Intercom Control Unit ACO CDNP7ACC ST central unit with heater and LCD, RFID master (MPN 15072)

ACO CDNP7ACC ST central unit with heater and LCD is a control module for door entry and intercom systems. It integrates an LCD display for status and menu navigation, an internal heater to maintain reliable operation in low temperatures, and RFID master functionality to manage proximity credentials. The unit is intended for installation in residential buildings, apartment complexes or small commercial sites where centralised access control and clear local feedback are required.

Advantages

The unit combines display feedback, environmental protection and RFID management in a single compact module. An integrated heater reduces condensation and ensures consistent performance in cold environments, while the LCD provides clear information about system state and configuration. As an RFID master, the unit supports centralised credential enrolment and access logic, simplifying user management and reducing the need for additional hardware.

Suitable for

• Residential apartment entry systems requiring centralised access control
• Small office buildings and commercial premises with RFID user management
• Installations in cold climates where internal heating prevents condensation and freezing
• Systems that need on-site visual status and configuration via an LCD interface

Key specifications

• Function: central intercom/control unit with RFID master capability
• User interface: integrated LCD for status display and menu navigation
• Environmental resilience: built-in heater to maintain operating conditions at low ambient temperatures
• Application: supports management of access rights and system settings for door entry systems
• Compatibility: designed for integration with standard door entry/intercom hardware and RFID credentials

How to use

Mount the ACO CDNP7ACC ST central unit according to the installation manual within the system cabinet or designated enclosure. Connect power, intercom lines, door release circuits and RFID readers as specified by the system wiring diagram. Use the LCD interface to access system menus, configure time and date, enrol RFID credentials and assign access rights. Verify heater operation to ensure the unit maintains appropriate internal temperature in cold installations. After configuration, test entry calls, RFID authentication and door release functions to confirm correct operation.

Usage recommendations

Install the unit in a ventilated enclosure with correct electrical protection and follow local wiring regulations. For reliable RFID enrolment and read range, position readers according to manufacturer guidance and perform post-installation testing in different environmental conditions. Regularly verify firmware and configuration backups and inspect the heater function before the cold season.
