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.

All current amendments available at time of purchase are included with the purchase of this document.
