What’s in a security system Grade?

TECHNOLOGY

The standard’s requirements for a Grade 4 system are very high, so it’s more uncommon in mass-market systems. Wired security systems will ususally be Grade 3 while wireless ones will be awarded either Grade 1 or Grade 2.

The higher the grade, the more resistant the security system is. Alarm system grading has been in place in the UK for more than 16 years and is an everyday part of alarm system specification and installation today. The two grades which matter in the vast majority of installations are Grade 2 and Grade 3, and it’s worth spending a moment to reconsider how the differences between these grades are defined.

Grade 2 systems are specified for low to medium risk applications, where there is a higher threat than Grade 1 (which is defined as a site where an intrusion being unlikely). In such cases, potential intruders are expected to have some degree of knowledge about how an alarm system and its peripheral devices

When evalutating a security system, its stability and scope will be reflected on the Grade it receives. The Grades range from 1 to 4; with 1 being a basic level – for example, protecting front door access, and generally used for applications with minimal risk and 4 for high risk applications where a super secure system is needed.
