The European standards introduce the concept of grading systems according to the degree of risk of intrusion

Each grade of system has particular requirements for certain components. The equipment and alarm transmission system incorporated in a system must itself be of a suitable grade to satisfy the overall system grade. E.g. if a system is to be designed and installed to be grade 3, and it incorporates PIRs, then each of these PIRs must meet the requirements for grade 3 PIRs. If just one  grade 2 PIR is fitted, the entire system is then a grade 2 system. The grade of system cannot be higher than the lowest grade of components or used within it.  

Assessment relates solely to the grading and the design of the Intruder Alarm System according to DD CLC/TS 50131-7. The grading and design are based on a survey of the premises and information available at the time, including any valuations or other information provided by the customer or the customer’s representative (e.g. the insurer).

The European Standards also define 4 environmental classes of equipment, according to the nature of the situation in which the equipment will be used

The environmental class of components must be appropriate to the environmental conditions at its position of application.
