1   Scope This British Standard gives recommendations for the design, installation, commissioning, maintenance and operation of detection-activated VSS , whether permanent or temporary/portable. It is intended for use by VSS companies , including the installation and maintenance engineers working for the VSS company . This standard applies irrespective of the length of time the VSS are installed and/or whether the equipment can be re-used on another site. This standard provides recommendations for two types of system, Type A and Type A+, which might differ in design based on the results of a threat assessment and risk analysis, which takes into account the threat and consequences of an incident occurring. A Type A system sets the minimum recommendations applicable to all systems within this scope. A Type A+ system design would include all Type A recommendations, with additional security features to detect or prevent the system being compromised.
