MC16-BAC is a controller designed to implement building automation functions within the RACS 5 system.

In this controller, the functions of building automation are performed through the so-called automation nodes. The automation node is a logical state in the controller memory which, on the one hand, can be controlled by the user, and on the other hand, can itself control another state of the controller, in particular, the state of another automation node. The state of the automation node can be replicated on the output lines and thus be used to control systems or devices used in the building (roller shutters, lighting, air conditioning, heating, ventilation and others). The state of the automation node can be controlled manually (function key, remote command, logging on the reader, button connected to the input line) or automatically from the level of time schedules.

In the case of using the so-called RACS 5 Integration Server, it is possible to control the automation nodes and read their status from an external application (e.g. BMS system). As in the RACS 5 access controllers, the input and output lines in the MC16-BAC controller are multifunctional and the output lines can be controlled using priorities and modulation. Depending on the version, the controller supports up to 64 automation nodes.

As in other MC16 series controllers, communication with the VISO management application is encrypted and takes place via the LAN / WAN network. The MC16-BAC controller support is available in the free version of the VISO ST management software and is not limited in the number of controllers supported in the system.
