Universal Interconnectivity Interface (UII), The 519 motorized multiple locking system and the 509E motorized lock are devices that have basic electronics. All basic functions required for operation and a Hi-O interface are integrated. If additional functions such as signal contacts, time settings, additional door contacts, etc. are required, the UII 901-IC-4 is used., The lock electronics and the UII 901-IC-4 communicate with each other via the Hi-O bus interface and the UII 901-IC-4 takes over control. If the UII module is used, the control line in the lock can be deactivated and all control and monitoring functions are carried out via the BUS connection. This means that electrical manipulation of the system via the connecting lines is impossible. The following messages and settings are then possible:, Messages via potential-free contacts: Relay status via LED display (to check the lock status. Is an interface to the building management system), alarm, control, revolving door drive, door handle / profile cylinder status, door open / closed, locked, permissible line length max. 20 m lock UII model, Settings: unlocking time 2-28 sec., button function, toggle function, escape route function, access control function, additional inputs: door contact, release, smoke detector, fire alarm system, smoke detector reset
