CDVI CA-A470-A Centaur 2-Door Expansion Module

Increase door coverage and simplify installation with the CDVI CA-A470-A 2-Door Expansion Module—an efficient control panel module designed to extend Centaur access control where you need it. By using Centaur’s E-Bus technology, the CA-A470-A lets you mount reader, keypad, lock and door-contact I/O close to the secured entry while running a single cable back to the CT-V900-A, reducing labor and material costs. The module adds two doors per unit and supports common reader formats like Wiegand and Magnetic Stripe Track II, enabling quick integration with existing security and surveillance hardware. With local lock outputs, four inputs for door contacts/REX, and six reader outputs for LEDs and buzzer feedback, technicians gain on-site control and faster troubleshooting. Rated for auxiliary current of 500mA and powered at 16VAC, the CA-A470-A provides reliable performance for commercial monitoring and access control networks. Ideal for multi-door facilities, branch locations, and retrofit projects—add this CDVI expansion module to streamline deployments and improve system scalability.
