What type of intruder alarm grading does my premises require?
If you’re unsure as to the grade of alarm your business requires, the first step is to have a risk assessment carried out on your property. This is another key recommendation within the EN50131 guidelines. It will highlight all risk factors to establish the most suitable grade of system required.
Each and every component within an intruder alarm system is graded. So it’s important to note that the overall grading is equal to the lowest graded component.
For example, if you have a grade 2 certified detection sensor and a grade 3 certified alarm transmission system, then the system as a whole is rated at just grade 2.
