Choosing Your Alarm System
Alarm Security Grades
All our alarm systems are designed to meet a security grade in British Standards.
Grades 1-4 describe the level of security that they provide. Your insurance company may specify a particular grade of system to quality your insurance cover, depending on the risk and what you are protecting.
An overview of the security grades detailed in BS EN 50131 – 1 are as follows:
Intruders are expected to have little knowledge of the alarm system and may be restricted to a limited range of easily available tools.
Intruders are expected to have a little more knowledge of the alarm system and use a general range of tools and some specialist equipment.
Intruders are expected to be conversant with the alarm system and have a comprehensive range of tools and portable electronic equipment.
To be used when security takes precedence over all other factors. Intruders are expected to have the resources to plan an intrusion in detail and have a full range of equipment, including the means to substitute vital components in the alarm system.
