Product Features & Benefits

These controllers are components of an online access control system linked to Norpass3 Access Control Management Software via either TCP/IP or RS485.

The CRC220-4 can be used to control access through up to four doors or barriers with read-in control and free exit, while supporting a wide range of managed access control features and a comprehensive range of interface formats. The enclosure houses 2 two-door interface modules plus an integral power supply unit.


  • Easily managed using simple centralised management of data
  • Choice of mix and match module types enables cost-effective network structure
  • Support for a wide range of card formats and card reader interfaces makes it the ideal choice for enhancing an existing access control system
  • Security levels can be tailored to customer needs using optional security features
  • Improved visitor card management when used with our card capture reader
  • Meets demanding customer requirements through a choice of enclosures with tamper alarms fitted as standard plus features such as fire alarm control input, individual door alarms and configurable inputs and outputs.
