LOB 5500 Adel hotel lock (HZ55M-18)

The LOB 5500 lock includes a complete assembly set. It consists of:

  • a LOB 5500 electronic escutcheon,
  • an E mortise lock with monitoring,
  • a half cylinder insert,
  • a striker for E mortise lock,
  • an installation set.

The LOB 5500 lock is designed for installation on doors. The lock compares authorization data stored on the card held near the scanner and, upon confirming their conformity, couples the handle with the spindle of the mortise door lock. When the door is locked, the handle can move freely, but cannot open the door. The lock uses a durable coupling and handle mounting system. It is therefore suitable for installation in doors experiencing high traffic intensity, as well as in EI30 fire doors (optionally). 

The lock stores in its memory any opening attempts and other events. Upon the transfer of this data to the software, a list of events can be created for a specific user card or for a specific door, in order to serve as evidence.

The lock is powered by standard AA batteries. A low battery status is indicated well in advance. If necessary a 9V battery can be connected to contacts situated in the lower section of the housing, alternatively a mechanical key can be used.
