2 Device description 
 
 
Unless otherwise specified, the descriptions provided in this chapter apply to  
  Compact Reader MIFARE and Compact Reader LEGIC  
 
The Compact Reader either controls and monitors access control at the access points, or records 
coming/leaving bookings as part of time registration.  
Depending on the firmware option, the Compact Reader works as a standalone component or in 
online operation is linked via an RS-485 interface to an access manager or time registration 
terminal.  
The robust reading properties of the integrated antenna permit direct mounting on metal surfaces 
while maintaining almost constant function and convenient user identification. The integrated 
display elements signal both the operating state and access decision visually as well as 
acoustically. 
Thanks to the new quickwire technology, installation is quick and easy. The device is wired to  
the mounting plate plug; the housing with integrated electronics is clicked on with ease and fixed  
in position.  
Not only a frame contact, but also a door opener key or door handle contact can be connected for 
monitoring of the access point. The door opener is activated by the fitted relay. 
If CardLink standalone components are used, the Compact Reader supports validation and 
devalidation functions.
