What is BS EN 50131-8-Security fog devices about?
BS EN 50131-8 is a European Standard on installed alarm systems which is the eighth part of a multi-series that specifies the requirements for security fog devices as part of an intruder and hold-up alarm system (I&HAS). It covers application and performance and also gives the necessary tests and trials to ensure the efficiency and reliability of such obscuration devices.
BS EN 50131-8 also gives the best guidance on the criteria for design, installation, operation, and maintenance of security fog devices.
Who is BS EN 50131-8- Security fog devices for?
BS EN 50131-8 on security fog devices are relevant to:
- Manufacturers of fire detection and fire alarm systems
- Manufacturers of I&HAS
- Alarm receiving centres
- Product designers and engineers
- Installers
- Police
- Insurers
Why should you use BS EN 50131-8- Security fog devices?
Security fog devices are used both as a deterrent device for building security and as a crime reduction device for the protection of people.
BS EN 50131-8 applies to a security fog device that can be connected to an I&HAS. It can assist insurers, intruder alarm companies, customers and the police in understanding the principles and specifications of a security fog device.
Compliance with BS EN 50131-8 can ensure security for devices offer optimum and efficient functionality by reducing the visibility in a protected area with the use of a non-toxic fog, to form a barrier between the criminal and the criminal’s intended target. The protection requirements ensure that the security fog device operates in a way that does not harm persons and other equipment in its vicinity.
If you are a manufacturer, the testing procedures can further help demonstrate reliability and credibility of your products by minimizing risk of overall product failure.
What’s changed since the last update?
BS EN 50131-8:2019 supersedes EN 50131-8:2009, which is withdrawn. The technical changes as compared to the previous version are:
- The standard no longer views a group of parts capable of generating fog as a system and instead considers it to be a device (possibly consisting of separate parts)
- All Security Fog Devices shall meet Environmental Class II
- Requirements for pressure vessels and energy efficiency measures are now included. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights
