Product Description

CX442 – Access Controller

The CX442 Access Controller is a versatile Access Controller with numerous features to enable a complete access solution. It has the ability to function as a Stand-alone or “on-line” unit. It is designed using the most up-to-date technology in order to meet the requirements of a vast number of access control applications.


  • Personal Access Control.
  • Vehicle Access Control.

Specific Features

  • Able to process 4000 users.
  • Microprocessor based with non-volatile memory and database functions.
  • Configurable relay switching time.
  • Access Tags may be programmed into the unit from either of the two readers (Wiegand or Clock&Data).
  • Users may be voided, validated erased.
  • All critical settings such as programming, voiding and validating functions are protected by an access code.
  • User data may be controlled via a Personal Computer.
  • Transactions may be logged online.
  • 3500 offline transactions.
  • Surge protection on inputs.
  • Heavy duty switching relays.
  • Simple menu navigation via keypad.
  • Visual output via a large 4 digit, seven-segment display, and two LED’s to indicate User status.
  • Alarm input and two Alarm relays.
  • Buzzer output.
  • Two Free-exit inputs.
  • Two “Door-open” inputs/Arming inputs.
  • RS-232 or RS-485 Communications.
  • Real-Time-Clock to record events.
  • Communication with up to 16 Reader Expanders, thus 34 readers.
