscuration devices.
This European Standard also gives guidance on the criteria for design, installation, operation and
maintenance of security fog systems.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this document, the terms and definitions given in EN 50131-1 and the following
apply.
3.1.1
confirmed intrusion
signals or messages emanating from two or more independent intrusion detectors indicating there is a
high probability that a genuine intrusion or genuine attempted intrusion has occurred within a specified
timeframe
3.1.2
obscuration
the reduction in visibility as a result of the activation of a security fog system

– 7 – EN 50131-8:2009
3.1.3
protected area
the designated space the security fog system is designed to restrict the visibility in when operated
3.1.4
security fog system
a device (or a series of separate independent components that make up a device) or system within
tamper resistance housing(s), that, when activated, produces a dense artificial fog, from a
consumable, to reduce visibility in the protected area
3.1.5
verification
the process whereby the security fog system will only operate once the Intruder Alarm System (IAS)
has operated and a detection device in the area of the security fog system has triggered or an Hold-up
Alarm System (HAS) has been operated
3.1.6
wet fog
this may result from incomplete atomisation of the fogging agent causing a direct spray or spatter from
the fog ejection nozzle. This may also result from poor atomisation of the fogging agent causing
individual fog particle size to be too large. Such large particles may fall down and settle on level
surfaces as a greasy residue
3.2 Abbreviations
For the purposes of this document, the abbreviations given in EN 50131-1 and the following apply.
EMC Electromagnetic compatibility
IK Degrees of protection provided by enclosures for electrical equipment against
external mechanical impacts
IP Ingress protection classification
LEA Law Enforcement Authority (Police or governmental body that responds to
activations from security systems)

in accordance with EN 50131-1.
EXAMPLE 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 may be expected to vary between -10 °C and +40 °C with the average relative humidity of
approximately 75 % non-condensing.
4.2 Environmental tests
For all operation the security fog system shall not activate, generate tamper, fault or other signals or
messages when subject to the specific range of environmental and EMC conditions and shall continue
to function normally.
The following Class II level environmental tests from EN 50130-5 shall be applicable when testing the
security fog system:
a) Clause 8: dry heat operational;
b) Clause 10: cold test operational;
c) Clause 14: damp heat, cyclic operational;
d) Clause 17: sulphur dioxide (SO ) (endurance);
e) Clause 20: impact operational;
f) Clause 22: vibration sinusoidal (operational);
g) Clause 23: vibration sinusoidal (endurance);
h) Clause 27: electromagnetic compatibility, immunity (operational).
5 Access levels
The access levels used in this standard shall be as stated in EN 50131-1:2006, 8.3.1, except for
access level 2. Access level 2 “user” shall not be able to access the security fog system.
6 Regulation requirements
6.1 General
The security fog system shall operate to the following minimum relevant European regulations.
6.2 Electrical safety
The electrical (safety) construction of the security fog system shall be to EN 60065.
