This licence SKU is used for MP2.8 forward. The generic high-level elevator interface (HLI) allows any facility to create a link between their SiPass integrated system and their elevator management system (EMS) for the purpose of controlling access to floors. Once you have configured your system, the HLI allows you to manage which cardholders are provided with access to which floors and the times of the day they are permitted to have this access. To ensure that the HLI is compatible with any commercially available EMS, a generic elevator protocol is available. This protocol provides all the common commands used by elevator management systems to control access. Note: Each site must create its own protocol translator to interface SiPass integrated with their local EMS. To order the SiPass integrated software extensions, you must first complete a software license order form. Please contact your SiPass integrated supplier for further information.
