General overview - SmartRelay 3 system

Controller communication with LSM

The controller does not communicate directly with the database. A distinction must be made with communication between the controller and the database:

• Use in the virtual network: The controller is programmed by LSM and also requests information itself from the VN host using the detected ID medium.
• Use without virtual network: The controller does not request information itself on its own. Changes need to be programmed.

Events on the controller such as a pressed button are transmitted to the LSM database via the CommNode.

Controller communication with the components

A user can log onto up to three readers with an ID medium. The reader forwards encrypted information to the controller, which is located within a protected area. The controller evaluates the information:

• Use in the virtual network: The controller verifies the information with the VN host.
• Use without virtual network: The controller draws on information stored locally when it was last programmed.

If the authorisation was checked successfully, the controller can:

• Actuate an internal relay, which can then be used to activate external devices.
• Transmit a recognised identification medium to an external device via the serial interface.
• Switch one or several outputs via an optional SmartOutput module chain.

The controller can also respond to a digital entry and, consequently, a connected button or similar as an alternative to successful identification.
