LOB 1000/2000 Adel System • Opened using RFID cards, • Battery powered, • For high-occupancy facilities, • Wide range of additional devices. The locks are opened using proximity cards. Access authorization registered on the cards (offline mode) decides whether a door can be opened. When the door is closed, the handle is blocked in the horizontal position, sending out a discrete but clear indication that the door cannot be opened. The internal handle opens the door at all times. The LOB 1000/2000 hotel system also includes items such as a hotel power switch, wall-mounted scanner, elevator controller, encoder, software, PMS interface for external systems and proximity key-cards. All of these accessories are compatible with the LOB 5500 system, which makes the system even more universal.
