The Doormate interlock control system allows up to 8 doors to be controlled with a single central unit; several central units can also be networked for larger interconnected interlock systems. Depending on the equipment of the door panels (operating button with integrated multi-colour status display, emergency stop, time display, light button, etc.), as well as the use of presence detectors in the interlocks, practically any functions can be implemented with the help of a simple-to-use configuration interface, from mutual locking to the implementation of room flushing times after leaving an interlock, direction prioritization, central emergency stop acknowledgement and much more. All statuses, such as door contacts, displays, button positions, etc. can be tracked directly in the configuration software in real time during online operation.
