You can request SAM lockchart data individually or as part of a subscription. You will be provided with the lockchart data once if you order individual data. The fixed price for the data requested does not depend on the size or type of system. If you have not taken out a data subscription, you will be billed for each data request. This type of invoicing is more appealing for smaller locking installations with just a few orders per year. If you order a SAM data subscription, there is a fee for each locking installation per year. However, you can request data for that locking installation as often as you like within the subscription period - without charge. A subscription is therefore beneficial for locking installations for which it is likely additional requests or expansions will be made. As there is currently no automatic data provision for subscription customers, please add an additional item to every order or complaint with the article XDA2.
