British Standards for Intruder Alarms
When safeguarding your business, intruder alarm systems are your frontline defenders. Adhering to British Standards is essential for ensuring the effectiveness and reliability of these systems. Whether you’re contemplating an upgrade or a new installation, understanding the significance of British Standards for intruder alarms is crucial.
In this blog, we will delve into the role of standards in enhancing intruder alarm security and provide a comprehensive overview of the relevant British standards, including a detailed explanation of the BS EN 50131 regulations, alarm grades for classifying security levels, system design and installation requirements, alarm communication guidelines, and maintenance and monitoring best practices.
The Significance of British Standards for Intruder Alarm Systems
British Standards are more than just guidelines; they represent industry quality, reliability and security benchmarks. They ensure your security system operates at its best, offering your business peace of mind and robust protection.
The standard exists to help insurers, intruder alarm companies, customers, and the police achieve a complete and accurate specification of the supervision required in particular premises. Complying with these standards guarantees a higher level of security and can positively influence your insurance coverage and legal standing in case of an incident; as such, it’s a fundamental standard for I&HAS professionals and is recognised throughout the UK and Europe.
Overview of British Standards for Intruder Alarm Systems
Whilst several standards are relevant to intruder alarm systems, one of the most crucial series is the BS EN 50131.
BS EN 50131 series: European standards for Intruder Alarm Systems
The BS EN 50131 series is a comprehensive set of European standards that covers various aspects of intruder alarm systems. Adopted by the British Standards Institution through their PD6662 scheme, the BSI introduced these European guidelines to boost intruder alarm standards across the UK.
The BS EN 50131 series can be broken down into several key elements;
EN 50131-1: This BS EN 50131 standard element outlines the general requirements for intruder alarm systems. It covers topics like system components, environmental conditions and operational performance.
EN50131- 2-6: Focuses on detectors used in intruder alarm systems. For example, it specifies the requirements for magnetic conditions and operational performance.
EN 50131-3: Details the requirements for control and indicating equipment. It defines features like user interfaces, power supply requirements, and alarm verification procedures.
EN 50131- 4: Covers requirements for warning devices. It provides guidelines for the design and functionality of sirens, bells and other warning devices.
EN 50131-5-3: Specifies the requirements for motion detectors, including passive infrared sensors. It addresses issues like detection patterns, sensitivity, and false alarm immunity.
EN 50131-6: Deals with requirements for hold-up devices. It is relevant for systems that include panic buttons or duress alarms.
These European standards ensure that intruder alarm systems are designed, installed and maintained to meet specific safety and security criteria.
Alarm Grades: Classifying Security Levels According to BS EN 50131
One of the critical aspects of the BS EN 50131 series is the classification of intruder alarms into different security grades. This grade is described in terms of the type of intruder and how much effort they would put into accessing the premises. These grades help define the level of security and reliability a system can provide.
Grade 1: These systems offer essential protection and are suitable for low-security applications, such as residential properties. They typically include minimal intruder detection features. A Grade 1 Intruder Alarm is generally only ideal for residential properties without an insurance requirement for an alarm system.
Grade 2: Designed for moderate security needs, Grade 2 systems are appropriate for most commercial and small business applications and are suitable for properties at a slightly higher risk of theft. In general, these are areas where there may be items of interest to experienced thieves.
Grade 3: Grade 3 Intruder Alarms are recommended for high-risk residential and most commercial properties, including busy retail shops. These systems are intended for high-security environments where a robust response to potential threats is essential. They feature enhanced security measures and tamper resistance.
Grade 4: The highest level of security, Grade 4 systems are suitable for critical infrastructure and high-value assets. These intruder alarms are recommended for highly high-risk residential and higher-risk commercial properties like banks. They provide maximum protection against intrusion and tampering.
Understanding the intruder alarm grade that best fits your business’s security requirements is crucial for adequate protection.
System Design and Installation: Requirements for Intruder Alarm Systems
Effective system design and installation are fundamental to the functionality of your intruder alarm. Compliance with BS EN 50131 standards ensures your alarm system is tailored to your business’s security needs. For instance, standards dictate the need for a thorough risk assessment, helping determine the system’s precise requirements and the optimal placement of sensors.
Alarm Communication: Guidelines for Signalling and Transmission
Communication is a critical aspect of any alarm system. The standards guide how alarms should be signalled and transmitted to relevant authorities or monitoring centres. For example, they specify that signalling devices should connect to an alarm receiving centre (ARC) to ensure prompt and accurate response in case of an intrusion.
Maintenance and Monitoring: Best Practices for Intrusion Alarm Systems
Regular maintenance and monitoring are pivotal to the ongoing effectiveness of your alarm system. Standards define best practices for these activities, including how often inspections occur and what aspects should be assessed during maintenance checks. These practices ensure that your system remains in peak working condition.
Compliance and Certification: Meeting British Standards for Intruder Alarms
Compliance with British Standards is not only a testament to the quality of your security system but is often a requirement for insurance coverage. Many insurers may require your alarm system to meet specific standards to qualify for coverage.
