Rack lock (bus) DoorLock-RA4 – MANUAL



The DoorLock-RA4 is a wired locking solution for IT racks and distribution cabinets. The DoorLock offers the possibility of two-factor authentication via a touch PIN keypad and an RFID reader. In addition, the position of the lever on the DoorLock is sensed via an integrated magnetic contact.

The DoorLock requires a suitable remote station for operation. This remote station is formed by the network-capable devices AccessManager (SmartRelay) or SmartPDU, which act as both bus gateway and power supply.

For central management, an AccessManager, SiteManager or AlarmManager is required in the MAIN-DEVICE operating mode. Teach-in and configuration are performed entirely via the KentixONE web interface. The maximum cable length between gateway and DoorLock is limited to 100m. Up to 16 DoorLocks can be taught-in to one AccessManager (SmartRelay). With a SmartPDU as gateway, the number is limited to 2 DoorLocks.
