Grading | 等级

Alarm systems and products relating to intruder systems are graded depending on the level of security they offer. An intruder alarm is only graded as high as its lowest component which means that if a grade 3 system has one grade 2 device on it, the whole system is downgraded to grade 2.

 

与入侵者系统相关的报警系统和产品根据其提供的安全级别进行分级。 入侵者报警只有最低级别，这意味着如果三级系统上有一个二级设备，则整个系统降级到二级。

 

Grade 3	Grade 2	Grade 2x

 

• Grade 3 - Intruders are expected to be conversant with the alarm system and have a comprehensive range of tools and portable electronic equipment
  
  3级- 入侵者预计熟悉报警系统，并拥有全面的工具和携带式电子设备。
• Grade 2 - Intruders are expected to have a little more knowledge of the alarm system and use a general range of tools and some specialist equipment
  
  2级-入侵者预计会有更多的警报系统知识，并使用一系列的工具和一些专业设备
  
• Grade 2x - This system is the same as a Grade 2 but without any signalling capabilities
  
  2X级- 和2级系统一样，但是不具备发送信号功能。
