BS EN 50131-5-3:2017

What is BS EN 50131-5-3 - Interconnections equipment in intrusion systems about? 

BS EN 50131 is a European standard on alarm systems. The main objective of the BS EN 51031 series is to establish operationally efficient security and protection systems that minimize the risk and impact of hazardous events. 

BS EN 50131-5-3 is one of the parts in the multi-series that applies to intrusion alarm equipment using radio frequency (RF) links and is located on protected premises. 

BS EN 50131-5-3 defines the terms used in the field of intrusion alarm equipment using radio frequency links as well as the requirements relevant to the equipment. 

Who is BS EN 50131-5-3 - Interconnections equipment in intrusion systems for? 

BS EN 50131-5-3 on intrusion systems is relevant to: 

• Manufacturers of alarm systems  
• Manufacturers of intrusion alarm equipment 
• Alarm security centres  
• Product designers 
• Local authorities 

Why should you use BS EN 50131-5-3 - Interconnections equipment in intrusion systems? 

An intrusion system is a network security technology originally built for detecting vulnerability exploits against a target application. 

BS EN 50131-5-3 provides best industry requirements for: 

• Immunity to attenuation 
• Immunity to collision- to ensure a high level of confidence in the transmissions of alarm and monitoring messages thus reducing the probability of equipment on the same system causing interference by design and possibly leading to loss or corruption of information 
• Immunity to substitution- to prevent reduction in the security of the system from unintentional messages and component substitution  
• Immunity to interference- to check the ability of the receiving equipment to discriminate between the desired signal and the interfering RF signals 

BS EN 50131-5-3 also provides requirements for RF links monitoring.  

Along with these requirements, the tests necessary to verify these immunities are also covered. 

With standardized terms and definitions, entities dealing with alarm systems and related equipment can avoid misinterpretation and miscommunication. This can be particularly helpful to efficiently carry out risk-mitigating tasks. 

Overall, BS EN 50131-5-3 can be your one-stop guide to ensure radiocommunication of alarm systems use RF are efficient enough to play a positive role in protection against crime.
