What are the intruder alarm system grades?

The key element of the EN50131 standard is the system of grades it outlines. These classify the level of sophistication that is required for the alarm system installed. The higher the risk of crime to your property, the more sophisticated the system you will require and the higher the grade.

There are four intruder alarm grades, which include:

  • Grade 1 – Intruders are unlikely to target the premises.
  • Grade 2 – There’s a higher risk of theft due to valuable property being kept on site.
  • Grade 3 – There is a substantial threat from experienced intruders due to high-value contents.
  • Grade 4 – The property has a very high risk of being targeted by organised criminals.
