scope:

NPR-CLC/TS 50131-9 is available for use where alarm verification methods are considered necessary. It provides recommendations for the addition and use of alarm verification technology in Intrusion and Hold-up Alarm Systems (I&HAS) installed to comply with EN 50131-1. These recommendations should be incorporated into the respective standards in the EN 5013x series. This Technical Specification does not detail methods of alarm verification relying solely on Alarm Receiving Centre (ARC) procedures, but does not preclude their use. This Technical Specification describes alarm verification methods that could be applied and details applicable to system and equipment design. The framework limits the range of options in order to provide for local regulations and circumstances, whilst permitting a standardised approach to equipment design. This Technical Specification also provides (in Annex A) recommendations for equipment in order to permit the manufacture of standardised equipment to provide the functionality needed by an I&HAS incorporating alarm verification technology. The associated guidelines for use in ARCs to monitor notification from such I&HAS can be found in EN 50518-3.
