When designing, the multi-passage controller was consciously omitted - its damage would mean the need to turn off several rooms, which is an unacceptable cost for the hotel. Therefore, in this case, one controller is responsible for one door/room, and the entire operating logic is contained in its internal software (so-called firmware). This solution has all the benefits of having an online system, and at the same time provides high security in the event of hardware, network, or management unit failure.
The online mode allows you to keep an eye on the situation at the facility. On one screen we will see the occupancy of rooms, the temperature distribution in the rooms, or the presence of guests in the rooms. In addition, the automatic notification system will send information about the events and alarms without unnecessary delays. Below is one of the examples:
In the event of damage to the communication bus or the central unit, each of the controllers switches to off-line mode, and the occurring events are recorded in the controller's internal memory. In this case, it is not possible to only issue new cards/keys - and those issued earlier still work properly. After the failure is removed, all events are downloaded by the central unit and made available for review.
Built-in and tested over the years hotel software of the room controller ensures very high stability of operation. Developed by practitioners, it just works.
